液压式解卡工艺管柱的研究及应用

Research and Application of Hydraulic Technological Casing String for Jam Releasing

摘要:

近年来，葡萄花油田平均每年拔不动待大修的油水井约有40口，采取常规地面解卡机或者应用大修架子处理解卡存在安仝隐患和作业费用高的实际问题，为此开展了液压井卜解卡技术研究，该技术主要由泄油器、液压式井下解卡器、安全接头和打捞工具等组成，通过地面泵车打压来控制井下液压解卡器实施解卡，既可消除安全隐患，又可节约作业成本，在油田开发的中后期具有广阔的应用前景。

Abstract:

There arc almost 40 oil or water wells in which the casing tubes cannol be pulled out in the Putaohua oil field in each of the past few years. It has hidden danger and cosls a lot to use traditional releasing tools or heavy repairing racks to solve the problem. So down well hydraulic pressure jam releasing technique has been researched with oil drain device, down well hydraulic pressure jam releasing assembly, safe joint and fishing tools; the pump truck on thc ground provides pressure for the hydraulic releasing assembly to keep safety and reduce cost. This technology can be widely used in the middie and later period of oil field development.
