Reservior Heterogeneou And Opeimization Of Major Reservoirs In Shasan Formation Of Damintun Depression

The article is theoretically based on high-resolution sequence stratigraphy, reservoir geology, reservoir sedimentology,reservoir well logging geology, exploration geology and exploration seismology etc. On the basis of logging data, combined with seismic, logging and core data, the paper applied both rich dynamic and static data which provided by dense well spacing in maturing field during later stage of exploitation as well as sedimentary process analysis, well logging analysis method on the sedimentary unit subdivision and comparison, reservoir sedimentary and reservoir heterogeneity characterization of delimitation sand channel bar of fault-anticlinal oil-bearing structure 84-An 12 block in block sag Daming tun sag structural zone in Liaohe field. Specific study Of micro-structural characteristics, sedimentary facies, reservoir characteristics,oil and gas distribution, oil and water movement's main characteristics and patterns of distribution of remaining oil, Re-calculation of geological reserves, the remaining oil distribution forecast, calculate remaining oil reserves, Evaluation capacity and the small layer of water capacity, Through numerical simulation, to determine residual oil saturation distribution, forecast the development trend, mining reservoir potential, made comprehensive recommendations reasonable or appropriate measures for the block.
