摘　　要：水力冲击压裂化学复合解堵技术是在水力冲击压裂的基础上，用化学解堵剂进一步解除油层堵塞和扩大裂缝间隙，达到增强油层导流能力的油层改造技术。本文介绍了该技术的作用机理、水击压力的确定、施工参数的确定以及现场应用情况。The principles and construction of a downhole hydraulic surge generator for reservoir fracturing are introduced. To improve the efficiency of fracturing and to remove the blockages of organic origin in reservoir formations, a solvent type chemical is used as working liquid in surge fracturing and thus a combinational stimulation technique is established. The technology of this technique and the results of performing such combinational treatments in 9 production wells(5 viscous oil and 4 normal viscosity oil wells) at West Huanxilin Oil field are described.
