摘要
偏心分注验封及分层压力测试技术,能够在正常注水状态下同步测试录取偏心分注井分层水嘴压力降落和流量变化结果,通过分层吸水量进行压降曲线分析,准确判断各层段吸水能力变化情况,能够实现分层注水、分层测压,达到调整注水井层间矛盾。通过对偏心分注井投捞测配状况及存在的问题进行分析,对该技术进行改进完善,使偏心分注管柱在油田得到广泛推广和应用。
Technologies of eccentric separated injection with seal inspection and pressure test to separated layer,can test and acquire pressure drop of the separated nozzle and result of flowing change to eccentric separated layer of injection wells under normal condition of injection status. By analyzing the pressure drop curves from stratified water volume,changes in water absorption capacity of each interval are determined accurately,and that of stratified injection,layered testing is achieved to adjust layer contradictory of the injection wells.Through analysis of situations and existing problems of the cast,fishing,measured and dispensing for eccentric separated injection well,the technology is improved which lets the eccentric dispensing strings to be promoted and applied widely in the oilfield.
