| 摘 要： | 普光地区上三叠统须家河组地层具有较大的勘探开发潜力,根据岩石特征及测井相对该地区须家河组沉积相类型、储集空间类型、储层物性特征以及影响储层的因素等分析表明,家河组主要发育辫状河-三角洲及湖泊沉积,并可进一步划分为分流河道、水下分流河道和分流间湾等微相;储层主要表现为低孔-低渗、特低孔-特低渗,储集孔隙空间为粒内溶孔、残余粒间孔、粒间溶孔,裂缝-孔隙型是主要的储集类型;储层储集性能主要受沉积微相和成岩作用控制。

| Abstract: | Braided fiver-delta and lacustrine facies which may be subdivided into distributary channel microfacies, subaqueous distributary channel microfacies and interdistributary channel microfacies were developed in the Upper Triassic Xujiahe Formation of in the Puguang region. Reservoir rock is characterized by low porosity and low permeability. Reservoir space includes intragranular solution pore, intergranular solution pore, relic intergranular solution pore. Reservoir belongs to fractured-porous type. Reservoir character is controlled by microfacies and diazenesis. |
