摘要
从递减曲线方法、产能解析公式以及数值模拟方法等三方面阐述国内外页岩气藏产能评价方法的研究进展,通过总结对比指出各方法亟待发展与改进的问题:递减曲线方法应考虑分阶段研究,即考虑组合模型;产能解析公式应考虑中国页岩气藏地质条件进行模型研究;数值模拟方法应主要发展复杂裂缝网络的地质建模等技术,实际开采中综合考虑其他监测技术。
From the decline curve method,capacity analytic formula and numerical simulation method,the research progress on shale gas reservoir capacity evaluation both at home and abroad has been carried out.Through summarization and comparison,the development and improvement of these three methods have been put forward.As for decline curve method,stage research and combination model should be considered.As for capacity analytic formula,shale gas reservoir geological conditions should be considered in model study.As for numerical simulation method,the geological modeling techniques should be considered in complex fracture network.In practical production,comprehensive monitoring techniques should be taken into consideration.
