Dusek 3井采用双管柱无油管完井时井底高压使常规定向射孔中的机械和电动定向工具无法使用。本文介绍了钢丝传输定向射孔技术在Dusek 3井的实施过程。钢丝下入射孔管柱 ,射孔管柱底部的定位销与完井管柱内的定向短节相配合对射孔管柱进行定向。可通过伽玛测井测量射孔管柱上的三个方向不同的放射性标记 ,以此检验射孔枪是否定向准确。实践证明这项技术是成功的。 Bottomhole high pressure in Dusek 3 wells using double-column, tubing-less tubing makes the mechanical and electrical directional tools in conventional directional perforations unusable. This article describes the implementation of the directional transmission of steel wire to the Dusek 3 well. Under the steel wire, the positioning pin at the bottom of the perforating column and the perforating column cooperates with the directional short section in the completion column to orient the perforating column. Gamma well logging can be used to measure three different radioactive labels on a perforating string to verify that the perforating gun is oriented correctly. Practice has proved that this technology is successful.
