摘　　要：马厂、桥口油田属低渗透、多油层、非均质复杂断块油藏,进入注水开发中后期,由于合注合采,Ⅰ类油层水淹严重,Ⅱ、Ⅲ类油层动用程度低。为了改善这种状况,应用低渗透油层压裂改造技术,充分挖掘Ⅱ、Ⅲ类油层的生产潜力。利用剩余油研究结果,结舍压裂井层地质条件和开发状况,确定了压裂选井选层标准,应用效果显著。Machang and Qiaokou oilfield belong to low permeability, multiple oil-layer, complicated heterogeneity faulted block oil field whose Ⅰ type of oil layer is water flooded seriously, Ⅱ、Ⅲ types have low producing degree for commingled injection and extraction. to improve this situation, applying reform and fracture tech in low permeability reservoir can excavate producing potential of Ⅱ、Ⅲ type of oil layer. Taking use of result of residual oil research, combing geology condition and development state of fractured well, selecting layer criterion is determined and applied effect is obvious.
