摘　　要：低渗油气田的油气资源正在成为世界未来能源和经济发展的动力，而这些致密储层中的油气主要得通过水力压裂才能实现经济开采。水力压裂技术机理复杂、影响因素众多，所以对压裂作业增产效果进行评价变得尤为重要。目前国内外用于裂缝检测技术的仪器种类较多，且在仪器性能、优劣势方面存在不同程度差异，其中地面测斜仪和井下微震监测被认为是当前最先进的裂缝检测技术。利用微地震压裂监测结果可以分析压裂井的裂缝展布特征、验证压裂施工效果，从而使传统解释方法的准确性得到提高：The resources of low-permeability oil ＆ gas fields are becoming the power of the globe future energy and economy development. Those oil ＆ gas deposited in tight reservoirs can only be produced economically through hydraulic flacturing techniques. As the mechanism of hydraulic fracturing techniques is ve~ complicated due to many influencing factors, the evaluation of the post-frac and its result is getting very important. Presently their is a variety of fracture detection or monitoring instrument and devices at home and abroad with different features anti advantages, among which both surface tihmeter and subsurface micro-seismic monitoring are deemed to be the most advanced means for fracture detection. Characteristics of fracture extension can be analyzed, and the effect of fracturing operation in fractured wells can be verified with the result of mieroseismic fracture monitoring, and sequentially the accuracy of traditional interpretation approaches can be improved.
