Oil Reservoir Fine Description Of Huang 88 Fault Block

According to analyzing and contrasting the drilling and logging data of 51 wells in Huang 88 fault block,stratigraphic correlation standards layer was established.In light of "standard layer controls,cycle contrasts" principle,sand group and sand body of all wells were further divided and correlated.Based on the establishment of stratigraphic correlation profile skeleton,it were divided into 2 oil-bearing series,13 oil-bearing sandbody.Through comparison of E2d12 reservoir groups of oil sandbody,structural map of the top of oil sandbody was drawn,the distribution and characteristics of small scale faults in study area were illustrated.Meanwhile,four oil sandbody culminations and four southeast direction small scale faults were recognized.In view of sedimentary microfacies,rock characteristics,physical characteristics,four-property relationship and heterogeneity,the reservoir characteristics were illustrated.In addition,this article is also focused on the heterogeneity of reservoir that is relatively strong,which is characterized by big difference in layer permeability heterogeneity degree,the development of inside layer,stronger heterogeneity of interlayer.What is more,the plane distribution of oil and gas and the thickness of sandstone is more obvious.This article finished research of micro structure diagram,contrast figure,sedimentary microfacies and sandbody contour map of effective thickness and physical properties,etc.on the basis of dynamic analysis of Huang 88 fault block,contradictions and problems of the blocks in development and production were summed up.Combined with geological research technology and dynamic analysis,the accuracy and rationality of geological knowledge were improved.Reservoir and fluid static fine 3 D geological model describing Huang 88 fault block structure was set up,which provide basis for the further adjustment of Huang 88 fault block.
