摘　　要：目前已掀起页岩气勘探开发的热潮,针对页岩气的研究主要集中在地质及钻完井,而针对页岩气试井动态方面的研究几乎是空白,研究具一定的先导性。建立了页岩气藏无限导流分段压裂水平井评价模型,讨论了扩散、吸附等参数对压力动态的影响,分析了均质页岩气藏中无限导流分段压裂水平井的压力动态特征,解决了无法确定页岩气藏分段压裂水平井动态参数的难题,形成了均质页岩气藏分段压裂水平井的典型曲线。研究成果可为页岩气藏分段压裂水平井的合理高效开发提供技术支持。At present, there is a shale gas exploration and development boom. However, the study of shale gas are mainly concentrated in the geological and drilling and completion, and the study of shale gas well test dynamic aspects is almost blank. The infinite diversion multi-stage fractured horizontal well in Shale gas reservoir is established evaluation model, which discussed the influence of parameters on the dynamic pressure such as diffusion, adsorption, and analyzed the homogeneous infinite diversion multi-staged fracturing in shale gas reservoir pressure dynamic characteristics of horizontal well, to solve the uncertain problem of shale gas reservoir multi-staged fracturing horizontal well dynamic parameter analysises. It is formed a homogeneous typical curve of shale gas reservoir multi-staged fracturing horizontal wells. Research results provide technical support for the development of shale gas reservoir staged fracturing of horizontal well which is reasonable and efficient.
