摘要
TCP射孔（油管传输射孔）技术是1990年引进的，在现场实际应用中，存在射孔装置配件不配套的实际问题，为此，研制开发了一系列射孔工艺中的配套装置，进行了有关引爆系统及配套装置主要部件的改进。本文介绍的改进装置包括：引爆装置部分的开窗式防砂撞击点火头、压力式点火头下接头、新型环压式点火装置；辅助装置部分有防松双锁定式传爆接头、特殊井作业专用投棒系列（滚轮式投棒、万向滚轮多节投棒、铜质投棒）、减震器（33／4″普通型、5″全通型）、封隔器滑动开孔装置、投棒投捞器等，经现场多个探区及油田作业应用，取得了显著的经济效益和社会效益。
The TCP(Tubing Conveyed Perforation)technology is imported in 1990. The actual problems are existing in the field applications of this system. For this reason,the main components of ignition system and the devices assorted with the perforation gun are improved. These components include the open-window sand prevention impact igniter,the lower connection of pressure-type igniter,and new-type annular pressure igniter in ignition system; the jamming double-locking transmission explcoive connection,a series of special bars used for the operation of exceptional wells such as the roller-type bar,the multiple direction roller multisection bar and the copper har, 3 3/4' conventional and 5' all-pass vibration absorber,packer sliding perforation units, fisher of bar etc. in the supporting equipment system. The remarkable economic and social benefits are obtained in the applications in many oilfields
