摘要
Abstract
The upper carboniferous benxi formation in Yichuan area of the Ordos Basin is mainly composed of barrier and lagoon sedimentary and developing medium-coarse sandstone reservoirs.The Benxi sandstone reservoirs are mainly composed of secondary dissolution pores and intergranular pores by the identification of core castings thin sections, capillary pressure data and porosity and permeability data.The average displacement pressure is 0.51MPa, the mean value of throat median radius is 0.926μm, and the porosity and permeability are low, which belongs to the low porosity and low permeability reservoir.On the basis of core test and analysis, combined with logging interpretation results and gas test results, the reservoir classification and evaluation criteria are established.It holds that the reservoir stratum of Benxi formation is excellent totally, and parts worse.关键词
