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。本文利用剩余油研究结果,结合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。
Ma Chang and Qiao Kou Oilfields belong to low permeability, multi-reservoir and heterogeneous complex fault block reservoirs and enter the middle and late stages of waterflooding. Due to the combined mining and acquisition, Class I reservoirs are severely flooded. In order to improve this situation, the application of low permeability fracturing technology to fully tap the production potential of Ⅱ, Ⅲ oil layer. In this paper, the remaining oil research results, combined with the geological conditions and development of fracturing wells to determine the level of well selection standards for fracturing well, the application effect is significant.
