A rotating device for a natural gas hydrate development simulation experiment device

Abstract

The invention discloses the rotating device of a natural gas hydrate development simulation experiment device. The device comprises a model support pedestal and a model body. The model support pedestal is provided with a rotation mechanism used for driving the model body to rotate. The model body is provided with a locking mechanism used for maintaining inclined state stability. The upper end surface of the model body is provided with a model well pattern. The rotation mechanism comprises a servo motor and a driving gear. One side of the model support pedestal is provided with two support stand columns. A straight row fixing rod is arranged between the two support stand columns. The straight row fixing rod is provided with a large diameter arc plate. The large diameter arc plate is rotatedthrough the intermeshing of a toothed-shaped strip and the driving gear. The outer side surface of the large diameter arc plate is provided with pushing long rods. The end portions of the two pushinglong rods are installed on the center positions of the front and rear plates of the model body. Through comparing the mining dynamic characteristics of hydrates under different well pattern modes andwell pattern density conditions, a well pattern development plan can be optimized, which greatly expands a research scope.

Description

technical field [0001] The invention relates to the technical field of hydrate simulation devices, in particular to a rotating device of a natural gas hydrate development simulation experiment device. Background technique [0002] Considerable reserves promote the continuous progress of development technology, and technological innovation will drive the efficient development of reserves. Since this century, the whole world has recognized that natural gas hydrate is a clean energy alternative to conventional fossil fuels. More than 200 hydrate deposits have been discovered in the world. Based on the current energy consumption trend, only 15% of hydrate mining can be used globally for 200 years. However, the stable temperature and pressure conditions formed by itself determine the particularity of its mining method. In addition, the impact of its mining process on the environment needs further evaluation. Therefore, most of the current research on hydrate mining is still in ...

Problems solved by technology

[0008] (1) Existing simulation devices cannot construct specific stratum structures based on actual geological data, or simulate the actual environment through stratum structures. Because this process is difficult to simulate effectively, the simulation effect is different from the actual results. Inconsistencies or obvious differences lead to simulation results that cannot be directly used to guide actual production, but can only be used as an auxiliary basis for theoretical guidance;

[0009] (2) Existing simulation devices are often closed, and the simulated conditions are limited to the model body, and all its parameters and simulation conditions cannot be combined to form a dynamic equilibrium, which cannot simulate hydrate The dynamic environment, especially in the process of mining, the environment in which it is located is in the process of establishing balance and destroying balance, so it is impossible to simulate the dynamic mining process;

[0010] (3) In the existing simulation device, there is a fixed structure between the model body and the base, but this fixed structure limits the scope of application of the model, that is, for a model, what is preset to simulate Well patterns of different types can only simulate this type and cannot exceed this range, which is obviously unscientific
