Abstract


Based on the analysis of exploration wells information, seismic data and typical reservoir, research the unconformity structure feature,research the action of unconformity structure in reservoir-forming ,make definite the Unconformity reservoir reservoir-forming mechanism .Establish the forecasting modle of oil-bearing property appraisement,clarify the Unconformity oil reservoir distribute.Weathering difference of sandstones and mudstones in Jiyang Depression resulted that the unconformity structure mainly plays the role of screening and controlling traps, which is difficult to from continued lateral transportation bed, so unconformity is not the main pathway of long distance oil and gas migration, but plays role of vertical or horizontal transportation in parts of area. Based on the analysis of unique feature in statigraphic trap and stratigraphic reservoir, according to analyzing the reservoir-forming dynamics in oil-gas migration, the main controlling factors of oil-bearing property quantify appraisement in statigraphic trap in Jiyang Depression are determined ,which include migration distance from oil source to thraps, dip angle of transportation layers,capillary pressure difference between cap formation and reservoir. according to analyzing relationship between these factors and oil-bearing property,symptomatical parameters of factors are determined. Based on the analysis angle factor and oil-bearing property,the wirter establishs quantify appraisement ways in oil-bearing property of reservoir physical property lower limit and oil-bearing column height in statigraphic trap of continental downfaulted basin in Jiyang Depression by multiple regression.Practices proves that the quantify appraisement mode maked to quantitatively predicting oil-bearing property of statigraphic trap.
