摘 要：The occurrence of hydrocarbon migration in petroliferous basins depends on the balance of driving force and resistance of carriers,which restricts mostly the quantity and positions of hydrocarbon *** driving forces of hydrocarbon migration have been quantitatively studied, whereas the migration pathways and carriers were only quaUtatively discussed up to *** a compound hydrocarbon carrier system and quantitatively characterizing its transport capability are significant for understanding the dynamic process of hydrocarbon migration and revealing the hydrocarbon accumulation *** has become an innovatory trend and also a difficult topic in study of hydrocarbon *** this article,a method is described for using displacement pressure to quantitatively characterize the transport capability of the compound carrier system,which composed of sandstone carriers,unconformities and *** the weathered and leached zone rarely developed,the basal conglomerate or transgressive sandstone of unconformities can be treated as part of sandstone *** empirical relationship among core porosity,air permeability,and the pore aperture radius corresponding to a mercury saturation of 10%(r) can be obtained by multiple regression. Using porosity and permeability inversed by seismic data,the displacement pressure of sandstone carriers can be calculated by the empirical relationship and Washburn *** pressure of fault plane can be estimated by the regression formula between fault opening index(FOI) and hydrocarbon column height it can support This method is applied in the eastern part of south slope in Dongying(东营) depression,Bohai(渤海) Bay Basin,China,to quantitatively characterize the transport capability of the compound carrier system of Shahejie(沙河街) *** results have good agreement with data from drilling *** method may be a step further in study of compound hydrocarbon carrier system in petroliferou
