Problems solved by technology

[0008] Due to the different geological conditions and the composition of gas hydrates in various places, the formation mechanism is different, so the research is carried out through simulation experiments to directly guide the exploration and development, but the existing experimental equipment is relatively simple, and it is difficult to meet the current research needs of marine gas hydrates At the same time, there are still not many professional simulation laboratories that fully serve the exploration and development of marine gas hydrates

Abstract

The present invention discloses a natural gas hydrate one-dimensional production simulation experimental device. It is characterized by that its simulation experimental tube is placed in a temperature control box; the interior of said simulation experimental tube is a sealed simulation cavity. The front end of said simulation experimental tube is communicated with natural gas supply unit and working fluid supply unit by means of control valve, and its rear end is communicated with rear processing unit by means of control valve. In the interior of simulation experimental tube, natural gas supply unit, working fluid supply unit and rear processing unit an induction element is set respectively, and every induction element is electrically connected with data processing unit respectively.

Description

technical field [0001] The invention relates to an experimental device, in particular to a one-dimensional exploitation simulation experiment device of natural gas hydrate. Background technique [0002] Natural gas hydrate refers to a cage-like crystal substance formed by natural gas and water at a certain temperature and pressure. It can burn when exposed to fire, commonly known as "combustible ice". Early research on natural gas hydrate was mainly to solve oil and gas production. The blockage of pipelines and equipment during transportation and transportation is mainly to inhibit the formation of hydrates. With the continuous deepening of people's research on hydrates, the characteristics of hydrates and their impact on the environment have become more and more known to humans, and more importantly, their value as an effective alternative energy has also become increasingly prominent. [0003] Gas hydrates can exist in nature in many ways. Based on the characteristics of ...
