The Study Of Fuyu Oil Layer’s Geologic Modeling Of 84-6 Oilfield Block Of Chaoyanggou Oilfield

Block 84-6 is located in the territory of the DPRK Zhaozhou County, Heilongjiang Province, is located in the north wing stand Tuen anticline structure on the block, it is a low porosity- extremely low permeability reservoirs, small area for exploration wells and sparse commentary, well control low level, the relative lack of geological information on subsurface geological knowledge is weak, sandstones, sand size and distribution characteristics is not clear; low reserves, tight reservoirs, development of poor results.By contrast stratigraphic division, sedimentary microfacies research, calculation of reserves, the establishment of three-dimensional structural model of the study area,sedimentary facies model and phased Zodiac model, and model and calculation of reserves of crude, and then to reservoir characterization study area for late reservoir simulation and remaining oil development potential to provide a basis. Carry oil group of single sand body prediction, determine slots and stacking cases each single sand body spatial distribution characteristics and various sand between the completion of the small micro-layer deposition phase diagram, complete geological modeling based on reservoir prediction.In Petrel environment, combined with well-seismic data to build the structural model of the study area, the application of well and seismic technology, the study area 197 wells team divided sedimentary unit comparison. Its flat grid nodes: 60706 flat grid size: 25 m × 25m;build phase model and property model 41 sedimentary units in the infrastructure model, the target area in the geological model established on the basis of the target roughened block model, the plane grid size: 50 m × 50 m.
