摘要
在前人研究的基础上,本文主要从储层岩石学特征、储层孔隙特征和储层平面非均质性(主要是孔隙度和渗透率)这几个方面对绥靖油田三叠系延长组长7储层进行综合研究,研究表明:该区长7储层属于中-低孔、低渗储层,岩石类型主要为长石砂岩和石英砂岩,岩屑含量较多;填隙物以高岭石等粘土矿物为主;喉道分布较均匀,以中细喉为主;Ⅰ类(好)储层主要分布在分流河道沉积微相。
On the basis of previous studies,this article mainly has a comprehensive study from the reservoir rock characteristics,reservoir porosity characteristics and reservoir plane heterogeneity(mainly porosity and permeability)about Chang 7reservoir of Suijing oilfield,Studies have shown that:Chang 7reservoir belongs to low porosity and low permeability reservoir,rock types are mainly feldspathic sandstone and quartz sandstone,The main interstitial materials areclay minerals such askaolinite.Throat is mainly middle and fine roar.Ⅰtype(good)reservoirs are mainly distributed in the distributary channel sedimentary microfacies.
