Description
Technical Field
The invention belongs to the technical field of petroleum and natural gas exploitation, and relates to a system for experimentally simulating carbon dioxide displacement oil gas.
Background
Petroleum and natural gas are important strategic energy sources in China and have important significance in national economic development. In recent years, unconventional natural gas such as coal bed gas, shale gas and the like also develop rapidly in China, and the efficient exploitation and utilization of petroleum and natural gas can effectively relieve energy shortage. CO 2 is used as greenhouse gas, and large-scale emission can cause serious environmental damage, so that the temperature is increased, and the sea level is increased. The viscosity of petroleum can be effectively reduced, the natural gas can be replaced, and the oil and gas yield can be improved by replacing and displacing the petroleum and the natural gas with CO 2, and in addition, the carbon dioxide hydrate can be permanently sealed in an underground reservoir by replacing and displacing the petroleum and the natural gas, so that the method is a feasible method for reducing CO 2 emission. The advantages of carbon dioxide displacement and displacement of oil and gas are: carbon dioxide is injected into the stratum, so that the energy of the oil-gas layer can be improved, the viscosity of petroleum is reduced, and the flow of petroleum in the stratum is facilitated. The adsorption capacity of carbon dioxide to shale and coal rock is larger than that of methane, and when carbon dioxide is injected, CH 4 replacement efficiency can be effectively improved, and the yield of natural gas is improved. On one hand, with the increase of emission reduction pressure of greenhouse gases, carbon dioxide is injected into a stratum to displace and replace oil gas, so that the emission of carbon dioxide in the atmosphere can be reduced, the stability of an oil gas reservoir is maintained, and the environment-friendly value and the economic value are achieved.
At present, the development technology of carbon dioxide applied to oil and gas is still immature, the effect of improving the yield is controlled by different geological backgrounds of oil and gas reservoirs, and the difference of the survival states of different natural gases in stratum is large, such as the viscosity of petroleum and the survival state of the natural gases in stratum. Different formations may also have different configurations, such as fracture development, formation dip, etc. Regarding the carbon dioxide replacement and displacement efficiency and effect under different oil and gas stratum geological backgrounds, the replacement effect of carbon oxide replacement and displacement by different oil and gas saturation and natural gas storage states is not quantitatively evaluated yet, and related simulation experiment equipment is lacked.
Therefore, it is necessary to form an apparatus and system that experimentally simulates carbon dioxide displacement of hydrocarbon.
