Abstract

The invention relates to a detection method and a detection system for rock sample three-direction permeability. The detection method comprises that: a rock sample requiring detection is labeled according to axial directions of a three-dimensional rectangular coordinate system, and then is sequentially placed in a detection system along the labeling directions, sealing pressurization is performed, and then the permeabilities along different labeling directions are sequentially measured. The detection system comprises a clamping unit, a gas injection unit, a detection unit and a control unit, wherein the gas injection unit is connected with the clamping unit, the detection unit is arranged outside the clamping unit, the control unit is connected with the detection unit, the clamping unit comprises a clamper 12, a confining pressure sleeve 1, a transition sleeve 4 and a rock sample requiring detection 3 sequentially form a sleeved connection in the clamper 12, and one end of the rock sample requiring detection is connected with the gas injection unit. According to the present invention, drilling of the core column on the core is not required, and the cutting grinding manner is adopted to sample so as to improve the sampling success rate. In addition, with the detection method and the detection system, the three-direction permeability test can be performed on the one rock sample so as to improve the utilization rate of the rock sample and enhance the comparability of the test result.

Description

technical field [0001] The invention relates to the field of physical parameter measurement of rocks, in particular to a method for detecting three-dimensional permeability of rock samples and a detection system thereof. Background technique [0002] In the field of oil and gas geological exploration and development, permeability is an important parameter. In the laboratory, a standard core column is usually drilled on the rock sample, and the permeability of the core column is measured with a permeability tester to provide a basis for oil and gas exploration and development. Due to the anisotropic characteristics of formation permeability, this characteristic is of special significance for the exploration and development of oil and gas fields; therefore, when drilling a core column, it is necessary to drill an axial core column and a radial core column on the core, And mark the direction test respectively, and finally get the vertical permeability and horizontal permeabili...
