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。

Abstract

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 application 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 controlling 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 fractures 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.
