摘　　要：针对丛式井组开发分注管柱有效期短、分注井测调成功率及效率低等问题,开发了桥式同心分层注水技术。为了完善配套桥式同心分注技术,以桥式同心配水原理为基础,研制了桥式同心分层压降测试仪器,制定了分层压降测试方法,解决了桥式同心分注井无法测试分层压降的难题,实现了多层分注井双卡井下单层压力直测。该技术在长庆油田现场试验10井次,最大井深2 536 m,最大井斜35.8°,试验成功率100%,应用效果良好。该仪器的研制成功极大地提升了桥式同心分层注水技术的适应性,更进一步掌握了油藏分层压力情况,有利于指导油藏动态调整。To address the issues ol separate layer injection tubing for cluster well production l ike short operat-ing period and low success rate and low efficiency ol testing and adjusting, a bridge concentric separate layer water injection technology has been developed. To improve the developed technology, based on the principle ol bridge concentric water distribution, a bridge concentric separate layer pressure testing device has been developed, and pressure drop testing method has been established to address the separate layer pressure drop testing in the bridge concentric separate layer injection well. Therefore, downhole dual packer single-layer direct pressure testing for sep-arate layer injection well has been achieved. The technology has been tested in Changqing Oilfield for 10 well times with the maximum well depth ol 2 536 m, the maximum well inclination ol 35. 8.and the success rate ol 100%, presenting great application performance. The successful development of the device has greatly improved the adapta-bility ol the bridge concentric separate layer water injection technology to acquire more knowledge ol reservoir pres-sure so as to guide the dynamic adjustment ol the reservoir development.
