Sandstone transport system, as one of the main hydrocarbon transport system, is very important for hydrocarbon migration in Boxing Subsag. Based on the geologic setting, combined with the data of seismic, well drilling cores, formation test, logging and analysis testing, the geological modeling method was applied to establish the 3D isochronous stratigraphic framework model of Es41 in Gao 89 block. Then the sand body distribution map was drawn by sedimentary facies modeling, and porosity model and permeability model were established under the constraint of sedimentary facies. At last, by analyzing sand body connectivity and reservoir property limit, it is considered that the reservoir properties of the sand group 1 of Chunxia sub-member are better than others. Sand bodies near Gao 89, Fan 142 and Fan 5-3 wells are favorable transport systems and hydrocarbon accumulation areas.
