摘要
石油井下仪器的推靠器工作时紧贴井壁,在遇紧急情况时需要具有自动收回功能,蓄能器的合理选择和在小直径仪器上的结构设计,表明并联液压碟型弹簧蓄能器是一种较好的选择。
Downhole instrument is close to the borehole wall while setting,it need to have automatic recovery function in case of an emergency,what the reasonable choice on accumulator and the small diameter of the structural design of the instrument indicate that the parallel hydraulic accumulator spring dish is a better choice.
