| 摘 要： | 苏75-70-6H井是依靠国产技术完成的规模最大的裸孔水平井压裂井，水平段南北走向。微地震监测给出了每段压裂裂缝是否形成及形成位置、形态，指导压裂施工继续进行；监测出压裂液漏泄段，预警出现砂堵的可能；保证了压裂施工的成功，证明了国产井下工具完全可以实现多段压裂改造。监测结果准确反映指导了压裂施工过程。

| Abstract: | Well Su 75-70-6H is the largest open hole horizontal well fracturing built by domestic technologies. Orientation of horizontal section is north-south. Microseismic monitoring shows whether fractures are generated, locations and patterns of fractures, and further provides a guide for fracturing operations; monitoring can also identify location of possible fracturing fluid leakage, provide early warning of sand blocking and help evaluate the effectiveness of stimulation. It proves that domestic manufactured fracturing downhole tools can be used.The result of microseismic monitoring accuratly reflect the operation process,as well as guide it. |
