Embodiment Construction

[0023] The present invention will be described in detail below in combination with specific embodiments.

[0024] The multifunctional natural gas hydrate synthesis reactor simulation experiment method of the present invention comprises the following six steps:

[0025] (1) Reactor cleaning: Use deionized water to clean the inner wall, top cover, and bottom of the reactor;

[0026] (2) Sediment preparation: According to the requirements of the hydrate samples required for the experiment, prepare a small reaction tank with suitable size and material, fill in the sediment samples of different types and water content required for the experiment, and place them in the multifunctional reaction tank after preparation middle;

[0027] (3) Pipeline connection and leak detection: connect the pipeline of the experimental device, open and close the corresponding valve, and inject a certain pressure of CH 4 And stand still to ensure that the experimental device has no leakage;

Abstract

The invention discloses a multifunctional natural gas hydrate synthetic reaction method and device. An aeration conduit of a CH4 gas bottle is provided with a supercharge pump; an opening part of the aeration conduit of the CH4 gas bottle is connected with a gas injection opening formed in a top cover of a reaction kettle; the reaction kettle is arranged in a constant-temperature air bathroom; a temperature probe and a pressure sensor on the reaction kettle are connected with an industrial control machine via a data acquisition unit. The multifunctional natural gas hydrate synthetic reaction method and device have the beneficial effects that hydrates of a plurality of different sediment systems can be synthesized at the same time, so that the experiment result is close to the practice; the preparation cycle of hydrate samples is shortened; the efficiency is enhanced; the accuracy and the reliability of the experiment result are increased.

Description

technical field [0001] The invention belongs to petroleum and natural gas, and relates to a multifunctional natural gas hydrate synthesis reaction method and device. Background technique [0002] Natural gas hydrate is an ice-like combustible solid substance formed by the interaction of natural gas and water under low temperature and high pressure conditions, also known as combustible ice, which is widely distributed in the world's submarine continental margins and permafrost regions. The main component of natural gas is methane (CH 4 >90%), also known as methane hydrate. At present, scientists from all over the world agree that the total carbon stored in natural gas hydrates worldwide is twice that of existing fossil fuels. As an energy resource, natural gas hydrate has broad application prospects and development space, so scientists from all over the world have carried out research on hydrate. [0003] At present, the research on natural gas hydrate mainly focuses on...
