摘要
通过岩心观察、薄片鉴定、物性分析等手段,研究了巴麦地区石炭系小海子组灰岩储层的岩石类型、孔隙空间类型、物性特征和影响因素。研究结果表明,巴麦西段石炭系小海子组储集空间以粒间溶蚀孔隙为主,伴生晶间孔和微裂缝。储层物性受高能颗粒滩相控制,沿裂缝发育的白云岩交代作用促进了溶蚀作用的进行,改善了储集物性。
Type of reservoir rocks,pore space types,physical properties and affecting factors were studied through core observation,section analysis and physical property analysis.The result shows that the main reservoir space is inter-granular dissolution pore space and its associate inter-acrystalline pore and fracture in carboniferous Xiaohaizi Formation.The study proves that high-quality reservoir is controlled by the high energy beach sedimentary facies and dolomitisation.It can ensure enhancing dissolution along the fractures.The reservoir physical property is improved.
