Reservoir heterogeneity and influencing factors of Nen 3 member in Xinli area
Online published: 2012-12-20
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.
