文摘

With the aim to calculate more accurately 3-D fluid potential and predict the direction of petroleum migration and accumulation, a new method is presented based on Hubbert’s fluid potential model and a comprehensive 3-D pore pressure prediction method. An improved global pore pressure prediction algorithm is used in conjunction with an integrated 3-D pore pressure prediction method to reduce 3-D pore pressure uncertainties and improve 3-D fluid potential accuracy. Then, 3-D fluid potential is obtained according to the relationship between 3-D fluid potential and 3-D pore pressure through programming. The new 3-D fluid potential calculation method has high continuity and accuracy both vertically and horizontally which is helpful in analyzing the characteristic of formation fluid potential and predicting the oil and gas migration and accumulation. The application of the new method in Boxing Sag presents satisfactory result for prediction of petroleum migration direction and favorable oil accumulation.KeywordsPetroleum migrationFluid potential3-D pore pressureSubtle reservoir
