Abstract

The invention provides a rock fracture testing device and a rock fracture testing method. The rock fracture testing device is used for testing a to-be-tested rock, the to-be-tested rock is provided with a preset hole, and the rock fracture testing device comprises: a frame with a space for accommodating the to-be-tested rock; a first force application device, wherein the first force application device is installed in the frame, the first force application device is located in the preset hole under the condition that the to-be-tested rock is placed in the frame, the first force application device comprises a first force application piece, the first force application piece is matched with the hole wall of the preset hole, the to-be-tested rock is provided with a preset crack communicated with the preset hole, the preset hole is rectangular, and the first force application piece abuts against the hole wall, parallel to the length direction of the preset crack, of the preset hole. According to the technical scheme, the problem that the gravel winding and penetrating behaviors of the crack in the conglomerate cannot be visually observed in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the field of petroleum engineering rock mechanics, in particular to a rock fracture testing device and a rock fracture testing method. Background technique [0002] Today, with the increasing demand for energy, the demand for oil extraction is also increasing. Conglomerate reservoir, as one of the key points of oil and gas reservoir development, has important research and development significance. Conglomerate reservoirs are mainly exploited by hydraulic fracturing. As an important means of recovery, hydraulic fracturing has achieved good application results in the exploitation of conglomerate reservoirs. In the process of hydraulic fracturing, the shape and behavior of fractures greatly affect the fracturing effect and oil and gas production. [0003] In related technologies, the three-point bending fracture test is usually used to test the cracking process of conglomerate cracks. Since the three-point bending fracture test...
