一套能用于井下油管内实现安装和回收可取式的YZ—38—224与JZ—38—508绳索式震击器和51mm、63mm震击释放工具,最近由四川石油管理局钻采工艺研究所研制成功,并通过了局级鉴定。胜利、青海油田和四川气田,先后在井下油嘴节流开采、柱塞清蜡、投捞式气举等施工作业中,用该套工具进行了33井次现场试验。试验表明,震击器能产生所要求的震击力,与释放工具配套使用,无需起下井内的管柱,便能灵活、安全、可靠、快速地完成井下工具的提、捞、释放绳索作业,减少了吊灌压井作业对产层的伤害,显示了工艺的科学性和经济性。
A set of YZ-38-224 and JZ-38-508 rope jars and 51mm, 63mm shock release tool that can be used for downhole tubing installation and recovery are the most recent by the Sichuan Petroleum Administration Bureau of drilling technology research The successful development, and passed the bureau-level appraisal. Victory, Qinghai Oilfield and Sichuan Gas Field successively carried out 33 field-level field tests with such tools in such construction operations as downhole oil nozzle throttling and mining, plunger wax removal and gas-lift fishing. The tests show that the jar can generate the required shock force and be used with the release tool to accomplish the flexible, safe, reliable and rapid downhole tool lifting without releasing the string in the well, releasing the rope operation , Reducing the damage to the pay zone caused by the irrigation and killing operations, showing the scientific and economical process.
