A device and method for preparing double-porosity transparent gas-bearing rock mass

Abstract

The present invention relates to a device and a preparation method for preparing a double-porosity transparent gas-bearing rock mass, wherein the device for preparing a double-porosity transparent gas-bearing rock mass includes a core preparation device, an inflatable device in the rock body, a gas delivery control system, a moving The control system, vacuum pumping device, temperature control system, gas delivery control system are connected to the inflatable device in the rock body through the gas transmission tube, the motion control system is connected to the sliding polished rod through the rotating screw, and the inflatable device in the rock body is placed in the rock mass forming mold. The vacuum pumping device is connected to the rock mass forming mold, and the temperature control system is connected to the water bath box; the core preparation device includes a grading raw material storage container, a mixing and stirring device, a conveying controller, a rock mass forming mold, and a water bath box. The rock mass forming mold is placed in a water bath In the box; the inflatable device in the rock body is composed of a sealed box, a gas distributor, a seam-making needle, and a sliding polished rod; the raw materials for preparing the visualized core are composed of epoxy resin and curing agent. The present invention selects epoxy resin and curing agent as raw materials, and the colored pore and fissure structure can be clearly reflected.

Description

technical field [0001] The present invention relates to a method and a preparation device for unconventional oil and gas reservoirs such as tight gas, shale gas, and coalbed methane, and related gas-bearing rock masses, and specifically relates to a device and preparation for preparing double-porosity transparent gas-bearing rock masses method. Background technique [0002] Rock mass fracturing is currently the most widely used technical method in the technical fields of conventional and unconventional gas reservoir exploitation and stimulation measures such as oil and natural gas, shale gas and coalbed methane. However, the description of fracture formation after fracturing is the "bottleneck" and core problem of unconventional oil and gas rock mass fracturing. At present, domestic and foreign studies on the expansion of rock mass fracturing fractures are all based on non-visualized opaque rock mass fracturing fracture research, and even some related experiments need to cu...
