RESEARCH AND APPLICATION OF TECHNOLOGY COMBINED INNER BLIND HOLE PERFORATOR AND TUBING PUMP

介绍了内盲孔射孔器与管式泵联作技术的选泵标准、起爆方式、原理和流程以及内盲孔射孔器的研制。该技术是将油管输送射孔与采油管柱结合起来,使射孔完井与新井下泵一趟管柱完成,在下完抽油杆之后,密封井口,采用油套环空加压引爆射孔枪的方式,射孔后立即启动抽油机,进行采油。该工艺可提高射孔完井效率,又可预防井喷事故发生,减少作业次数和井喷压井所带来的水泥车和压井液费用,同时减轻了工人劳动强度。在大庆油田采油三厂N5-9-B52井的现场应用见到了明显的效果。

This paper introduces the criterion of selecting pump, detonation mode, principle and action of inner blind hole perforator and tubing pump joint technology. A joint technology which take TCP combine with production pipe string has been developed to complete perforating and running pump in one trip. After running pumping rod or sucker rod, the wellhead is sealed, and then the perforators are detonated through increasing pressure in the annular. As soon as the perforating operation is finished, the pumping rod is started for drainage and oil recovery. This technique not only increases perforation completion efficiency, but also simplifies operating procedures and cuts down costs and lighten the labor strength of workers. It is successfully used in Well N5-9-B52 in No.3 Oil Production Factory, Daqing Oilfield and good effect is obtained.
