Remote control and monitoring of engine control system

Abstract

Systems and methods for controlling a drilling rig are disclosed herein. A driller can select between modes: local, human-machine interface (HMI), and automatic. In a local mode a motor operator is instructed to operate a genset for the drilling rig. In a Remote mode the driller can operate the genset directly without the need for a motor operator to start or stop the gensets. In an automatic mode, the genset is controlled according to a well plan including a power consumption schedule.

Description

BACKGROUND

Drilling rigs are typically operated by a driller and a motor operator. The motor operator operates the engines/generator (sometimes referred to as gensets) including starting, idling, and running one or more gensets that provide the power to the drilling rig. A genset is an engine-generator or portable generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an engine-generator set or a gen-set. In many contexts, the engine is taken for granted and the combined unit is simply called a generator. In addition to the engine and generator, engine-generators generally include a fuel supply, a constant engine speed regulator (governor) and a generator voltage regulator, cooling and exhaust systems, and lubrication system. Units larger than about 1 kW rating often have a battery and electric starter motor. Very large units may start with compressed air either to an air driven starter motor or introduced directly to the engine cylinders to initiate engine rotation. Standby power generating units often include an automatic starting system and a transfer switch to disconnect the load from the utility power source when there is a power failure and connect it to the generator. In the oilfield, a driller instructs the motor operator when to start, stop, idle, etc. the various gensets. Much of the success of the drilling operation depends on how these two individuals operate together to operate the drill rig. There are several inefficiencies that arise from this relationship.

SUMMARY

Various features of the present disclosure are described herein. Embodiments of the present disclosure are directed to a system for operating a genset for a drilling rig. The system can include a remote (HMI) component and a genset configured to run to provide power to a drilling rig. The remote component is configured to receive instructions to operate the genset and to deliver the instructions to the genset to operate the genset without the intervention of a motor operator.

In other embodiments the system also includes an idle control component configured to operate the genset in automatic idle mode in which the genset will shut off after a predetermined criteria is met and a constant idle mode in which the genset will continue to idle until instructed to stop and wherein the remote (HMI) component is configured to permit selection between the automatic idle mode and constant idle mode.

Further embodiments of the present disclosure are directed to a method of operating a drilling rig including a genset, including operating a genset to provide power to a drilling operation, and receiving a selection between local mode, remote (HMI) mode, and automatic mode. Local mode requires a motor operator to manually start and stop the genset. Remote mode enables a driller to operate the genset via a HMI without needing a motor operator. In an automatic mode the genset is operated according to predetermined instructions.

Further embodiments of the present disclosure are directed to a system for operating a power system for a drilling operation. The system includes a first terminal at the power system and configured to be operated by a motor operator, and a second terminal at a remote location and configured to be operated by a driller. The system can also include a human-machine-interface (HMI) configured to facilitate communication between the first terminal, the second terminal, and the power system. The HMI permits the motor operator and the driller to communicate about operation of the power system, and permits the driller at the second terminal to operate the power system with requiring action from the motor operator at the first terminal.

In further embodiments the power system is configured to operate in an automatic idle mode in which the power system will shut off under predefined conditions and a constant idle mode in which the power system will continue to idle until instructed to stop from either the first or second terminal. In still further embodiments the second terminal is configured to receive inputs to select between automatic idle mode and constant idle mode.

DETAILED DESCRIPTION

Below is a detailed description according to various embodiments of the present disclosure. FIG. 1 is an illustration of a drilling system 10 in a local configuration including a driller 12, a driller terminal 13, a motor operator 14 (a.k.a. Motor Man), a motor operator terminal 15, and a genset 16. The genset 16 is coupled to a power system 18 and several accessories 20. The power system 18 includes rectifiers, VFD's, drilling motors, tools and a drill bit and components of a drill string coupled to the drill bit that is used to bore a well into the earth. The accessories 20 can be any auxiliary equipment required by the rig, including anything from lights on the rig to electrical systems and HVAC on the rig. The genset 16 can represent one in an array of gensets used by a given rig. Some rigs have multiple gensets, each of which can be operated as shown herein. For purposes of brevity in FIG. 1 a single genset is shown but it is to be appreciated by a person of ordinary skill that the genset 16 can represent multiple gensets, or that individual gensets in an array can individually be controlled and operated according to the systems and methods of the present disclosure.

To operate the genset 16, the driller 12 issues instructions to the motor operator 14 who then executes the instructions. For example, if the driller 12 instructs the motor operator 14 to start the genset 16, the motor operator 14 starts the genset 16 using a key or a button or whatever starting mechanism there is for the genset 16. The driller's instructions are based on the judgement of the driller and depend on the skill and information available to the driller to operate the rig to perform the necessary operations of the rig. This configuration is referred to herein as the “local” configuration.

FIG. 2 is an illustration of a drilling system 30 in a Remote (Human-Machine Interface “HMI”) configuration including a driller 12, a motor operator 14 and a genset 16 according to embodiments of the present disclosure. In the Remote configuration, the driller 12, motor operator 14, genset 16, the power system 18, and accessories 20 can operate the same way they do in a local configuration if the driller so desires. The Remote configuration, however, further includes an HMI 32 that can comprise a monitor and I/O capabilities such as a keyboard and mouse or touch screen or any equivalent I/O methods. The HMI 32 can also include a computer or other equivalent computational equipment. The HMI 32 can interface with the motor operator 14 and with the genset 16 directly, under the direction of the driller 12. For example, if the driller wants to start the genset 16, he can select via the HMI 32 a command to be issued to the genset 16 which can then execute the command to start. The motor man 14 can confirm back to the driller 12 that all is ready to proceed. With this confirmation and using the HMI 32, the driller 12 therefore can bypass the Motor Man 14 and directly control the genset 16. The driller 12 also has the option of communicating with the Motor Man 14 directly if the need should arise. The confirmation from the Motor Man 14 can be required, encouraged, or suggested. In some embodiments the driller can proceed without the confirmation from the Motor Man 14.

The HMI 32 also directs communication from the genset 16 back to the driller 12. From time to time there are issues that arise in the genset 16 or perhaps simply readings of interest. The genset 16 is configured to report these readings back to the driller 12 through the HMI 32. The driller 12 is therefore better informed of the status of the genset 16 without relying solely on the alertness or capabilities of the Motor Man 14.

In further embodiments of the present disclosure the genset 16 can include an idle control component 34 that can include two or more idling settings. An auto idling setting allows the genset to turn on and to idle in preparation for use by the power system 18 or accessories 20. If the need for the genset 16 is not realized within a given predefined time period, the genset 16 will turn off. The time period for shut off can be controlled via the HMI 32. Idling the genset 16 before use will allow the genset 16 to warm up to achieve greater efficiency during use.

In a constant idle mode, the genset 16 is instructed to idle indefinitely with no timer for shut down. The idle control component 34 can be configured to start or stop the genset 16 in response to any criteria given to it by the driller 12 through the HMI 32. For example, on a hot day the genset 16 will need less time (perhaps zero time) to warm up in which case the idle control component 34 will not instruct the genset 16 to idle; rather, the genset 16 will turn on when the power is required. In another example, in a cold environment there may be a need to maintain the genset 16 above a given temperature which may require idling even without an instruction from the driller 12 and without an imminent need for power.

FIG. 3 is an illustration of a drilling system 40 in an automatic configuration according to embodiments of the present disclosure. The system 40 includes a well plan 36 which can be stored on a database or another suitable computer-readable memory component. The well plan 36 can also be referred to as a Rig State or Predictive Control module and it includes information detailing how and when to operate the genset 16. The well plan 36 can be compiled in advance of the drilling operation and can include data regarding the formation in which the drilling is to be carried out and other characteristics of the drilling operation. For example, the well plan 36 can have a schedule of power needs and can instruct the genset 16 to start, idle, stop, etc. according to the schedule. The instructions of the well plan 36 can be communicated to the genset 16 through the HMI 32. The driller 12 also has control over the system and if necessary can alter or stop procedures called for by the well plan 36. The operator 14 can also intervene if he observes a problem or a situation in need of attention.

The HMI 32 can also receive instructions from controller algorithms 33 that can come from operations taking place in a controller at the local machine or at any other related point in the operation. In some embodiments there is no well plan data that drives the need for the genset 16 to be active, but with access to the controller in the form of controller algorithms 33, the genset 16 can be turned on or off as needed. The driller 12 can be given the option to ovverride these inputs through the use of the HMI 32.

FIG. 4 is a schematic graphic user interface (GUI) 42 for the HMI 32 according to embodiments of the present disclosure. The GUI 42 can present a selection to the driller 12 between local, remote, and automatic configurations. In FIG. 4, the driller has selected “local” and the GUI 42 represents this choice in a first window 44. The first window 44 can say “remote” or “auto” if the user makes the selection. The selected choice (local/remote/auto) will be active at any given time. The GUI 42 can include selectable buttons 46, 48, and 50 for local, remote and automatic modes, respectively. The GUI 42 can be a controlled via a touch screen, keyboard and mouse, or any other suitable I/O mechanism. A communication link is established between the genset and the engine controller to gather all the information that is required for the algorithms to make the decisions in the Remote and Auto configurations.

The foregoing disclosure hereby enables a person of ordinary skill in the art to make and use the disclosed systems without undue experimentation. Certain examples are given to for purposes of explanation and are not given in a limiting manner.
