Abstract

The invention discloses an integral shale matrix particle porosity and permeability measurement system and method. According to the invention, a constant-pressure and constant-volume pump is taken asan air source, so as to provide gas to the device, and volume change and readings of a pressure sensor and a differential pressure transducer of different stages such as during inflation, after inflation and during system stability are acquired, then the shale matrix particle porosity and permeability are measured according to the acquired various parameters. According to the invention, through one-step experimental operation, the shale matrix particle porosity and permeability can be measured, so that the experimental efficiency is improved.

Description

technical field [0001] The invention relates to the field of measuring porous and low-permeability shale parameters, in particular to an integrated measurement system and method for the porosity and permeability of shale matrix particles. Background technique [0002] my country is currently in a critical period of energy consumption transformation. Green and efficient natural gas resources will gradually replace traditional fossil fuels such as coal and oil, making clean energy a new driving force for my country's economic development; the development and exploitation of shale gas will become an important part of our country's and the world's. A new direction for the development of energy, but the pore structure in shale reservoirs is complex, with various shapes, and most of them are on the nanometer scale, and the porosity and permeability are very low. The conventional Darcy formula cannot be directly used to measure the permeability, and It is also difficult to measure it...
