Description

technical field [0001] The invention belongs to the field of geological oil and gas field engineering, and in particular relates to a three-dimensional simulation experiment device for natural driving energy of fracture-cavity oil and gas reservoirs. Background technique [0002] In the process of oil field development, the natural energy of oil and gas reservoirs is firstly used for development, so that the cost of oil and gas extraction can be reduced. Natural displacement energy can be roughly divided into five categories: water pressure drive, air pressure drive, elastic drive, dissolved gas drive and gravity drive. For fracture-vuggy reservoirs, hydraulic drive and elastic drive are mainly used. The main storage space of fractured-vuggy reservoirs is caves, fractures also have certain storage capacity and serve as the main flow channels, and the matrix basically has no storage and seepage capacity. The fractures and vugs in the reservoir are diverse in shape and rando...
