Abstract

According to the theory of facies-potential controlling on hydrocarbon accumulation in Dongying Sag, in combination with related research, the mechanismof facies-potential controlling on pool formation is analyzed. Based on previous studies, a quantitative research on facies and fluid potential recovery during the hydrocarbon accumulation period is carried out and the recovered palaeopressure in the inclusion is deemed as “residual pressure” which was formed after the filling process completed. In combination with the characteristics of staged filling process during the hydrocarbon accumulation period, interrelations of all kinds of energies are discussed. An analogical method is used to study the reservoir pore structure in the hydrocarbon accumulation period. Taking the linked well section among Li 92, Li 54, and Li 853 in Li 85 block as an example, the equation of oil saturation is formulated, the oil saturation of this section in each hydrocarbon accumulation phase is calculated, and it is concluded that the main filling process was in the third phase for Li-85 block.
