Abstract

The invention relates to a device for preparation of dual-porosity transparent gas bearing rock mass and a preparation method. Specifically, the device for preparation of the dual-porosity transparent gas bearing rock mass includes a core preparation apparatus, a rock mass inner inflation apparatus, a gas conveying control system, a motion control system, a vacuum air pumping apparatus, and a temperature control system. The gas conveying control system is connected to the rock mass inner inflation apparatus through a gas transportation pipe, the motion control system is connected to a sliding polished rod, the rock mass inner inflation apparatus is placed in a rock mass forming mould, the vacuum air pumping apparatus is in connection with the rock mass forming mould, and the temperature control system is connected to a water bath case. The core preparation apparatus consists of a graded raw material storage container, a mixing stirrer, a transportation controller, the rock mass forming mould, and the water bath case. The rock mass forming mould is disposed in the water bath case. The rock mass inner inflation apparatus consists of a sealed box, a gas distributor, fracture-making needles and the sliding polished rod. The raw materials for preparation of a visual core include epoxy resin and a curing agent. According to the invention, epoxy resin and the curing agent are selected as the raw materials, and the colored pore-fracture structure can be reflected clearly.

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...
