Description
Technical field
The present invention relates to a kind of anti-pit shaft combustion extinguishment tail pipe of combustion in situ and its application, when vigorous combustion occurs for pit shaft
When, releasable a large amount of fire-retardant gas control the intensity of a fire, protect test equipment and casing, belong to oilfield safety development field.
Background technology
Situ combustion technology is also known as fireflood, is a kind of production technique that can increase substantially recovery factor of heavy oil reservoir, mainly
It is by the use of the heavy component in in-place oil as fuel, by the use of air or oxygen rich gas as combustion adjuvant, takes spontaneous combustion and people
The methods of work is lighted a fire makes reservoir temperature reach crude oil burning point, and be continuously injected into combustion adjuvant, makes Crude Oil sustained combustion, and burning is anti-
A large amount of heat, heated oil reservoir should be generated so that reservoir temperature rises to 600~700 DEG C, and heavy component cracks at high temperature, note
Gas, the light oil of heavy oil pyrolysis generation, the gas of burning generation and the water vapour entered is used to drive crude oil to production well stream
It is dynamic, and produced from producing well.
Combustion in situ key technology research is concentrated mainly at present:Ignition method, completion method, tracing method, monitoring side
Method, output gas disposal, auxiliary exploitation, profile control closure, indoor simulation etc..Safety in production prediction scheme is also extended through in each of production
Link, but the uncertain security risk for always having some non-artificial influences the normal implementation of the technology, as offset well steams before lighting a fire
Channeling conductance causes this well temperature to increase oxidizing fire, and oil reservoir, which returns oil, leads to well cylinder roasting etc..Do not have once temperature in wellbore is excessively high
Timely processing is obtained, the lighter may damage test equipment, and severe one may burn out casing and cementing concrete, scrap producing well.
In the prior art, generally up to 800 DEG C, safe heatproof is usually no more than the instantaneous heatproof of combustion in situ high temperature resistance instrument
600 DEG C, to reach the purpose of protection test equipment and oil well, bottom hole temperature (BHT) must be controlled below 600 DEG C.Some wells are gone back in early period
Steam preheating stratum is needed, down-hole ambient temperature is sometimes up to 300 DEG C.Because the complicated factors such as underground high temperature, high pressure influence, ground
Available general fire extinguishing theory, equipment and medicament composition do not adapt to its demand.The Fire extinguishing club outside tubing string is generally arranged at by ruler
Very little limitation, Load is generally less, can only play the role of early warning or first arrival first attack, smaller when fire is greater.Water filling,
The note fire extinguishing such as nitrogen or carbon dioxide injection process needs the regular hour to prepare.
Through looking into, the relevant report of the anti-pit shaft combustion extinguishment technology of simple and effective combustion in situ is not found.

Interior filling ABC powder extinguishing agent, the interior filling magnesium carbonate solid of the second oil pipe;Upper sealing material selects the metal material of 660 DEG C of fusing point
Material, medium-tight material select the metal material of 600 DEG C of fusing point.
Specific embodiment according to the present invention, it is described fire extinguishing tail pipe total length can be determined according to oil well pocket length, one
As 10-80 meters.Upper and lower oil pipe (the first oil pipe and the second oil pipe) can be isometric, can not also be isometric.
Specific embodiment according to the present invention, the ABC powder extinguishing agent may include sodium bicarbonate powder, modified sodium salt
One kind in dry powder, sylvite dry powder, ammonium dihydrogen phosphate dry powder, diammonium hydrogen phosphate dry powder, phosphoric acid dry powder and Amino group powder extinguishing chemical
It is or a variety of.Loadings are usually every 0.03 cubic metre of rice bran oil pipe.
Specific embodiment according to the present invention, the second oil pipe is interior to load magnesium carbonate solid, and loadings are per rice bran oil pipe 0.03
Cubic meter.
Specific embodiment according to the present invention, the upper sealing material can for example select metallic aluminium (660 DEG C of fusing point).
Specific embodiment according to the present invention, the medium-tight material can for example select alloy aluminum (fusing point 600
℃)。
The contact surface of specific embodiment according to the present invention, sealing material and oil pipe can brushing organosilicon heat-resistant lacquer or
Other high temperature resistant dopes prevent electrochemical reaction from causing to seal premature failure.
The fire extinguishing tail pipe of the present invention, when use, are mounted in screen casing bottom, are arranged on shaft bottom.When bottom hole temperature (BHT) reaches 540
DEG C when, magnesium carbonate solid decomposes to give off carbon dioxide, to oil pipe internal pressurization;When bottom hole temperature (BHT) reaches 600 DEG C, intermediate seal
Fusing is unlocked, to entire oil pipe internal pressurization;When bottom hole temperature (BHT) reaches 660 DEG C, upper sealing fusing is unlocked, dioxy inside oil pipe
Change carbon ribbon pressure and spray into upper screen, and pour pit shaft, the control of fire is carried out to pit shaft.
So as to the present invention also provides a kind of fire extinguishing tail pipe by the present invention for the side of the anti-pit shaft burning of combustion in situ
Method, this method include fire extinguishing tail pipe of the present invention being mounted on screen casing bottom, are arranged on shaft bottom.
The technology of the present invention is suitable for well wellbore Normal Environmental Temperature at 400 DEG C hereinafter, working as burning oil well temperature up to 600
DEG C or more when (oil well firing temperature is generally lower than 550 DEG C, and fire extinguishing tail pipe is unlikely to destroy under normal circumstances, repeats profit
With), fire extinguishing Stern tube seal fusing, built-in chemical agent releases great amount of carbon dioxide foam, is water filling, note nitrogen or note titanium dioxide
The pressures such as carbon fire extinguishing process is raced against time, and is protected test equipment and casing, is guaranteed safe production.
