On the basis of the reservoir controlling mode of ＂facies-fluid potential integration＂, combined with the theory of ＂source rock control＂, the quantitative model of reservoir control by ＂ source rock-facies-fluid potential integration＂ is presented; at the same time, with the help of the model, the hydrocarbon accumulation process is researched for the cross section from Well Jin 8 to Well Bin 188 on the south slope of Dongying Sag. The results show that according to the index distribution of the above integration in the period of hydrocarbon accumulation, three hierarchies of favorable blocks are determined across the above section ; the most favorable block is labeled as Hierarchy I area, which has the super accumulation conditions from the very beginning to nowadays; the moderate favorable block is shown as Hierarchy II area, which has advantageous accumulation conditions in the most period; the rest block having the advantageous conditions in a certain time is regarded as Hierarchy llI area. There are the highest integration index in the beach-bar sand on the gentle slope belt of the above section, so this region is con- sidered as the most favorable （ Hierarchy I ） areas ; the turbidite lenses at the bottom of the slope, the uplifted- wall structural trap of the synsedimentary faults and the delta of the gentle slope belt show the moderate favorable facies and fluid potential, so they are regarded as relatively favorable areas （ Hierarchy II ） ; the beach-bar sand at the bottom of the gentle slope can be enriched by hydrocarbon with the help of the overpressure on the hydrocarbon and finally accumulate the reservoirs--Hierarchy III favorable block.
