内容简介
本书以沉积岩石学、石油地质学、储层地质学、开发地质学和国内外气藏描述等近期新研究理论为指导，综合应用钻井资料、测井资料、录井资料、测试资料、气藏动态开发等资料，对新场气田沙溪庙组JS22气藏地层、构造、沉积相、储层特征、储量分布、动用状况及气藏的开发调整潜力进行综合研究，在三维地质建模的基础上进一步找出JS22气藏未动用储量的分布规律。研究表明，沙溪庙组JS22气藏主要为辫状河三角洲沉积，发育三角洲平原亚相，主要沉积微相包括分流河道、天然堤、决口扇、分流间湾。JS22为中-低孔隙度、超低渗致密储层，层间渗透率非均质性较弱。在三维地质建模的基础上，对气藏储量进行复算，上沙溪庙组JS22气藏储量为180.68×108m3，其中JS22-1、JS22-2气层储量分别为47.05×108m3和133.63×108m3，依据储能系数和地层系数把储量划分为Ⅰ类、Ⅱ类、Ⅲa类和Ⅲb类共4种类型。JS22气藏目前动用储量约136.74×108m3，储量动用程度为74.94%，主力区域内目前采出程度大部分在30%以下，后期未动用储量区建立水平井井网进行全面开发的潜力较大。
