Temperature and pressure integrated testing device for migration law of controllable fracture MICP (Microbial Inductively Coupled Plasma) solution

The invention discloses a temperature and pressure integrated testing device for a migration law of a controllable fracture MICP solution. The temperature and pressure integrated testing device comprises a solution filling system, a temperature control system, a pressurization system, a test model box, a computer monitoring and control system and an image acquisition system. According to the invention, an indoor model test method is adopted to simulate a dynamic process that a microorganism mixed solution infiltrates along soil body cracks and diffuses towards soil bodies at two sides under the conditions of different crack opening degrees, temperatures and pressures; a concentration sensor is connected with a computer monitoring and control system, real-time monitoring is achieved, and the spatial distribution rule of the calcium ion concentration in the solution can be obtained. In the test, each parameter can be effectively controlled, the test data is more accurate, and the sample can be freely loaded and
