摘要： For use in a perforating gun assembly which incorporates an explosive for detonation of a string of shaped charges, all the explosive materials forming a significant, violent pressure shock wave propagated up a cased well borehole, a pressure actuated switch includes an enlarged piston having a head exposed to the pressure shock wave, a stem connected to said head, bifurcated fingers capturing a resilient material therebetween to permit flexure, a surrounding sleeve which is made of metal and defined in multiple portions, and a plurality of metal contacts contiguous to said stem and adapted to be selectively contacted by said metal sleeve to either make or break on movement of said piston.

摘要： For use with a wire line supported tool adapted to be run in open hole, a wire line connector to be installed between the wire line and at the top of the tool is set forth. The line moving apparatus of this disclosure preferably incorporates concentric telescoping sleeves with guide slots and cooperative protruding lugs. This apparatus attaches to the top end of a tool which is to be held stationary. This enables the supportive wire line to be continuously moved with stroking motion to thereby prevent pressure differential sticking at key seating the mud cake in the open hole.
摘要翻译：为了与适用于开孔的线缆支撑工具一起使用，将安装在线缆和工具顶部之间的线缆连接器。本公开的线移动装置优选地包括具有引导槽和协作突出凸耳的同心伸缩套筒。该装置连接到要保持静止的工具的顶端。这使得支撑线路能够随着行走运动而连续移动，从而防止在打开孔中的键盘上的压块上的压差粘附。
