摘要： A multifunctional rotating control device (RCD) includes an RCD assembly, a multi-way cross, and choke control modules. The RCD assembly includes a body and a rotating sealing assembly, where a bore through hole, two side outlets, and a straight-through outlet are formed in the body. The rotating sealing assembly is provided in the bore through hole, a straight-through cut-off valve is provided at the straight-through outlet, and there are two choke control modules. The two choke control modules are respectively connected to the two side outlets and the multi-way cross, and a side choke extends upward in a direction of the bore through hole. The two choke control modules are integrated onto the RCD assembly, and extend upward in the direction of the bore through hole.

摘要： An actuatable sealing mechanism for sealing a fluid channel provided between two co-axially arranged tubular members having a central longitudinal axis. The actuatable sealing mechanism comprises an elastomeric seal, an axially moveable actuating sleeve member (1400; 2400; 3020) and a radially moveable activating member. The activating member is configured to be moveable in a radial direction in use to translate the actuatable sealing mechanism between an unsealed state and a sealed state. When it is in the sealed state, the activating member axially compresses the elastomeric seal sufficiently to expand the elastomeric seal in the said radial direction to seal the fluid channel.

摘要： A technique facilitates deployment and use of a seal rotating system without retrieving the running tool prior to a drilling operation. The running tool remains with the drill string after deployment of the seal rotating system which saves substantial time by avoiding retrieval of the running tool prior to conducting the drilling operation. According to an embodiment, a seal rotating system is mounted to the running tool and the running tool is connected into a drill string. The running tool is used to position the seal rotating system in a rotating control device housing which may be positioned along, for example, a riser. The running tool is then released from the seal rotating system and is moved downhole as part of the drill string to enable performance of a borehole drilling operation without removing the running tool.

摘要： Dissolvable pump down devices, dissolvable pump down assemblies, and methods to propel a bottomhole assembly through a lateral section are presented. A dissolvable pump down device includes an engageable portion, and one or more expandable pieces that are initially in a first position before the dissolvable pump down device is deployed in a wellbore, and configured to expand from the first position to a second position in response to a force generated by fluid flow of fluid through the wellbore. A diameter of the expandable pieces while the expandable pieces are in the first position is less than the diameter of the one or more expandable pieces while the one or more expandable pieces are in the second position. The engageable portion and the one or more expandable pieces are configured to dissolve after the dissolvable pump down device is positioned at the desired wellbore location.

摘要： What is provided is a method and apparatus wherein a rotating and reciprocating swivel of adjustable stroke length and shearable by ram blow out preventers can be detachably connected to an annular blowout preventer thereby separating the lower wellbore from the riser. In one embodiment the mandrel of the swivel extends through a sleeve/housing. The sleeve/housing has a wiping arrangement of improved configuration that wipes debris from the mandrel, preventing entry of the debris into the sleeve/housing. Ports enable discharge of the removed debris from the area of the sleeve/housing.

摘要： A pressure control device can include an outer housing, a bearing assembly with bearings to rotatably support an inner barrel in the outer housing, a heat exchanger, and fluid passages that communicate between the bearings and the heat exchanger, and a latch assembly configured to releasably secure the bearing assembly in the outer housing. The latch assembly can include a heat exchanger configured to exchange heat with the bearing assembly heat exchanger. Another pressure control device can include a bearing assembly with bearings to rotatably support an inner barrel in the outer housing, fluid passages that communicate with space adjacent the bearings, a pump in communication with the fluid passages, and a gear train connected between the pump and a ring gear secured to the inner barrel.
