针对地层的实际情况，考虑产层、盖层、底层的岩石力学参数，如泊松比、弹性模量、断裂韧性和地应力互不相同时，建立了包括三维裂缝延伸模型和酸液运移分布模型的酸压模拟三维模型，并编制了酸压设计软件。该软件全面考虑了温度场、同离子效应、反应活化能变化等影响，能模拟碳酸盐岩油气层各种应力分布和酸压裂缝延伸及酸液运移情况。 According to the actual situation of the strata, considering the rock mechanics parameters of the pay zone, caprock and basement, such as Poisson’s ratio, elastic modulus, fracture toughness and in-situ stress, the model including three-dimensional crack extension and acid migration Distribution model of acid pressure simulation three-dimensional model, and the preparation of the acid pressure design software. The software fully considers the influence of temperature field, the same ion effect and the reaction activation energy, and can simulate various stress distribution and acid fracturing extension and acid migration in carbonate reservoirs.
