Description

BACKGROUND

The hydrocarbon industries, during drilling, completion, and production operations, use various types of equipment that include, for example, wellheads and blowout preventers. More specifically, wellheads and blowout preventers are typically used in conjunction with the drilling rig in cementing operations during completion phases of well construction. Prior to production of a well, the well may be cemented to seal the annulus between a casing and the walls of a wellbore after a casing string has been run down hole. The cementing may, for example, seal a lost circulation zone. Cement may also be used to set a plug in an existing well or to plug a well so that it may be abandoned. Cementing operations may be used to seal intermediate casing strings and various types of production strings.

In order to pump cement into a well, the casing or landing joints with special end adapters are run through the blowout preventer to fluidly connect the cementing equipment on the rig floor to the casing string inside the wellhead. The blowout preventer may be a part of a blowout preventer stack including other pieces of equipment. Conventionally, a blowout preventer is fluidly connected to the wellhead by means of a flange on the casing head or casing spool which is secured using threaded studs and nuts. These flanged connections are time consuming to install and slow the transition of a blowout preventer between various wells. Special adapters are commonly utilized to reduce the connection time by utilizing various clamps, bolts, or threaded mechanisms to secure the blowout preventor to the wellhead.

DETAILED DESCRIPTION

Illustrative examples of the subject matter claimed below will now be disclosed. In the interest of clarity, not all features of an actual implementation are described for every example in this specification. It will be appreciated that in the development of any such actual implementation, numerous implementation-specific decisions may be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort, even if complex and time-consuming, would be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

Further, as used herein, the article “a” is intended to have its ordinary meaning in the patent arts, namely “one or more.” Herein, the term “about” when applied to a value generally means within the tolerance range of the equipment used to produce the value, or in some examples, means plus or minus 10%, or plus or minus 5%, or plus or minus 1° A, unless otherwise expressly specified. Further, the term “substantially” as used herein means a majority, or almost all, or all, or an amount with a range of about 51° A to about 100%, for example. Moreover, examples herein are intended to be illustrative only and are presented for discussion purposes and not by way of limitation.

Embodiments of the present disclosure may provide systems and methods for quickly adapting a wellhead for offline cementing jobs where a rig and blowout preventer may be moved between multiple wells. Additionally, the systems and methods may include slidably engaging cement adapters, that allow cementing connections to more quickly be attached to wellheads than conventional bolt on and threadable connections.

Additionally, systems and methods disclosed herein may use connector clamps that are disposed around the quick connection modules that allow an operator to secure the quick connection modules in a relatively fast and safe manner. The use of such connector clamps facilitates a faster transition between components of a wellhead stack. By facilitating a faster transition between wellhead components through the use of quick connection modules, offline cementing jobs may transition between various wells more efficiently. Various types of quick connection modules will be discussed in detail below.

Turning to FIG. 1, a side cross-sectional view of a wellhead according to embodiments of the present disclosure is shown. In this embodiment, a wellhead 100 is illustrated. The wellhead 100 may be used in offline cementing operations for an intermediate string. Offline cementing operations provide the ability to cement casing off of a rig, thereby allowing the rig to move to other wells to provide other operations, such as drilling or other cementing operations.

Casing head 104 is fluidly connected to a casing spool 105. Casing spool 105 may be used to control wellhead pressure and provide a connection point for an upper end of a casing string 110. Casing spool 105 may be bolted to casing head 110 using a plurality of bolts or may otherwise be mechanically attached to casing head 110.

A proximate, upper end 106 of casing spool 105 may be connected to a lower quick connector 115. Casing spool 105 and lower quick connector 115 may be connected through various mechanical attachments, such as a plurality of bolts. Lower quick connector 115 may have a lower body 120 that includes an inner surface 125 and an outer edge 130. One or more sealing elements 135 may be disposed on the inner surface 125. Sealing elements 135 may be formed from, for example, an elastomeric material, such as rubber, plastics, composites, and the like. In some embodiments, the sealing elements 135 may be elastomeric O-rings, although other types of sealing elements may be used in other embodiments.

Lower quick connector 115 may further be connected to a cement adapter 140. Cement adapter 140 may be removably inserted into lower quick connector 115 without requiring mechanical attachment mechanisms, such as threads, bolts, or the like. Cement adapter 140 includes a cement adapter body 145 that has an outer edge 150 that may engage sealing elements 135. Cement adapter 140 may also include a radial protrusion 155 that extends outwardly from cement adapter body 145.

Turning to FIG. 14, a flowchart of a method for adapting blowout preventers for cementing jobs according to embodiments of the present disclosure is shown. Such methods 800 may include removing (block 805) a connector clamp from an upper quick connector that is attached to a blowout preventer and a lower quick connector that is attached to a wellhead. Removing the connector clamp may include removing one or more bolts, or other mechanical attachments, which are inserted through eye holes in connection portions that are disposed around the quick connectors. By removing the mechanical attachments, the connector portions may separate from the quick connectors, thereby providing access to such components.

Method 800 may also include removing (block 810) the upper quick connector from the lower quick connector.
