摘要
辽东湾绥中36-1油田东营组三角州砂体具有完整的埋藏成岩作用序列。该砂体主要孔隙类型为早期碳酸盐胶结物和可溶性颗粒溶解形成的次生孔隙.由沉积相和成岩作用研究表明,不同沉积相其埋藏成岩的孔隙演化途径不同.孔隙几何学形态和自生粘土矿物类型是评价储集性的重要参数.高岭石丰度指数高、由粒间孔和颗粒溶孔组合的支流河道和河口坝微相物性最好.
Deltaic sand reservoir of Dongying formation of SZ 36-1 oil field possesses a complete sequence of buried diagenesis,The main porosity type of it is secondary which results from dissolution of the early carbonate cement and unstable grains,Study of depositional facies and diagenesis indicates that various facies have taken different evolution path during the history.In regard to reservoir evolution,pore geometry and types of authigenic clay are im- portant factors.It is concluded in the paper that microfacies of distributary channels and channel mouth bars which are rich in kaolinite and have developed intergrain and intragrain pores are of best lithophysical properties.
