Technical field
The present invention relates to it is a kind of note quick lime and carbon dioxide process hydrate exploitation and carbon dioxide sequestration integrated processes,
Belong to new energy and field of new materials.
Background technology
With the development of the social economy, total energy consumption is continuously increased, traditional energy is increasingly reduced, and various countries provide the energy
The contention in source is increasingly fierce, and various countries gradually start to pay attention to the development and utilization of new energy.Wherein, gas hydrates have huge
Resource potential.In recent years, much the country of more early researching natural gas hydrate has further spread out to its production technique, exploitation
The researchs such as the environmental problem faced.Traditional gas hydrate mining methods have heat injection method, voltage drop method and note chemical reagent
Method, but defect, heat injection method energy consumption is big, efficiency of utilization is low, and voltage drop method has special want to gas hydrates property
It asks, note chemical-agent technique can bring some environmental problems etc..Three kinds of methods are all based on the principle for decomposing hydrate, can cause water
Nitride layer strength reduction is closed, the environmental problems such as stratum unstability are further caused.
Simultaneously as a large amount of uses of fossil fuel, cause huge carbon emission, the greenhouse effects of the earth are caused,
Cause Global Temperature to increase, a series of adverse effects are produced to mankind's activity and ball ecological environment.Therefore, carbon dioxide seals
It is considered as the effective way for mitigating greenhouse effects to deposit.Existing carbon dioxide sequestration method is mainly with chemical reaction method and geology
Based on sealing up for safekeeping.But chemical reaction method can consume a large amount of chemical raw materials, and the reaction product processing generated is a great problem, geology
The method of sealing up for safekeeping has carbon dioxide leakage, does not tackle the problem at its root.
Invention content
For the deficiency of prior art, the present invention provides the hydrate exploitation of a kind of note quick lime and carbon dioxide process and
Carbon dioxide sequestration integrated processes, its object is to realize hydrate safety and high efficiency, solve hydrate recovery process in
Layer destabilization problems and the excessively high problem of water yield, and sequestration of carbon dioxide mitigates greenhouse effects.
Technical scheme of the present invention：
A kind of hydrate exploitation and the carbon dioxide sequestration integrated processes of note quick lime and carbon dioxide process, steps are as follows：
(1) it is target target area to utilize high-resolution multichannel seismic exploration method to choose sea bottom hydrate preservation region, is carried out
Quick lime and carbon dioxide injection well and gas-producing well drilling well, quick lime and the bottom of carbon dioxide injection well and gas-producing well are non-
It permeates between top lithosphere and impermeable lower part lithosphere, quick lime and carbon dioxide injection bottom are filled for quick lime
Area；
(2) from quick lime and carbon dioxide injection well quick lime is injected to quick lime filling area；
(3) stop injection quick lime, after quick lime reacts completely with the water in hydrate layer, to quick lime and carbon dioxide
Carbon dioxide is injected in injection well, the injection pressure of carbon dioxide is 4-8MPa；
(4) control gas-producing well outlet pressure is 4-6MPa, and aerogenesis pressure is made to be more than the corresponding titanium dioxide of hydrate layer temperature
Kohlenhydrate vapor pressure is less than the corresponding methane hydrate vapor pressure of hydrate layer temperature；
(5) gas-water separation is carried out using whirlwind separator in gas-producing well well head, methane gas is collected using liquefaction storage tank,
And liquefaction storage tank is transported into gas station using marine transport ship；
(6) quick lime of quick lime filling area is emptied using drilling equipment；
(7) repeat the above steps (2)~(6), until gas-producing well outlet pressure close to carbon dioxide injection pressure, stops out
Adopt work.
Beneficial effects of the present invention：
1, the present invention makes itself and water exothermic heat of reaction, improves hydrate layer temperature first by the way of injecting quick lime,
Methane hydrate is broken to balance each other, provides heat for methane hydrate decomposition, realize the exploitation of methane hydrate.
2, quick lime decomposes the water reaction generation calcium hydroxide that the water generated reacts generation with methane hydrate, reduces water
The aquatic products closed in object recovery process goes out, and enhances the stability of hydrate reservoir；The carbon dioxide and calcium hydroxide reaction of injection
Calcium carbonate is generated, has achieved the purpose that carbon dioxide sequestration, while hydrate reservoir stability also can be improved.
3, remaining carbon dioxide can migrate flowing in hydrate layer, since aerogenesis pressure is controlled more than hydrate layer
The corresponding carbon dioxide hydrate vapor pressure of temperature, methane hydrate corresponding less than hydrate layer temperature balance each other pressure
Power, therefore carbon dioxide can generate carbon dioxide hydrate by metathesis, lead to the methane output in methane hydrate,
Achieve the purpose that sequestration of carbon dioxide, methane hydrate exploitation and improves reservoir stability.
The present invention realizes the safety and high efficiency of hydrate, water during effective solution exploitation of gas hydrates
The environmental problems such as nitride layer strength reduction, stratum unstability are closed, has reached sequestration of carbon dioxide, has mitigated the purpose of greenhouse effects.
