摘　　要：濮城油田沙三中油藏低孔低渗,压力恢复慢,利用常规测压技术测得油井压力低、注水井压力高,难以测得符合实际的压力。经讨论分析,选择了油井二流量试井,注水井压降试井的方式替代常规测压。实验结果表明,油井压力(较常规测压)平均至少提高4.49MPa,注水井压力平均下降11.0MPa。经推广实用,效果显著。That low porosity and permeability in middle sand 3 reservoir, Pucheng oilfield and slowness of pressure build-up makes the pressure in oil well recorded by conventional pressure testing technology low and that in injection well high which is difficult to conform actual pressure.By discussing and analysis,double flow testing in oil well and down pressure testing in injection well are selected. The result illustrates that pressure in oil well (comparing to conventional pressure testing) increases 4.49 MPa at least averagely.
