用途目前,大斜度井愈来愈多,大斜度井测井是靠钻杆先将下井仪器推送至井内欲测深度,然后将测井电缆从钻杆内下至下井仪器顶部使它们对接起来即可测井。其中一个关键的技术问题,就是解决测井电缆在井下高温、高压和泥浆包围的情况下,如何与井下仪器可靠地对接起来连成通路并与泥浆绝缘。文中介绍井下湿式电缆联接器就是为上述目的而专门研制的。由于配有井下导向槽,因此,可以与七芯电缆配用测井。
Uses At present, more and more high-deviated wells are well-delineated. Well logging is driven by the drill pipe to push the downhole instrument to the depth of the well to be measured. Then, the logging cable is connected from the inside of the drill pipe down to the top of the downhole instrument Get up to logging. One of the key technical issues is to solve the problem of how well a logging cable can be reliably docked with a downhole tool to become a pathway and be insulated from the mud under the conditions of high temperature, pressure and mud in the well. Described in the article underground wet cable connector is specially developed for the above purposes. Due to the downhole guide groove, it can be used with seven core cable logging.
