摘　　要：二连油田乌里雅斯太凹陷为低孔、特低渗砂砾岩油藏 ,压裂难度大 ,成功率低。经对以往压裂工艺及压裂难点分析 ,进行了优化设计 ,采取了压裂设计与现场实施交叉结合、适时调整 ,台阶式增加排量 ,楔型追加破胶剂 ,强制闭合裂缝 ,多段加砂 ,欠顶替技术等针对性措施 ,使该区块压裂成功率和有效率提高到 10 0 %。Wuliyasitai sag in Erlian belongs to low porosity and super low permeability reservoir that is difficult to be fractured and its success ratio is low. By analysis of the former fracture technology and its difficult points, optimal design has been used and some directed measures, which are crossover connection of design and field operation, timely adjustment, step rate increasing out put, wedge adding breaking agent, forcefully sealed fracture, sectional grave in put, under displacement technology, have been taken and reached the fracture successful ratio and effectiveness to 100 percentage.
