Description

Technical Field

[0001] The invention relates to the technical field of in-situ mining of oil shale, and in particular to an oil shale pyrolysis reaction experimental device. Background Art

[0002] Energy is the material basis of human social activities and the cornerstone of a country's economic development. Only with sufficient and high-quality energy can the country's health and prosperity, social stability and development, and the improvement of personal living standards be achieved one by one. The energy issue is a very important global and strategic issue related to the country's economic and social development and the level of people's living standards. Traditional fossil energy includes coal, oil and natural gas. With the increase of human industrial activities, their reserves are constantly decreasing, and new energy cannot make up for their loss in a short time. Therefore, finding alternatives to traditional fossil energy is a key task in the current development of science and technology.

[0003] Oil shale is an unconventional oil and gas resource. It is listed as a very important replacement energy source in the 21st century due to its rich resources and feasibility of development and utilization. Oil shale is also called kerogen shale. It is mainly composed of a large number of inorganic minerals and solid organic matter contained in its skeleton. Among them, the inorganic minerals are mainly clay minerals such as kaolinite and illite, supplemented by some sulfides and carbonate minerals, etc. The organic matter is mainly composed of kerogen, i.e. "kerogen", and a small amount of asphaltene, etc., which are generally insoluble in organic solvents such as petroleum. The industrial grade and development and utilization value of oil shale in different regions are usually measured by the oil content. The reserves of oil shale in my country are about 720 billion tons. According to the average oil content of 6% to 7%, the shale oil reserves can reach 47.6 billion tons.

[0004] At present, there are many methods for in-situ mining of oil shale. According to the heating method, it can be divided into conduction heating, convection heating and radiation heating. The main feature of conduction heating is that the heating method is flexible and easy to control, but the heating speed is slow and the energy utilization rate is low; the main feature of convection heating is that the heating speed is fast and the dry distillation gas can be fully utilized. The technology is relatively mature, but the gas produced by open fluid heating and formation material exchange needs to be separated; the main feature of radiation heating is that the heating area can be selected, the heating is uniform, and the energy utilization rate is high, but the technology is in the research and development stage and is not mature enough.

[0005] The in-situ oil shale mining technology is to heat and pyrolyze the oil shale in-situ underground, thermally crack the kerogen in it into liquid and gaseous hydrocarbons, and then develop it using oil and natural gas mining technology. This process is affected by factors such as the oil content of the oil shale, mining temperature, pressure and catalyst. At present, there is a lack of equipment that can perform in-situ pyrolysis of large-scale oil shale.

[0006] The existing in-situ oil shale mining technology has the following disadvantages:

[0007] 1. It is impossible to accurately simulate the stress conditions around oil shale during in-situ mining.

[0008] 2. The confining pressure was not stable enough during the actual simulation experiment.

[0009] 3. True triaxial stress loading cannot be achieved.
