陆梁油田储层成岩作用与孔隙演化
Diagenesis and Pore Evolution of Reservoir in Luliang Oil Field
-
摘要: 对陆梁油田白垩系及侏罗系储层成岩作用过程的研究表明,储层的孔隙演化主要与压实作用、溶蚀作用和胶结作用等有密切关系。压实作用、石英次生加大和高岭石的后期充填作用是使孔隙遭受破坏的主要成岩作用类型,长石和碳酸盐矿物的溶蚀作用是形成次生孔隙的主要成岩作用类型。各种成岩作用的时空配置关系控制着孔隙的发育程度;储层孔隙发育具垂向分带性,在纵向上发育一个次生孔隙带,这对预测本区储层物性的空间分布具有重要意义。Abstract: The study on the diagenesis course of Cretaceous and Jurassic reservoir in the Luliang oil field indicates that evolution of reservoir pores is closely related to compaction,solution and cementation. Compaction,quartz secondary enlargement and kaolinite an aphase-infilling are main diageneses to damage pores. The solution of felspar and carbonate minerals are the chief diageneses to form sencondary pores. Space-time configuration of various diageneses controll the development of pores. Development of reservoir pores in vertical zoning formed a secondary pores belt. So,it is significant to forecast spatial distribution of the reservoir physical properties.
