摘要
从页岩气藏气体赋存方式和流动机理、气藏建模方法及数值模拟理论研究和实际应用3个方面阐述了国内外页岩气藏数值模拟技术的研究进展,为该技术的深入研究提供参考。最后,对页岩气藏数值模拟研究进展进行总结,认为存在4个有待于改进和研究的问题:①完善储层模型以考虑有机质的影响;②需要阐明单相气体解吸附、扩散和渗流过程的运移规律和主控因素,并建立气、水两相流动数学模型和数值模型;③天然裂缝和压裂诱导裂缝的准确建模是页岩气藏数值模拟的关键,实际应用中应综合考虑其他监测技术的结果;④针对页岩气藏数值模拟,还需要形成相应的标准和规范,以便更好地指导该类气藏开发。
This article expounds on the recent advancement of the technology all around the world through the following three aspects:shale gas occurrence and flow mechanism ,gas reservoir modeling ,as well as theoretical study and applica-tion of numerical simulation .It suggests that four issues remain to be improved and further probed:①Improving reservoir modeling to take the effect of organic matte into consideration;②Expounding more on flow mechanism and main control-ling factors of single-phase gas desorption ,diffusion and percolation ,and establishing mathematical model and numerical model for two-phase ( gas/water ) flow;③Understanding the importance of accurate modeling of natural and induced frac-tures to shale gas reservoir numerical simulation ,and combining related results of other detecting techniques in practical application;④Establishing corresponding standards and norms for shale gas reservoir numerical simulation .
