Summary: | The invention relates to the technical field of oil production engineering, in particular to an oil reservoir current crustal stress rapid calculation method, mainly solving the problem that the existing method cannot simply and quickly calculate the current crustal stress of the oil reservoir and determine the change rule of the crustal stress. The oil reservoir current crustal stress rapid calculation method includes the steps: according to initial X-mac logging information and density logging information of a construction well or other wells in a construction well block, carrying out statistics and calculation of initial crustal stress; testing initial and dynamic Young modulus, Poisson's ratio and Biot coefficient by using a triaxial rock mechanics test system, and fitting a relationalexpression of the Young modulus, Poisson's ratio, Biot coefficient and formation pressure; and finally, under the current stratum pressure condition, calculating the current Young modulus, the current Poisson's ratio, the cu |
