Abstract
The invention provides a method for jointly exploiting hydrates and hermetically storing carbon dioxide by the aid of quicklime and carbon dioxide injection processes. The method includes selecting hydrate occurrence regions as target regions and drilling quicklime and carbon dioxide injection wells and gas production wells; injecting quicklime into hydrate layers from the quicklime and carbon dioxide injection wells to form quicklime filling regions; completely carrying out reaction on the quicklime and water in the hydrate layers and then injecting the carbon dioxide from the quicklime and carbon dioxide injection wells; controlling outlet pressures of the gas production wells to allow gas production pressures to be higher than carbon dioxide and hydrate phase-balance pressures corresponding to the temperatures of the hydrate layers and lower than methane and hydrate phase-balance pressures corresponding to the temperatures of the hydrate layers; collecting methane gas at well mouths of the gas production wells. The method has the advantages that the hydrates can be safely and efficiently exploited, environmental problems such as decrease of the strength of existing hydrate layers and instability of strata in natural gas hydrate exploitation procedures can be effectively solved, and the purposes of hermetically storing the carbon dioxide and abating greenhouse effects can be achieved.

Belong to new forms of energy with field of new.
Background technology
With the development of social economy, total energy consumption is continuously increased, and traditional energy is day by day reduced, and various countries are provided to the energy
The contention in source is increasingly fierce, and various countries progressively start to pay attention to the development and utilization of new forms of energy.Wherein, gas hydrates have huge
Resource potential.In recent years, much the country of more early researching natural gas hydrate has been further spread out to its production technique, exploitation
Environmental problem for facing etc. is studied.Traditional gas hydrate mining methods have heat injection method, voltage drop method and note chemical reagent
Method, but all defects, heat injection method energy consumption is big, efficiency of utilization is low, voltage drop method gas hydrates property is had special will
Ask, note chemical-agent technique can bring some environmental problems etc..Three kinds of methods are all based on decomposing the principle of hydrate, can cause water
Compound layer intensity decreases, cause the environmental problems such as stratum unstability further.
Simultaneously as a large amount of uses of Fossil fuel, cause huge carbon emission, the greenhouse effect of the earth is caused,
Cause Global Temperature to raise, a series of adverse effects are generated to mankind's activity and ball ecological environment.Therefore, carbon dioxide envelope
It is considered as the effective way for mitigating greenhouse effect 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 product process for producing is a great problem, geology
The method of sealing up for safekeeping has carbon dioxide leakage problem, does not tackle the problem at its root.
Content of the invention
For the deficiency of prior art, the 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, with solving in hydrate recovery process
Layer destabilization problems and the too high problem of aquifer yield, and sequestration of carbon dioxide mitigates greenhouse effect.
Technical scheme：
The hydrate exploitation of a kind of note quick lime and carbon dioxide process and carbon dioxide sequestration integrated processes, step is as follows：
(1) it is target target area to choose sea bottom hydrate preservation region using high-resolution multichannel seismic exploration method, carries out
Quick lime and carbon dioxide injection well and gas-producing well drilling well, the bottom of quick lime and carbon dioxide injection well and gas-producing well is all non-
Between infiltration top lithosphere and impermeable bottom lithosphere, quick lime and carbon dioxide injection bottom are filled for quick lime
Area；
(2) to quick lime filling area, quick lime is injected from quick lime and carbon dioxide injection well；
(3) stop injection quick lime, after the water in quick lime and hydrate layer reacts completely, to quick lime and carbon dioxide
Injecting carbon dioxide in injection well, the injection pressure of carbon dioxide is 4-8MPa；
(4) control gas-producing well outlet pressure is 4-6MPa, to make aerogenesis pressure more than the corresponding titanium dioxide of hydrate layer temperature
Kohlenhydrate vapor pressure, less than the corresponding methane hydrate vapor pressure of hydrate layer temperature；
(5) gas-water separation being carried out in gas-producing well well head using whirlwind separator, collects methane gas using liquefaction storage tank,
And storage tank transport will be liquefied to 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 is close to carbon dioxide injection pressure, stop out
Adopt work.
Beneficial effects of the present invention：
1st, the present invention is initially with the mode of injection quick lime so as to water exothermic heat of reaction, improve hydrate layer temperature,
Methane hydrate is broken to balance each other, has been that methane hydrate decomposes offer heat, it is achieved that the exploitation of methane hydrate.
2nd, the water reaction generation calcium hydroxide that the water reaction that quick lime and methane hydrate decomposition are produced is generated, reduces water
Aquatic product in compound recovery process goes out, and enhances the stability of hydrate reservoir；The carbon dioxide of injection and calcium hydroxide reaction
Calcium Carbonate is generated, the purpose of carbon dioxide sequestration has been reached, while can also improve hydrate reservoir stability.
3rd, remaining carbon dioxide can migrate flowing in hydrate layer, as aerogenesis Stress control is being more than hydrate layer
The corresponding carbon dioxide hydrate vapor pressure of temperature, balances each other pressure less than the corresponding methane hydrate of hydrate layer temperature
Power, therefore carbon dioxide can by metathesis generate carbon dioxide hydrate, cause the methane output in methane hydrate,
Reach sequestration of carbon dioxide, methane hydrate exploitation and improve the purpose of reservoir stability.
Present invention achieves the safety and high efficiency of hydrate, effectively solves water during exploitation of gas hydrates
The environmental problems such as compound layer intensity decreases, stratum unstability, have reached sequestration of carbon dioxide, mitigate the purpose of greenhouse effect.
