| 摘 要： | 通过综合运用地质研究方法,从沉积微相类型及砂体展布特征、储层砂体物性、储层主要成岩作用等方面对鄂尔多斯盆地直罗油田和尚塬区长2油层组进行了综合研究。研究得出长2段储层岩石类型以细粒长石砂岩为主;储层物性较差,微裂缝对改善储层渗透性贡献不明显,属中低孔、特低渗储集体;受沉积相和沉岩作用控制,水下分流河道是形成储层的有利相带;压实作用对储层影响较大,其中机械压实作用和胶结作用破坏性较强,而溶蚀作用为储层建设性的成岩作用。

| Abstract: | We applied the geology research methods to synthetically studied the sedimentary microfacies types,the physical properties,the sand body's features and their distribution trait,as well as the main diagenesis of sand body of reservoirs in Chang 2 reservoirs of Yanchang Formation in the filed of Heshangyuan belongs to Zhiluo oidfiled in Ordos Basin.The type of the rock in Chang 2 reservoirs is mostly fine grain-sized arcose.The physical properties of reservoirs in the research district is bad;the effect of th... |
