晋城无烟煤储存游离态CO_2理论容量及其影响因素
|
摘要
深部煤层游离态CO_2理论存储容量随深度增加而变化。基于山西沁水盆地南部煤样测试基本数据,对游离态CO_2煤层存储容量进行计算,并分析其随深度变化规律。基于建立的煤层游离态CO_2存储容量计算模型显示,煤储层游离态CO_2存储容量受孔隙度、含气饱和度、地层温度、地层压力等共同作用的影响。CO_2注入后改变煤储层物性会导致理论存储量有不同程度增加,但存储量增值与实验煤样颗粒大小有关;应力作用下煤储层孔隙度随埋深呈负指数降低规律会显著降低CO_2存储容量,含气饱和度增大会显著增大存储量。
The free CO_2 storage capacity increases gradually with the buried depth in the deep coal seam. The free CO_2 storage capacity was calculated and its change with depth was preliminarily analyzed, based on the tested data of coal samples in the south of Qinshui basin, Shanxi Province. The results show that the storage capacity is affected by porosity, gas saturation, temperature, pressure, etc. The capacity increases with the change of physical properties of CO_2 injected into the coal, but varies with the size of the experimental particle of the coal. The porosity of coal reservoir decreases significantly with depth of coal under effective stress, and the storage capacity of CO_2 is significantly reduced, and also, the capacity increases with the gas saturation.
