Abstract

The invention provides a method and a device for correcting dynamic and static rock mechanical parameters. The method includes: measuring rock mechanical parameters of a hydrocarbon reservoir; performing statistics on influencing parameters of rock mechanical properties of the hydrocarbon reservoir; acquiring correlations between the rock mechanical parameters of the hydrocarbon reservoir and the influencing parameters of the rock mechanical properties of the hydrocarbon reservoir; and recovering a hydrocarbon reservoir rock mechanical underground in-suit model, according to the rock mechanical parameters and the correlations between the rock mechanical parameters of the hydrocarbon reservoir and the influencing parameters of the rock mechanical properties of the hydrocarbon reservoir. The method and the device can increase the validity and the accuracy of the recovery of the hydrocarbon reservoir rock mechanical underground in-suit model.

Description

technical field [0001] The invention relates to the technical field of oil and gas reservoir development, in particular to a method for correcting dynamic and static rock mechanics parameters that vary with confining pressure, pore pressure, temperature, and fluid, and a method that varies with confining pressure, pore pressure, temperature, and fluid. Dynamic and static rock mechanics parameter correction device. 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)...
