Description
Technical Field
The utility model relates to the field of petroleum exploitation experiments, in particular to a visual thickened oil flue gas exploitation simulation device.
Background
The oil field is mainly based on the natural energy of the stratum in the early exploitation stage, but the energy of the oil deposit is gradually reduced along with the increase of the exploitation time, and the oil deposit must be supplemented by external energy to recover the energy of the oil deposit so as to ensure the continuous production of oil. At present, measures such as water injection or gas injection and the like are adopted in China, but most oil reservoir reservoirs in China belong to continental sedimentary layers, the reservoir heterogeneity is relatively serious, the viscosity of part of crude oil is relatively high, the water content is relatively high, part of oil fields enter the middle and later periods of exploitation, the recovery ratio is relatively low, the cost is relatively high, and a large part of crude oil is difficult to economically exploit.
The flue gas contains a large amount of nitrogen and carbon dioxide which can not be utilized, if the flue gas is effectively recycled, the method not only can make contribution to environmental protection, but also can be used for oil field exploitation to improve economic benefits. The proportion of nitrogen in the flue gas is 80-85 percent, and the proportion of carbon dioxide is 10-15 percent. Domestic and foreign researches show that the injection of nitrogen and carbon dioxide into an oil reservoir is one of effective ways for improving the recovery ratio of crude oil and the development effect. The nitrogen has stable chemical property, larger volume coefficient and compression coefficient than other gases, belongs to inert gases, is not combusted, nontoxic and noncorrosive, and has low solubility in water. So it can be used to carry out non-miscible flooding, composite flooding, miscible flooding, gravity flooding, water-gas alternate flooding and other oil displacement modes. Carbon dioxide has a high solubility in both water and oil, and when dissolved in large quantities in crude oil, causes the oil to swell in volume and the viscosity of the crude oil to decrease. Meanwhile, the carbon dioxide can also improve the fluidity ratio, extract light hydrocarbon, improve the permeability of the oil reservoir and the like.
In recent years, fog weather frequently occurs, and the degree of environmental management by people is gradually increased, so that the flue gas oil displacement technology has a new development space, and the flue gas oil displacement is more economic and cost-effective than nitrogen gas oil displacement in consideration of environmental benefits. At present, flue gas flooding is gradually applied to oil reservoir development, and researches show that flue gas is injected into an oil reservoir to promote the volume expansion of crude oil, so that the recovery ratio can be effectively improved.
The development experiment is the basis of oil and gas field development, not only can provide basic oil reservoir parameters for the work of reserve calculation, development scheme compilation, numerical reservoir simulation and the like of an oil and gas reservoir, but also can provide method guarantee for solving a plurality of problems encountered in oil reservoir development, the sand filling device is one of basic components with the most extensive application in the development experiment, but at present, aiming at flue gas oil displacement, the existing simulation experiment device has low precision, only can obtain conventional displacement data, and cannot visually and intuitively observe the change of oil displacement states at different positions in the experiment process, and aiming at the problems, the utility model provides a visual oil flue gas exploitation simulation device for thick oil.
