基于压汞法的成庄井田3号煤孔隙特征研究
|
摘要
煤孔隙特征是煤储层物性特征的关键参数之一,控制着煤层气赋存、运移和煤层气开发效果。采用压汞法对成庄井田3号煤孔隙进行了深入和系统研究,结果表明:成庄井田3号煤孔隙形态基本一致,以一端封闭的不透气性孔隙为主;煤中过渡孔和微孔最为发育且所占比例较高,煤总孔隙面积和比表面积较大;煤中有效孔隙不甚发育,煤的孔隙度较低;孔隙大小对孔容控制显著,孔隙越大煤的孔容越大,反之亦然。
Coal pore characteristics is one of the key parameters of the physical properties of coal reservoirs,controlling the occurrence and migration of coalbed methane and the development of coalbed methane.The author conducted an in-depth and systematic study on the pores of No.3 coal in Chengzhuang Mine Field by mercury intrusion method.The results showed that the pore morphology of No.3 coal in Chengzhuang Mine Field was basically the same,and the airtight pores closed at one end are mainly.The transition pores and micropores in coal were the most developed and the proportion was high.The total pore area and specific surface area of coal were large;the effective pores in coal were not developed,and the porosity of coal was low.The pore size controlled the pore volume significantly,and the larger the pore size,the larger the pore volume of the coal,and vice versa.
