摘要： A new wellhead housing structure which utilizes identical units of a unique wellhead housing of selected internal diameter and pressure rating. Each wellhead housing utilizes a new flexible bowl ("flexbowl") hanger support ring which may be installed and removed as desired during assembly of the wellhead structure during completion of the well. Each wellhead housing forms an internal circumferential groove to receive the flexible bowl hanger support ring in position to receive and support different kinds and sizes of hangers for casing, protective sleeves, and the like. The flexible bowl support ring is drawn into a contracted position. The contracted support ring will pass through the wellhead housing and is seated by a setting tool. Subsequently, a tubing or casing hanger may be landed upon the support ring and supported by the support ring which serves the same functions as the bowl seat in a conventional wellhead housing. The support ring may be removed by a removal tool.
摘要翻译：一种新的井口外壳结构，其采用相同的单元，其具有选定的内径和压力等级的独特的井口壳体。每个井口壳体都使用一个新的柔性碗（“弯头”）衣架支撑环，可在井的完井期间组装井口结构期间根据需要安装和拆卸。每个井口壳体形成内部周向凹槽，以将柔性碗挂架支撑环接纳在适当位置，以容纳和支撑用于套管，保护套等的不同种类和尺寸的衣架。柔性碗支撑环被拉入收缩位置。承包的支撑环将穿过井口外壳，并由安装工具安置。随后，管道或套管悬挂器可以落在支撑环上并由支撑环支撑，支撑环在常规的井口壳体中起到与碗座相同的作用。支撑环可以通过去除工具去除。

摘要： A fluid resistant electrical connector for a multiconductor electrical cable. The connector comprises a cylindrical shell assembly 20 with a cylindrical insert 34 therein. The cylindrical insert has a plurality of passageways 44 therethrough for receiving a contact receptacle 48 in each respective passageway. A boot seal 100 engages each conductor leading to a respective contact receptacle. Each boot seal has a first portion 102 and a second portion 104 with a coaxial bore therethrough. The coaxial bore has a plurality of internal circumferential ribs 108 therein. The first portion of the boot seal has a plurality of external circumferential ribs 114. A compression plate 122 has a plurality of bores 124 therethrough for receiving and engaging the boot seals. A compression gland 130, engagable with the rear portion of the shell assembly, is adapted to apply axial force to the compression plate which compresses the boot seals. A collet 138 engages the cable 74 and has an outer tapered portion 142 adapted to cooperatively engage a tapered end portion 136 of the compression gland 130. A collet retainer 144 threadably engages the rear portion of the shell assembly and engages the collet 138. The collet is compressed against the cable as the collet retainer is threadably tightened to the shell assembly.
摘要翻译：一种用于多导体电缆的防流体电连接器。连接器包括其中具有圆柱形插入件34的圆柱形壳体组件20。圆柱形插入件具有穿过其中的多个通道44，用于在每个相应的通道中容纳接触容座48。靴形密封件100接合通向相应的接触容座的每个导体。每个靴形密封件具有第一部分102和具有穿过其中的同轴孔的第二部分104。同轴孔在其中具有多个内周肋108。靴形密封件的第一部分具有多个外圆周肋114.压缩板122具有穿过其中的多个孔124用于接收和接合靴形密封件。可与壳体组件的后部接合的压缩压盖130适于向压缩板施加轴向力，该压缩板压缩靴形密封件。夹头138接合电缆74，并且具有外锥形部分142，该外锥形部分142适于与压缩压盖130的锥形端部136配合地接合。夹头保持器144螺纹地接合壳组件的后部并与夹头138接合。夹头当夹头保持器螺纹拧紧到壳体组件时，被压靠在电缆上。
