Abstract

The invention discloses a multifunctional rock sample testing device, which relates to the technical field of oil and gas field exploration and development, and is used to solve the technical problems that the existing equipment cannot simultaneously complete the testing of rock core porosity and permeability, including a rock core chamber, a vacuum machine, and a standard pressure chamber , the top of the core chamber is connected to the axial pressure pump and the backpressure pressure pump through the manifold, the middle of the core chamber is connected to the confining pressure pump through the manifold, the pipe manifold connecting the core chamber to the standard pressure chamber is connected to the pore pressure pump, the core chamber and Control valve 1 and pressure gauge 1 are set on the back pressure pressure pump connection manifold, control valve 2 and pressure gauge 2 are set on the core chamber and axial pressure pump connection manifold, and control valve 2 and pressure gauge 2 are set on the core chamber and confining pressure pump connection manifold. Valve 3 and pressure gauge 3, control valve 4 and pressure gauge 4 are set on the connecting manifold between the core chamber and the standard pressure chamber. The present invention simultaneously completes the core pore pressure on one device by simulating the formation axial pressure, confining pressure and formation temperature. Degree and permeability testing.

Description

technical field [0001] The invention relates to the technical field of exploration and development of oil and gas fields, in particular to a multifunctional rock sample testing device. Background technique [0002] In the process of oil and natural gas extraction, there are flow characteristics of underground fluids. The medium of fluid flow is reservoir rocks. The flow of reservoir fluids in formation rocks involves the testing of various physical characteristics of formation rock samples, among which Including porosity and permeability. Porosity determines the storage performance of rocks, and permeability indicates the ability of reservoir rocks to allow fluid (oil, gas, water) to pass through under a certain pressure difference. Accurate measurement of permeability is the geological basis for oil and gas resource evaluation and development plan design. Accurate calibration of permeability directly affects the production of oil and gas wells. [0003] The permeability o...
