摘要:
 常规钢丝脱挂工具压力测试时，单一依靠地面绞车确定深度，无法实现井下脱挂器深度精准控制;且依靠电池提供动力源，存在电池爆炸及电量不足等风险。电缆投置脱挂工具采用电缆下入方式，地面直流电提供动力源，脱挂工艺实时释放，内部无单片机控制程序；用GR仪器进行校深，实现深度精准控制；电机开关控制电路，解决了GR仪器与脱挂器电机供电不匹配的问题；内部采用高温高压器件，满足175 ℃测试需求。在大港油田某井压力测试施工中应用该工具，实时判断井下定位短节释放情况，工艺成功。该工具操作直观，节约测试成本，具有广阔的应用前景。
Abstract:
 When the conventional steel wire disassemble tool is used for pressure test, it cannot determine the accurate depth downhole decoupler only relying on the ground winch; In addition, it also has the risk of battery explosion and insufficient power because of the power supply from the battery. Cable casting and fishing disassemble tool uses cable to run in hole, and the ground DC power is used to provide the power source. The disassemble technology is released in real time, and there is no singlechip control program inside; In addition, GR instrument is used for depth correction to achieve accurate depth control; The motor switch control circuit solves the problem that the GR instrument does not match the power supply of the disassemble tool motor; High temperature and high voltage devices are used to meet the test requirements of 175 ℃. The tool is applied in the pressure test of a well in Dagang Oilfield to judge the release of downhole positioning nipple in real time, and the process is successful. The operation of the tool is intuitive, and the test cost can be saved, which has a broad application prospect.
