Abstract

The invention provides an axial compression loading device and a heat-fluid-solid coupling device, and relates to the technical field of oil gas scientific research. The axial compression loading device comprises a device body, wherein the device body comprises a housing; the device body also comprises at least two X-axis pressing rods, at least two Y-axis pressing rods and at least two Z-axis pressing rods arranged on the housing; the at least two X-axis pressing rods are arranged along X axis oppositely, the at least two Y-axis pressing rods are arranged along Y axis oppositely, and the at least two Z-axis pressing rods are arranged along Z axis oppositely; the center of the device body is provided with a loading mechanism. In the technical scheme, in order to realize the measurement ofthree-dimensional permeability, the pressing rods are arranged along the X axis, the Y axis and the Z axis in the three directions respectively, and the three-dimensional axial compression loading device is formed by using the relative pressing structures of the at least two pressing rods in each direction, so that independent loading of axial compression in the three directions can be realized, the situ conditions are simulated to the maximum extent, and the foundation is laid for the measurement of the permeability under suit conditions.

Description

technical field [0001] The invention relates to the technical field of oil and gas scientific research, in particular to an axial pressure loading device and a heat-fluid-solid coupling device. Background technique [0002] As the strong stress sensitivity and strong anisotropy of low-permeability, tight and other unconventional reservoirs are gradually recognized, how to simulate the three-dimensional deformation characteristics and seepage characteristics of rocks under real formation conditions has become a constraint on the development of tight oil and gas and even unconventional oil and gas resources. The bottleneck that urgently needs to be broken through in the development of core technologies. [0003] However, in the true triaxial fluid-solid and heat-fluid-solid coupling experimental device of the prior art, only the measurement of one-way permeability can be realized, and the measurement of three-dimensional permeability cannot be realized, and it cannot be used t...
