摘要

煤储层地层弹性能包括煤基块弹性能、水体弹性能和气体弹性能。对沁水盆地煤储层地层能量的演化发展进行了综合分析,并以关键时刻——燕山中期为界,定量研究了储层弹性能量的地质演化规律,结果表明,煤层气成藏作用与地质历史过程中地层能量场演化息息相关,气藏随着能量系统的动态平衡、聚集散失而发展变化,既可以形成新的气藏,也可能破坏原有气藏,据此认为,评价和预测煤层气成藏的关键是研究区煤储层弹性能量场的演化过程。

Abstract

Stratum energy of coal bed gas reservoirs include coal base, groundwater and gas elastic energies. The evolvement history of stratum energy of the reservoir i
n Qinshui Basin has synthetically been analysed, the geological developing law of its flexibility has been researched in quantitative analysis, taking the key t
ime-middle Yanshanian as limit. The results indicate that coal\|bed gas reservoir forming action is closely linked with the reservoir's energy field of differ
ent geological processes, and has been developed with dynamic balance of energy system and accumulation dissipation of energy. In the whole process, a new gas reservoir may be formed and quondam one be destroyed. Therefore, the key to evaluate and forecast formation of a coal bed gas reservoir is to research the evolvement process of the reservoir's elastic energy field in the research region.
