辽河油田杜 84块兴隆台油层为超稠油油藏。储层埋藏浅 ,压实程度与胶结程度低且以粘土矿物胶结为主 ,处于早成岩阶段。储层孔隙发育 ,以原生粒间孔为主 ,次为粒间溶孔和裂隙孔。根据铸体图象和压汞曲线获得的孔隙结构特征参数确定 ,该储层孔隙直径大 ,喉道直径中等 ,属大孔中喉道型。因此该储层物性好 ,含油饱和度高 ,是本区的主要开发储层
Lubehe Oilfield Du 84 Block Xinglongtai ultra-heavy oil reservoir. The burial depth of the reservoir is shallow, the degree of compaction and the degree of cementation are low and the clay minerals are mainly cemented, which is in the stage of early diagenesis. The pores of the reservoir are developed mainly with primary intergranular pores, followed by intergranular dissolution pores and fissure pores. According to the characteristic parameters of pore structure obtained from the image of the casting and the mercury intrusion curve, the pore diameter of the reservoir is large and the throat diameter is medium. Therefore, the reservoir has good physical properties and high oil saturation, which is the main development reservoir in this area
