PARAMETER MODELING OF LOW PERMEABILITY TIGHT RESERVOIR BASED ON FINE LITHOFACIES CONSTRAINT:A Case Study of C-812 Tight Sandstone Reservoir in No.92 Wellblock of Honghe Oilfield
摘要
Abstract
The Honghe Oilfield in Ordos Basin is a kind of lithologic reservoir with low porosity and ultra‐low permeability, among which the C‐8 reservoir mainly develops two types of sedimentary microfacies, including underwater distributary channel and interdistributary bay of braided‐river delta front. The reservoir parameters of the former vary widely with strong heterogeneity,and the spatial distribution cannot be adequately characterized by conventional single sedimentary facies‐controlled modeling. To accurately describe the reservoir parameters and distribution characteristics,taking the C‐812 tight sandstone reservoir in No. 92 wellblock of Honghe Oilfield as an example,the reservoir parameter modeling method based on fine lithofacies constraint is applied to establish the 3D geological model on the basis of geology,core and well logging data. That is,first using the sedimentary facies development pattern constraint to built sedimentary microfacies model,then subdividing the lithofacies of underwater distributary channel microfacies, and establishing the lithofacies model under the dual control of sedimentary microfacies model and probability bodies of different lithofacies,and finally the reservoir parameter models based on lithofacies model constraint. The results show that the reservoir parameter model established by this method is highly reliable and consistent with geological understanding,which provides accurate geological models for reservoir numerical simulation and basis for further development adjustment in the study area.关键词
