Abstract
Provided are a multi-scale and multi-parameter collaborative testing device and method for true triaxial hydraulic fracturing. The method includes: processing a retrieved rock sample, forming a fracturing port on the top surface of a rock specimen, placing a fracturing pipe in a hole, and connecting the fracturing pipe to a high-pressure water supply pipe; installing and connecting sensors on pressure plates, connecting wires, and turning on testing devices; sealing an airtight chamber, filling oil into the airtight chamber until the airtight chamber is full of oil, and keeping a room temperature constant; turning on a water supply device, starting hydraulic fracturing, and turning on testing modules at the same time; and stopping hydraulic fracturing after complete fracture of the specimen, returning oil to an oil tank, opening the airtight chamber to take out the specimen for observation and photographing, and performing data processing and analysis at the same time.
