川东南地区页岩气的三维地质建模与气藏数值模拟

3D Geoscience Modeling and Numerical Simulation of Shale Gas in Southeastern Sichuan

据最新一期的页岩气资源量统计,中国页岩气的资源量排在世界首位。页岩气绿色革命逐渐兴起,页岩气的勘探与开发越来越多。由于页岩气包含渗流、解析附和扩散等三种流动机理,所以关于页岩气的三维地质建模与数值模拟目前还没有实质性和突破性的进展。本文结合川东南地区五口页岩气井勘探开发情况,对页岩气的数值模拟进行了初步研究,希望能为页岩气藏数值模拟的深入研究提供参考。

According to the latest statistics of shale gas resources, China＇s resource of shale gas ranks the first in the world. As green revolution of shale gas gradually rises, exploration and development of shale gas are increasing. Since shale gas contains three seepage mechanisms, including seepage, desorption and diffusion, geological modeling and numerical simulation on shale gas has no substantive breakthrough. In this paper, combined with exploration and development of five shale gas wells in the Southeastern of Sichuan, preliminary study on the numerical simulation of shale gas was carried out, which could provide a reference for further study on numerical simulation of shale gas reservoirs.
