    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 method of deploying a downhole tool into a wellbore includes: lowering a cable into the wellbore; after lowering the cable, engaging a mold with an outer surface of the cable; injecting sealant into the mold and into armor of the cable, thereby sealing a portion of the cable; lowering the downhole tool to a deployment depth using the cable; engaging a seal with the sealed portion of the cable; and operating the downhole tool using the cable.
