| This paper takes the basic pirnciple and technical method of reservoir sedimentology,petroleum geology as a guide to the core description, detailed analysis of indoor analysis andsystem mapping as the foundation, through to the top surface structural characteirstics, thesublayer sedimentary microfacies fades belt distribution characteirstics and seepagecharacteirstics of sand body distirbution, oil layer thickness distirbution, the top surfacestructure and reservoir thickness and permeability and thickness of sand body three are theoverlapping distribution, reservoir petrology, pore structure, physical distribution and reservoirheterogeneity research, to evaluate the reservoir characteirstics of Chang4+5and Chang6reservoir group of each layer, combined with the oil test, production test summary data, oiland gas enrichment rules, then the evaluation and selection of favorable exploration target areaof each layer. Through the research of oil production plant and its adjacent area expeirence ofmany years of development, formulate reasonable development scheme. |
