Description
Technical field
It is more particularly to a kind of to exploit day using stratum hydro-thermal degree and salinity the present invention relates to exploitation of gas hydrates field
The method and device of right gas hydrate.
Background technology
Gas hydrates as a kind of new energy of clean and effective, one of energy attracted most attention as 21 century.By
Largely it is present in seabed or permafrost region in gas hydrates, its storage capacity is huge, and the characteristics of with clean and effective, opens it
Hair prospect is very good.Therefore, as long as destroying it has equilibrium condition, so that it may so that it resolves into water and natural gas, so as to by its
It is mined.
For this feature, current natural gas exploiting method mainly has heat shock method, voltage drop method, chemical-agent technique to break day
The voltage stabilizing balance of right gas hydrate makes it decompose and displace CH4 using CO2.Existing production technique can't carry out business
Exploitation, but if technology maturation, large-scale business can be carried out and exploited, then gas hydrates will turn into 21 century
Instead of the new main energy sources of oil coal.
Gas hydrates be under the conditions of cryogenic high pressure, formation it is a kind of with cage structure like ice-like crystallised compound
Thing.Popular saying is exactly in fact that natural gas is held in the cage of hydrone formation, and Temperature-pressure Conditions change can just discharge natural
Gas.1 side's gas hydrates can discharge 164~180 cubes of methane gas and 0.87 cube of water in normal conditions.
Heat shock method is mainly by injecting hot water or steam, situ combustion method etc. to gas hydrates into heating,
So that formation temperature exceedes its equilibrium temperature, water and natural gas are resolved into, and then produce gas hydrates.But this method
Cause substantial amounts of thermal waste because heat transfer efficiency is not high, so as to considerably increase cost of winning.
Voltage drop method is mainly and promotes it to decompose by reducing gas hydrates stressor layer.Conventional method is by extracting
The free gas-bearing formation of gas hydrates layer bottom realizes reducing the pressure of gas hydrates, so as to change gas hydrates temperature
Press strip part, destroys its balance, makes gas hydrate dissociation.But this method requirement gas hydrates layer bottom has free
Gas-bearing formation, and because gas hydrate dissociation heat absorption release water outlet can form ice, prevent gas hydrates from further decomposing.
Therefore its universality is not so good, with larger limitation.
Chemical-agent technique is changed by gas hydrates layer injection chemical reagent (such as salt solution, methyl alcohol, ethanol)
The phase balance condition of gas hydrates, reduces its equilibrium temperature so as to promote it to decompose, and the cost of this method is too big, uncomfortable
In commercial mining.It is at present to combine three of the above method to carry out exploitation of gas hydrates more.
The present invention is mainly on the basis of heat shock method and chemical-agent technique (salinity) theory, using gas hydrates layer
Under certain depth stratum water salinity and temperature carry out exploitation of gas hydrates.
The content of the invention
The purpose of the present invention is directed to the deficiency of existing heat shock method and chemical-agent technique exploitation of gas hydrate, proposition
A kind of method and device of utilization stratum hot brine stimulation for natural gas hydrate dissociation, stratum hot salt brine is produced and gas water is injected
Compound layer, using its temperature and salinity be quick, the economic exploitation gas hydrates, and the production waste water reinjection that will be produced, be separate
Enter brine layer, its salt solution is in debt, maintain its strata pressure to supplement, and helps to reduce surface production cost for wastewater treatment, subtracts
Few environmental pollution.

By stratum hot salt brine injection gas hydrates layer；A bite is made up of, sleeve pipe and note with adopting with note JingBJing sleeve pipe and water injection pipe
Water pipe annular space appropriate location is provided with packer, with exploitation of gas hydrate and to formation brine layer injection production waste water.Well
Mouth installation gas-liquid separator and ground face-pumping.
A kind of method and apparatus of utilization stratum hot brine stimulation for natural gas hydrate dissociation, its method is included stratum hot salt brine
Inject gas hydrates layer stage, exploitation of gas hydrate stage and produce the waste water stage to brine layer re-injection.Wherein open
Adopt the gas hydrates stage and to stratum re-injection production the waste water stage be in same well complete.Using existing stone
Oil, natural gas extraction drilling technology beat a series of wells in exploitation of gas hydrates area, constitute well pattern, are one with adjacent two mouthfuls of wells
Group, is now illustrated with one group of well to its method.
In the injection gas hydrates layer stage by stratum hot salt brine, in hot brine layer self-energy and re-injection waste water
Energy drive under, stratum hot salt brine by advance A, B well hot brine layer perforating and fracturing formed pressure-break or bored level
To A wells shaft bottom seepage flow, because A well annular spaces are provided with packer, hot salt brine will flow into the heat-insulated drinking-water pipe of A wells to well, and by water distribution
Device injection gas hydrates layer, it is using its salinity decrease gas hydrates equilibrium temperature and natural using the destruction of its temperature
Gas hydrate equilibrium condition, so that gas hydrate dissociation Cheng Shui and natural gas.
The exploitation of gas hydrate stage, the gas hydrates decomposed by stratum hot salt brine are with gas-liquid mixture
Form stratum in itself energy and injection stratum hot salt brine energy drive under, by advance A, B well gas hydrates layer
Pressure-break that perforating and fracturing is formed or institute's horizontal well drilling flow to well head to living together with adopting well B well seepage flow from B well annular spaces, enter
To ground gas-liquid separator, so as to isolate natural gas and waste water, natural gas divides by entering gas line network after further treatment
The waste water for separating out can re-injection enter brine layer, so as to recycle.
It is described to produce the waste water stage to stratum re-injection, through gas-liquid separator separates production waste water out, land used face-pumping to
Brine layer re-injection, because packer seals B well annular spaces, in the presence of pump pressure, waste water in A, B well hot brine layer by penetrating in advance
Pore pressure splits the pressure-break to be formed or institute's horizontal well drilling is injected into brine layer, and to supplement, its salt solution is in debt, maintain its strata pressure, and
Help to reduce surface production cost for wastewater treatment, reduce environmental pollution.
The present invention due to using such scheme, with following advantage：(1) temperature and salinity of stratum water are made full use of
Carry out exploitation of gas hydrate, rather than injection steam, hot water or chemical reagent, greatly reduce cost of investment；(2) due to
The production waste water of extraction is recycled, brine layer there will be sufficient energy, and can cut down surface production cost for wastewater treatment；
(3) production waste water reinjection is entered into brine layer, the volume in debt of brine layer can either be supplemented, stratum hot salt brine can be driven to enter again
Gas hydrates layer, remains that the production system has sufficient circulating energy；(4) sequence of operations of the present invention can be adopted
Completed with existing oil and gas drilling and production technology, required technical equipment is ripe.
