摘要
页岩气藏勘探开发过程中数值模拟技术的应用是一个崭新的研究课题,目前国内外均无成熟的经验做法。本文调研了国外页岩气藏数值模拟技术研究方面的最新进展,以期对我国该方面的研究工作提供参考和借鉴。调研结果表明,对天然裂缝和水力压裂裂缝组成的复杂裂缝网络系统和页岩气渗流特征的准确表征是做好该类气藏模拟的关键所在,而天然裂缝渗透率、基质—裂缝耦合因子、水力压裂裂缝参数对页岩气藏产能模拟敏感性最强,可作为历史拟合的可调参数。通过页岩气藏数值模拟,可对页岩气井生产动态预测、剩余储量分布、页岩气藏加密钻井、水力压裂及二次压裂施工等提供有益的参考。
Shale gas reservoir simulation technology is a new research project in the shale gas exploration and development, there is no experienced knowledge to be referred to from home and abroad. Studied the newest foreign progress on the shale gas reservoir simulation, wish that this work will be helpful to China＇ s relevant research. It is the key to simulate this kind of gas reservoir that the shale gas seepage characteristic and the complex fracture cracks network system composed of natural cracks are precisely characterized. The Natural fracture permeability, matrix-crack coupling factor and hydraulic fracturing fracture parameters are the most sensitive to the shale gas reservoir deliverability simulation, which could be taken as the adjustable parameters in history matching. The shale gas numerical reservoir simulation can provide the beneficial reference for predicting the shale gas well production performance, residual reserves distribution and shale gas reservoir infill drilling, hydraulic fracturing and secondary fracturing operation.
