摘要： There is provided a wellhead component (50, 60) installing above a casing hanger on a wellhead (10), the wellhead component (50, 60) having a first bore (52, 62) and having at least one lock screw (55, 65) disposing in a side of the first bore (52, 62). The wellhead component (50, 60) has a first port (56, 66) communicating from the first bore (52, 62) to outside the component (50, 60). A control line hanger (100) installs at least partially in the first bore (52, 62) of the wellhead component (50, 60). At least one lock screw (55, 65) engages the control line hanger (100) when installed therein. The control line hanger (100) has a tubular body (101) defining a second bore (102) from a first end to a second end, the tubular body (101) having a second port (106) with an inlet and an outlet, the inlet communicating with the first port (56, 66) on the component (50, 60). The control line hanger also has a connector (110) supported on the second end of the tubular body (101) and coupled to a control line (120), the connector having one or more flutes communicating with the second bore, the connector having a conduit connecting the outlet of the second port with the control line (120) coupled to the connector.

摘要： Wellhead control line deployment involves replacing the seat/retainer plate of a master valve of the wellhead with a modified retainer plate. The retainer plate defines a first port communicating from a central opening of the plate to outside the plate. A modified bonnet installs on the master valve, and the bonnet has two ports, one communicating with the first port in the retainer plate and the second communicating with a needle valve port. The communication ports are linked by a tube with outside diameter seals that inserts between the retainer plate and the bonnet. A control line hanger can be retained by locking into an adapter sleeve or directly in the back-pressure valve threads of a tubing hanger. The adapter sleeve can be attached to the retainer plate or have a collet to snap into the back-pressure valve threads of the tubing hanger.
摘要翻译：井口控制线部署涉及用改进的固定板更换井口主阀的阀座/固定板。保持板限定从板的中央开口连通到板外侧的第一端口。在主阀上安装一个改进的阀帽，阀帽有两个端口，一个与固定板上的第一个端口连通，另一个与针阀口连通。通信端口通过一根管子连接，外径密封件插入保持板和阀盖之间。控制管线悬挂器可以通过锁定在适配器套管中或直接锁定在油管悬挂器的背压阀螺纹中来保持。适配器套管可以连接到固定板上或者有一个夹头卡入油管悬挂器的背压阀螺纹中。

摘要： A lubricator (10) includes a tubular body (12) through which passes a support member such as coil tubing or wireline, and an elongate slot (18) for inspection of or access to the support. A sleeve (20) mounted on the body (12) is movable between first and second positions to close or open the slot (18). The sleeve (20) is movable by means of a pair of pistons and cylinders (22, 23, 24, 25). O-ring seals (28, 29) are provided on the body (12) above and below the slot (18).

摘要： Subsea lubricator device, comprising a blowout preventer assembly, a tool housing assembly and a stuffing box, intended to be located at a subsea Christmas tree, and methods of circulating fluids in a subsea lubricator. The device comprises a blowout preventer (40) and a lubricator (60). Along the entire length of the device a bypass (46, 66) is located. The bypass communicates fluid with the device via a fluid connection (72) at the upper end of the tool housing and via a valve assembly (51) at the bottom of the blowout preventer. This permits removal of gas or oil being present in the device by circulating the hydrocarbons in the well.
