AI Technical Summary

Technical Problem

The existing method of adding source rocks can easily destroy the already laid strata or structures, and there is a lack of materials that can directly simulate source rocks within the model, resulting in poor simulation results.

Method used

A mixture of butter and quartz sand was used as the source rock simulation material. The mixture was prepared in different proportions according to the organic carbon content parameters of the source rock and directly laid in the experimental model to avoid the injection method from destroying the model structure. The simulation model was constructed in combination with the stratigraphic sequence and structural characteristics for heating simulation.

Benefits of technology

It achieves the real simulation of the structural evolution process without destroying the model structure, enriches the technical routes and increases the selection space, and improves the accuracy of oil and gas accumulation simulation.

Abstract

The present invention discloses a method for simulating oil and gas reservoir formation and exploration based on hydrocarbon source rock simulation materials. The method may include: obtaining organic carbon content parameters of hydrocarbon source rocks at different locations within a study area; based on the organic carbon content parameters, preparing and mixing hydrocarbon source rock simulation materials with butter and quartz sand to obtain mixtures of hydrocarbon source rock simulation materials at different locations; arranging the hydrocarbon source rock simulation material mixture at different locations in an initial experimental model based on the stratigraphic sequence and structural characteristics of the study area to construct a structural reservoir model containing the hydrocarbon source rock simulation material mixture; constructing a heating model based on the maturity time of hydrocarbon source rocks in the study area, and conducting reservoir formation simulation experiments on the structural reservoir model using the heating model. The hydrocarbon source rock simulation material is used to pave different locations in the initial experimental model, eliminating the need to inject hydrocarbon source rock powder by injection, which does not damage the structure of the initial model. Unexpected technical effects were achieved through simulation experiments.
