成庄井田西部15号煤储层物性对煤层气井产气量影响研究
|
摘要
基于成庄井田西部15号煤储层物性资料和煤层气生产资料,开展了煤储层物性对煤层气井产气量影响研究。结果表明:煤储层物性对煤层气产出特征和煤层气井产气量具有重要影响,不同的煤储层物性参数对煤层气井产气量的影响和作用机理各异。煤层厚度越大、煤层气含量越高,煤层气资源量、资源丰度及含气饱和度越高,有利于煤层气井高产和提高累计产气量;煤储层压力、煤层渗透率越高,越有利于驱动煤层气渗流高效产出、煤层气井高产和提高采收率;煤的高变质,提高了煤的孔渗性、吸附性和煤层气储集性能,有利于煤层气井高产稳产。但延迟了煤层气井产气高峰期时间,对缩短煤层气开发周期亦不利。
Based on the physical data of coal reservoir No.15 west of Chengzhuang Well Field and the means of production of coal bed gas,the influence of coal reservoir physical properties on the gas production capacity of coal bed gas well was studied.The results show that the physical properties of coal reservoirs have important influence on the characteristics of coal bed gas production and the gas production capacity of coal bed gas wells.The higher the thickness of coal seam and the higher the coal bed gas content,the higher the resource amount,resource abundance and gas saturation,which is conducive to the high yield and increase the accumulated gas output of coal seam gas wells.The higher the coal reservoir pressure and coal seam permeability,the more conducive to driving the efficient output of coal bed gas seepage,the higher the high yield of coal seam gas well and the higher the recovery rate.The high deterioration of coal improves the porosity,adsorption,and coal bed gas storage properties of coal,which is beneficial to the high yield and stable production of coal seam gas wells.However,delaying the peak time of gas production in coal seam gas wells is also detrimental to shortening the development cycle of coal bed gas.
