沁水盆地南部煤层气储层特征及可采性研究

CBM Reservoir Features and Recoverability Study in Southern Qinshui Basin

根据沁水盆地南部的樊庄、郑庄两个区块的煤层气勘探开发资料,以及吸附性、渗透性测试结果,分析了研究区储层的物性特征,采用五指标法和模糊数学评价法对两区块可采性进行系统评价。研究认为:两区块所处的地质构造背景相似,均属于Ⅰ类资源大区,但因两者在储层埋深、储层压力、含气性等方面存在一定的差异性,使得樊庄区块煤层气的开发条件要优于郑庄区块。

Based on CBM exploration and exploitation data in the Fanzhuang, Zhengzhuang blocks in southern Qinshui Basin, and test？ed results of adsorption, permeability, analyzed study area reservoir physical properties and carried out systematic assessment on recov？erability of the two blocks through five indices method and fuzzy mathematics evaluation method. The study has considered that：the tec？tonic setting of two blocks is similar, belongs to category I region, but certain difference existed on aspects of reservoir buried depth, pressure and gas-bearing property made the exploitation condition of Fanzhuang block is superior to Zhengzhuang block.
