Abstract

The invention discloses a numerical simulation method and device for oil-gas migration in a tight reservoir and relates to the technical field of petroleum. Hydrocarbon source rock grids are equivalent to formicaries, artificial ants representing oil gas are released from multiple hydrocarbon source rocks according to the hydrocarbon-generating intensity, paths of the artificial ants and the shut-down grids, namely the grids in an enrichment region set, are recorded, and paths of all the artificial ants and the enrichment region set are acquired. Compared with a Darcy seepage manner simulation method, the method is simpler and more convenient, the effect more approaches practical conditions, the prediction precision is high, and meanwhile, quick calculation is realized due to simplicity of the method.

Description

technical field

[0001] The invention relates to the field of petroleum technology, in particular to a numerical simulation method and device for oil and gas migration in tight reservoirs. Background technique

[0002] As an effective replacement resource, tight oil has been successfully explored and developed around the world. This is another important breakthrough in the oil field since the tight sandstone gas reservoirs in the 1980s.

[0003] The migration and accumulation of oil and gas is the key content of oil and gas exploration, which profoundly affects the methods and ideas of oil and gas exploration. As a dynamic process that occurred in geological history, it is impossible to directly observe oil and gas migration in tight reservoirs; due to the limitation of experimental technical conditions, large-scale, long-term experiments that can consider the influence of various factors are often impossible to realize. Therefore, mathematical simulation technology is beco...
