Refined Description Technique Of Oil Reservoirs Of Hei46Block In Daqingzi Oilfield

The work for later guide oilfield development adjustment, improve the effect of reservoirdevelopment, it is necessary to Daqingzi oilfield black46pieces of fine reservoir description,further understanding of the internal structure, block reservoir distribution characteristics anddynamic characteristics, flow unit, reservoir heterogeneity, reservoir distribution, as oilproduction, reasonable development adjustment scheme, using production data, combinedwith reservoir monitoring data, dynamic and static combination, provide the basis for thecorrect selection of mining method.The black block46causes of Gaotaizi reservoir single sand body segmentation andcontrast, build reach because of high resolution sequence stratigraphic framework of singlesand body; in the coring well analysis and logging facies model is established based on planesedimentary development, the short-term sequence cycles microfacies fine research, and thegenetic single sand body is mainly characterized, and then carry out the single sand bodyinternal flow unit, reservoir heterogeneity, oil and water distribution control for anatomicalanalysis, lay solid foundation for the black46blocks of single reservoir connectivity, injectionproduction relation, the rule of waterflooding, oil, water flooding expanding boundary, layerexpansion, maintain oil production. At the same time, through this project research, theestablishment of a set of Daqingzi oilfield reservoir description standard, for later similarproject development to the model and demonstration.
