The invention discloses an unconventional gas extraction visual simulator and an extraction simulation method of the unconventional gas extraction visual simulator. The simulator comprises a pumping unit dynamic simulation device, a vertical well simulation visual device and a temperature and pressure control system. The pumping unit dynamic simulation device is connected with the vertical well simulation visual device, the vertical well simulation visual device is arranged on a visual core holding unit model, and the visual core holding unit is submerged in water of a visual water tank. The temperature and pressure measurement and control system is used for measuring and adjusting temperature and pressure. The pumping unit dynamic simulation device, the vertical well simulation visual device and the temperature and pressure measurement and control system are all connected with the visual core holding unit model through interfaces. The simulator can vividly and visually study the water absorption and water permeability situation of roof and base plates in the vertical well extraction process of unconventional gas, the multi-item seepage problems and the situation that stratum rock debris is carried and migrated in a vertical well in the vertical well extraction process are studied, and basic parameters are provided for unconventional gas extraction.
Description
technical field [0001] The invention relates to the field of natural gas exploitation, in particular to a visual simulation device for unconventional natural gas exploitation and a method for simulating exploitation thereof. Background technique [0002] Unconventional natural gas is a kind of natural gas that is not controlled by structure and has accumulated in a large area. Today, the United States is the country with the most advanced natural gas exploration and development and production application technology in the world. The total annual output of three types of unconventional natural gas, such as tight gas, coalbed methane and shale gas, exceeds one-third of the total annual natural gas output. . On the plane, a wide range of natural gas exploration, development and production has been formed in the basin center, edge slopes and peripheral outcrops. On the profile, a large amount of natural gas was produced in shallow layers, exploration main depths and horizons, ...
