Embodiment Construction
[0034] The present invention provides a coal seam high-pressure water injection fracturing-seepage numerical simulation method based on the least pressure relief path algorithm. In order to make the purpose, technical scheme and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0035] The present invention provides a coal seam high-pressure water injection fracturing-seepage numerical simulation method based on the least pressure relief path algorithm. The coal body geometric model is established according to the water injection coal seam height, strike length and dip length, and on this basis, according to the water injection hole diameter , length, inclination and sealing length parameters to add the water injection hole model, add the fracture model accord...
