摘　　要：应用泊松比法和水力压裂经验法研究破裂压力界限,从超破压注水和形成有效驱替压力梯度两方面论证了提压下限;通过理论计算、试井分析及现场试验确定了井层合理注水强度,确定了建立有效驱替压力梯度的合理压力。提压后,吸水剖面得到改善,对应采油井大面积见效。为同类型油田开发后期注水结构调整提供依据,补充完善了特低渗透油田注水开发配套技术。By using Poisson＇s ratio and penetrating fluid method, fracturing pressure limit is studied. Lower limit of increasing pressure is demonstrated in terms of water flooding with extra fracturing pressure and effective displacement pressure gradient. Based on theoretical calculation, well test analysis and field experiment, flooding intensity of well later and reasonable pressure of effective displacement pressure gradient are determined. Intake profile has been improved and effective results have been got after increasing pressure, which provided bases to water -floodhag structural adjustment in late development of same type oilfield and flooding development matching technology of ultra low permeability oilfield has been improved.
