Abstract

The application discloses a method, device and storage medium for determining the accumulation coefficient of heterogeneous reservoirs, belonging to the field of oil and gas exploration and development. The method includes determining a median depth of a heterogeneous reservoir. According to the median depth of the heterogeneous reservoir, the lower limit of the accumulation porosity of each single lithology reservoir in the heterogeneous reservoir is determined. According to the lower limit of accumulation porosity of each single lithology reservoir in the heterogeneous reservoir, the lower limit of displacement pressure of each single lithology reservoir in the heterogeneity reservoir is determined. According to the lower limit of the displacement pressure of each single lithology reservoir in the heterogeneous reservoir, the lower limit of the displacement pressure of the heterogeneous reservoir is obtained. The accumulation coefficient of heterogeneous reservoirs is determined by the lower limit of displacement pressure of heterogeneous reservoirs. The application can determine the accumulation and accumulation coefficient of heterogeneous reservoirs, which improves the accuracy of the judgment results compared to judging the difficulty of accumulation and accumulation based on the lower limit of displacement pressure of a single lithology.

Description

technical field [0001] This application relates to the field of oil and gas exploration and development, in particular to a method, device and storage medium for determining the accumulation coefficient of heterogeneous reservoirs. Background technique [0002] Oil and natural gas are indispensable strategic resources for the survival and development of a country, and play an inestimable role in ensuring national economic and social development and national defense security. After oil and natural gas are generated from source rocks, they migrate into reservoirs and accumulate to form accumulations. Capillary force, viscous force and adsorption force of rocks can all become the resistance to oil and gas accumulation, and capillary force is the main body of resistance to accumulation, and the greater the capillary force, the more difficult it is for oil and gas to accumulate and form. Therefore, determining the capillary force is crucial to judging the possibility of oil and ...
