NATURAL GAS HYDRATE MINERAL FRACTURING EXPERIMENT DEVICE

摘要

A natural gas hydrate mineral fracturing experiment device, comprising a support (1) and a reactor (2) disposed on the support (1) for synthesizing a sample and performing fracturing transformation on the sample. The reactor (2) is provided with a sample synthesis system (3), a permeability testing system (4), and a data acquisition and control system (6). A hydraulic fracturing system (5) used for performing the fracturing transformation is further disposed in the reactor (2). The device can synthesize natural gas hydrate sediments in situ under high-pressure and low-temperature conditions, perform fracturing experiments on the sediments, and measure the permeability thereof, thereby expanding the application range of existing experimental testing devices. In addition, the device can reasonably simulate reservoir ground stress and temperature and pressure conditions, can relatively completely restore conventional hydraulic fracturing operation steps such as liquid injection, fracturing, and propping agent addition, and can also measure changes in reservoir permeability before and after the fracturing and under different fracturing conditions and observe the fracturing effect.
