The present technology pertains to a measurement device operable to track fluid flow parameters. In particular, the present disclosure relates to a system and method for monitoring various parameters of a dynamic fluid flow using a measurement device having a plurality of sensors disposed on one or more moveable arms.
Current devices used for monitoring fluid flow parameters within a fluidic channel typically include one of a single line of sensors spaced along the diameter of the channel or a plurality of sensors embedded in the side of the fluidic channel Sensor arrangements, such as those dispersed along the diameter of the fluidic channel, are not hydrodynamic and can disrupt the fluid flow throughout the area to be measured, which can result in erroneous readings and inaccurate information. Additionally, in systems where sensors are embedded within the walls of the fluidic channel, the sensors are spread out over a wide area, which can be insufficient to obtain a full understanding of the fluid flow properties throughout the fluidic channel. Collection of limited data as described can lead to inefficient and inaccurate measurements of the dynamic flow.
In order to describe the manner in which the above-recited, and additional, advantages and features of the disclosure can be obtained, a more particular description of the principles briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Understanding that these drawings depict only exemplary embodiments of the disclosure and are not therefore to be considered to be limiting of its scope, the principles herein are described and explained with additional specificity and detail through the use of the accompanying drawings in which:
Various embodiments of the disclosure are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustrative purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without departing from the spirit and scope of the disclosure. Additional features and advantages of the disclosure will be set forth in the description which follows, and in part will be obvious from the description, or can be learned by practice of the herein disclosed principles. The features and advantages of the disclosure can be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features of the disclosure will become more fully apparent from the following description and appended claims, or can be learned by the practice of the principles set forth herein.
Commonly used downhole fluid flow sensors are disposed in a one-dimensional manner within a fluid channel. For example, sensors are disposed in a single line, across the diameter of the channel, or disposed around or embedded in the side of the fluidic channel Additionally, sensors can be spread out over large distances resulting in non-concurrent measurements of the flow within the fluidic channel Such methods provide only a small amount of information regarding the fluid parameters. Failure to obtain information at all points throughout the wellbore can cause errors in calculations relating to flowrate, phase yield, and various other measurements relating to fluid flow which are critical to the stability of the fluidic channel.
Disclosed herein is a sensor arrangement for providing measurements relating to a multi-dimensional area. The multi-dimensional measurement system can provide data for all points throughout a cross-sectional area of the fluidic channel. As such, the measurement device described herein provides a sensor arrangement which allows for a significantly larger amount of data to be obtained.
Specifically, the present disclosure is drawn to a system, method, and apparatus for measuring fluid flow parameters within a fluidic channel. The system and method can use an apparatus such as a hydrodynamic measurement device comprising a plurality of sensors operable to provide flow parameter data throughout the cross-sectional area of the fluidic channel Measurement devices as described herein can be disposed within any fluidic channel including, but not limited to, a pipe, a conduit, a wellbore, and the like. The measurement device described herein can include at least a central body, one or more movable arms, and a plurality of sensors disposed throughout the central body and along the length of the one or more movable arms. The movable arms can be controlled via an actuator to expand out from, and contract towards, the central body of the device. Additionally, the measurement device disclosed herein can be hydro-dynamically designed in order to reduce disturbances within the fluid flow both in the fluidic channel and around the measurement device. In at least one example, the plurality of sensors disposed throughout the measurement device can be arranged such that the sensors are parallel to the flow of the fluidic channel.
The term “sensor” as used herein refers to any device operable to measure and transmit information regarding the immediate surroundings. For example, sensors used in accordance with this disclosure can be operable to detect one or more parameters of a fluid flow including, but not limited to, a fluid flow rate, fluid velocity, fluid level, fluid phase or ID (oil/water/gas), fluid density, pressure within the fluidic channel, and the like.
The term “actuator” as used herein refers to any device configured to modify the behavior of the device, or the behavior of other devices, in response to receiving a command signal.

The logging tools 134 may also include one or more computing devices 136 communicatively coupled with one or more of the plurality of tool components. The computing device 136 may be configured to control or monitor the performance of the tools 134, process logging data, and/or carry out the methods of the present disclosure. In at least one example, the computing device 136 can be operable to receive a signal to control one or more of the plurality of tool components.
In some examples, one or more of the logging tools 134 may communicate with a surface receiver 128, such as a wired drill pipe. In other cases, the one or more of the logging tools 134 may communicate with a surface receiver 128 by wireless signal transmission including, but not limited to, pressure wave transmission (such as mud pulse and continuous wave telemetry), acoustic energy transmission, and electromagnetic wave transmission. In at least some cases, one or more of the logging tools 134 may receive electrical power from a wire that extends to the surface, including wires extending through a wired drill pipe. In at least some instances the methods and techniques of the present disclosure may be performed by a computing device (not shown) on the surface. In some examples, the computing device may be included in surface receiver 128. For example, surface receiver 128 of wellbore operating environment 100 may include one or more of wireless telemetry, processor circuitry, or memory facilities, such as to support substantially real-time processing of data received from one or more of the logging tools 134. In some examples, data is processed at some time subsequent to its collection, wherein the data may be stored on the surface at surface receiver 128, stored downhole in telemetry sub 132, or both, until it is retrieved for processing. In an alternative example, the telemetry sub 132 can include a computing device operable to perform preprocessing of the data downhole. In yet another embodiment, the telemetry sub 132 can include a computing device downhole operable to perform preprocessing of the data, which can then be further processed at the surface.

For example,
The logging facility 168 may include a computing device 166 capable of carrying out the methods and techniques of the present disclosure, including collecting and analyzing data gathered from the measurement device. In this manner, information regarding the fluid flow parameters may be obtained by the measurement device (logging tool 158) and processed by a computing device, such as computing device 166.

As stated above, the logging tools 134,158 described in
As described above, each of the plurality of movable arms 220 can include a plurality of sensors 230 spaced along the length of the arm. In at least one example the sensors are symmetrically located on each side of the measurement device.
The movable arms 220 described herein can provide for strategic placement of the sensors throughout the fluidic channel. For example,
As described above, the one or more movable arms can move independently from one another. Additionally, each of the moveable arms can be configured to collect different, specific fluid parameter measurements at each sensor. For example, the sensors in the measurement device can be operable to detect one or more of fluid velocity, fluid density, fluid temperature, optical ID, and spinner. Furthermore, when the movable arms are expanded outward from the central body of the measurement device, the plurality sensors are distributed at various points throughout the cross-sectional area of the fluidic channel. For example, the plurality of sensors can be located at various distances from the center of the fluidic channel, on the central body of the measurement device, and abutting the sidewall of the fluidic channel Such sensor arrangement can provide a thorough, multi-dimensional evaluation 260 of the fluid parameters at all points throughout the fluid channel, as shown in
Specifically, the design of the measurement device 200 allowing for the flexible placement of sensors described herein can offer several different methods to analyze collected data. In a method where a full analysis is not necessary only a portion of the plurality of sensors 230 can be used to gather information. For example, the outside sensors, such as those near the side of the fluidic channel 205, can be used. In such a partial analysis, the data gathered would allow for a fluid flow analysis to be performed based on circumferential outer sensors and one inner sensor, similar to the processes used currently. In an alternative example, data can be obtained using only sensors placed such that the data points are in a single line across the diameter of the fluidic channel 205. Such arrangement can be made vertically or in a horizontal plane. In an alternative method, data obtained from all sensors within the measurement device can be used to gather information. Such method can allow for the collection of improved logging data and fluid measurement accuracy.
For example, horizontal wellbores can require that the measurement device 200 be able to curve around or have influences from incoming fluids from the reservoir. Such changes in orientation and shape can prevent traditional measurement devices from reaching certain portions of the wellbore. The presently described measurement device 200 is operable to evaluate sections of the channel where useful data may be obtained. For example,
The measurement device 200 described herein can be used to collect data throughout various points within a wellbore. For example, the measurement device 200 can be deployed downhole in the retracted configuration. When the measurement device 200 reaches a desired measurement location a signal can be sent from a computing device 136,166 to the measurement device 200 to actuate the one or more movable arms 220. Once the one or more movable arms 220 are expanded from the central body 210 of the measurement device 200, the device can begin recording fluid flow data. As described above, the measurement device 200 can include contacts that allow for reduced disturbances as the measurement device 200 moves throughout the fluidic channel 205; as such the measurement device 200 can be used to take measurements throughout several points within the fluidic channel 205. The one or more movable arms 220 of the measurement device 200 allow the device to move through deviated and horizontal wellbores which are curved at one or more points within the fluidic channel 205. Once the desired data collection is complete, a signal can be sent from a computing device 136,166 to retract the one or more movable arms 220 back into the central body 210 of the measurement device 200 and the measurement device 200 can be retracted.
As fluid moves through a fluidic channel, materials and sediments within the fluid can cause buildup along the sides of the channel as well as around items disposed therein, including a measurement device. The buildup can include, for example, an increase of paraffin, mudcake, particulate, sludge, or other debris. In at least one example, devices, sensors, and other downhole components can get debris or sludge built up around the devices, causing inaccuracies in the collected measurements. Unless the devices are cleaned, the measurements obtained via the sensors will not provide the accurate information. Typically, traditional measurement devices are required to be removed from the wellbore once the device or sensors have gathered too much buildup to provide useful data, which can result in delays and significant costs.
In at least one embodiment, the measurement device 200 disclosed herein can be configured to be self-cleaning. For example, the measurement device 200 can be operable to remove buildup from the measurement device 200 while disposed downhole. Specifically, as shown in
Both the one or more movable arms 220 and the plurality of sensors 230 can be coupled with a computing device 136,166 operable to measure various fluid parameters. As described above, in at least one embodiment, the plurality of sensors 230 can be coupled with a computing device 136,166 to store the data obtained downhole for later review. In the alternative, the plurality of sensors 230 can be coupled with a computing device 136,166 via wired or wireless communication such that the data can be instantly and continuously reviewed. The computing device 136,166 may include any suitable computer, controller, or data processing apparatus capable of being programmed to carry out the method, system, and apparatus as further described herein.
