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 relatively few professional simulation laboratories that fully serve the exploration and development of marine gas hydrates

Abstract

The objective of the present invention is to provide a simulated experiment apparatus of comprehensive study various exploitation mechanism, exploitation dynamic, and proceeding optimizing and comprehensive evaluation to various exploitation methods. The apparatus includes three-dimensional model, natural gas supply unit, working solution supply unit, back pressure control unit, environment control unit and postprocessing unit. Applying the experimental apparatus can simulate vertical well cluster and horizontal well cluster simultaneity, utilizing visual window and optical fibre endoscope observing and simulating hydrated compound status inside the cavity, proceeding comprehensive evaluation to exploitation process and exploitation impression, being able to provide guide for gas hydrate exploitation.

Description

technical field [0001] The invention relates to an experimental device, in particular to a three-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 o...
