摘要

在我国煤、油、气共生盆地中,常规石油天然气与非常规煤层气能否实现共采是近期关注的热点问题。基于济阳坳陷惠民凹陷外围不同煤级煤样吸附性的物理模拟,结合石油天然气探井实测的温度和压力资料,对该区深部(2 000 m以深)煤层的含气性进行了预测,结果表明该区深部气煤―肥煤的原位含气量在5.0 m3/t左右。

Abstract

It is a hotspot question that how are normal oil and gas resources developed with unconventional coalbed methane resources at the same time in the basin with coal,oil and gas resources. Based on physical simulation of adsorption of different coal rank samples from adjacent coal mine of Huimin depression,and combined with measured data of temperatures and pressures of oil and gas wells, deep coalbed methane contents are predicted. The results show that coalbed methane contents of gas coal to fat coal in situ are about 5 m perton.
