Description
Technical Field
The invention relates to the field of natural gas hydrate dynamic monitoring experiment devices, in particular to a hydrate reservoir interwell electrical dynamic monitoring simulation experiment device.
Background
Natural gas hydrate (NaturalGasHyrate/GasHyrate), organic compound, formula CH4·nH2And O. Namely, the combustible ice is an ice-like crystalline substance which is distributed in deep sea sediments or permafrost in land areas and is formed by natural gas and water under high pressure and low temperature conditions. They are also called "combustible ice" (combublice) or "solid gas" and "vapor ice" because they look like ice and burn on fire. In essence, a solid mass. A1 cubic meter "combustible ice" may contain 164 cubic meters of methane gas and 0.8 cubic meters of water. The 'combustible ice' is a byproduct of natural gas, has approximately the same application range as the natural gas, and is a typical petroleum substitute. The combustible ice is extremely easy to burn, and under the same condition, the energy generated by burning the combustible ice is dozens of times higher than that of coal, petroleum and natural gas, so that the combustible ice is known as super energy in the future. The natural gas hydrate has high resource density, wide global distribution and extremely high resource value, thereby becoming a long-term research hotspot in the oil and gas industry.
At present, the natural gas hydrate exploitation technology is still in a research stage, a set of forming standards are not made in the development of natural gas hydrates in various countries in the world, an indoor experimental research method is still the main body of the natural gas hydrate exploitation technology research, and common methods for detecting the natural gas hydrates include an optical method, an acoustic method, an electrical method and the like. For example, the generation and decomposition of natural gas hydrate in pure water can be judged according to the change of the light transmittance, the light transmittance is suddenly reduced when the temperature is reduced under a certain pressure and a large amount of hydrate is generated, and then the temperature is slowly increased, and the light transmittance is suddenly increased when the hydrate is decomposed. However, in order to simulate the marine natural gas hydrate, a mixture of water, sand, natural gas and the like is needed, and the effect of the light transmittance detection method is not obvious because the mixture is not transparent. Other monitoring methods, such as an ultrasonic monitoring method, a Time Domain Reflectometry (TDR) technology, an imaging (CT) technology and the like, can also visually, accurately and quantitatively observe and calculate the generation and decomposition of the natural gas hydrate.
However, no simulation experiment equipment for monitoring hydrate resistivity imaging around and between wells is reported in the process of forming and exploiting the simulated sea natural gas hydrate in the reservoir at present.
