新立地区嫩三段储层非均质性及其影响因素分析

针对新立地区嫩三段各层位储层岩石学、物性、非均质性、微观孔隙结构等特征认识不清的问题，综 合运用岩心薄片、扫描电镜、压汞曲线及测井等资料，对该区储层宏观非均质性（平面、层内、层间）和微观 非均质性（孔隙）进行了研究。结果表明，新立地区嫩三段储层呈现强非均质性特点。同时，分析了该区储 层非均质性的影响因素，认为沉积微相从根本上控制了储层非均质性的形成，而成岩作用引起的一系列 变化则使储层非均质性增强。

Reservoir heterogeneity and influencing factors of Nen 3 member in Xinli area

In view of the problems that reservoir petrologic characteristics,physical properties,heterogeneity and microscopic pore structure characteristics have not been researched clearly,by comprehensive application of the data of core slices,scanning electron microscope,intrusive mercury curve and well logging,this paper studied the macroscopic and microscopic heterogeneities of the reservoir.The result shows that reservoir of Nen 3 member in Xinli area has strong heterogeneity.The influencing factors of heterogeneity were analyzed.It is considered that sedimentary microfacies fundamentally control the formation of reservoir heterogeneity,and a series of changes caused by diagenesis can enhance the reservoir heterogeneity.
