Description

technical field [0001] The invention relates to the technical field of oil and gas reservoir development, in particular to a dynamic and static rock mechanics parameter correction system. Background technique [0002] Oil and gas reservoir rock mass is a geological entity composed of a series of structural planes and structural bodies at a certain depth, at a certain temperature and pressure, and saturated with a certain amount of fluid by the porous medium material of the reservoir rock mass and its upper and lower surrounding rocks. Compared with near-surface engineering geology, it is generally buried deeper (the depth of the formation is generally several thousand meters), and it is under higher triaxial complex confining pressure (up to 200MPa), higher temperature (up to 200°C) and higher Under the conditions of high pore pressure (up to 200Mpa) and multiphase fluid saturation (oil, gas, water). This is very different from the environment of the rock mass in the shallo...

Problems solved by technology

[0003] For oil and gas reservoir rock mass with complex confining pressure, high temperature, high pore pressure, and multiphase fluids at depths of thousands of meters underground, the traditional static mechanical properties research is to drill cores under surface conditions and use triaxial stress A tester or an acoustic wave tester is used to conduct mechanical experiments on the cores taken out, such as taking the drilled cores to the ground laboratory at room temperature, normal pressure, and dry samples, or considering applying different confining pressures, or considering filling different saturated fluids for testing. Rock mechanics experiments, obviously, the rock mechanics parameters obtained by this prior art cannot fully represent the mechanical properties of oil and gas reservoirs under the conditions of underground high temperature, high pressure, high pore pressure, and multiphase saturated fluid, that is, it cannot guarantee Validity and accuracy of rock mass mechanical parameters in oil and gas reservoirs with complex confining pressure, high temperature, high pore pressure and multiphase fluids at depths of meters
