Abstract

The invention relates to a device for testing rock property parameter variation after microwave heating. According to the device, generated microwaves are adopted to heat a rock sample, and compared with the prior art, the device is capable of not only testing data of adsorption, transfusion and deformation of a rock sample in a common environment, but also testing data of adsorption, transfusionand deformation of the rock sample under a microwave in-situ heating condition, is capable of achieving experimental study on microwave heating influence upon rock samples in three-axis confining pressure environments, has the characteristics of multiple functions and multi-field coupling. A use method of the device provided by the invention is simple and convenient to operate.

Description

technical field [0001] The invention relates to an experimental device for heating rock mass by using microwave radiation, in particular to an experimental device for measuring the change of rock mass physical property parameters after heating. Background technique [0002] Unconventional natural gas extraction is a research hotspot in the current energy field, but due to the characteristics of the reservoir itself, the permeability is generally low, making extraction difficult. Conventional measures such as hydraulic fracturing achieve the purpose of reservoir permeability enhancement by destroying the rock mass structure of the reservoir and increasing the impact range of drilling, but the effect is not good. Microwave in-situ heating of reservoirs to promote unconventional natural gas extraction is currently a novel technical means, but it is still in the laboratory research stage, and there is a lack of relevant experimental equipment to assist the development of researc...
