摘要
塔木查格盆地是典型的低渗透性储层,压裂改造是目前最重要的增产方式之一。在实际工作中,压裂选层是面临的一个重要难题,为进一步提高压裂可行性和有效性,对该区不同测试曲线形态、压力特征以及储层导流能力进行分类和数理统计研究,分析测试成果及录井测井资料与压裂效果之间的内在关系,确定了压裂选层原则,建立了以电测解释参数为基础的措施效果预测方法,为压裂选层提供了依据。经过42个试油层实际应用,压裂效果预测准确率达到了71.73%,有效提高了压裂有效率。
Tamuchage Basin is a typical low permeability reservoir, and in which fracturing is one of the most important methods to enhance production. In practice, fracturing zone selection is a key problem facing engineers to further improve the feasibility and effectiveness of fracturing. The various testing curves in this area, the pressure characteristics and reservoir conductivity were classified and statistical researched; and then the intrinsic relationship between testing results, logging information and fracturing effect have been analyzed to determine the fracturing zone selection principle; finally, measurement effect prediction method based on electrical logging explanation parameters has been set up to provides the evidence for fracturing layer selection. 42 layers practical application had launched, and the accuracy of reservoir fracturing effect prediction reached 71.73%, which effectively improve the efficiency of fracturing.
