Description
Technical field
The utility model relates to a kind of high pressure mixed gas generating means that is used for the oil heating exploitation, belongs to the technical field of oil exploration equipment.
Background technology
The production practice of oil is broadly divided into primary oil recovery, secondary oil recovery and repeatedly recovers the oil.Steam-assisted recovery then is typical DP technology repeatedly.Steam-assisted recovery is to utilize the intensification effect of heat energy to reduce the viscosity of crude oil, also increases the pressure of oil reservoir simultaneously to a certain extent, thereby improves the oil recovery of oil well.
Since early 1980s, the practice of China's oil field utilization steam thermal recovery technology shows that this technology is applicable to the low exploitation periodic regime of 800m with oil reservoir in the overlying strata.In its recovery process, strata pressure constantly descends, after exploiting for 6~8 cycles, oil-well strata pressure has lost 70%~90%, promptly lost the necessary potential energy of thermal recovery, cause oil well low adopt can, especially a large amount of heavy oil wells enter the high all after dates of thermal recovery, are forced to closing well and stop adopting because of being lower than the thermal recovery economic boundaries.
Also there are many deficiencies in the steam heat excavating technology that with the high pressure steam boiler is technical characterictic.For example: smoke evacuation not only causes big heat loss, also causes environmental pollution; Equipment investment and operating cost height; Particularly the mobility extreme difference of complete equipment is difficult to adapt to the requirement of oil well working in dispersion.
The deficiency of high cycle of thermal recovery, deep fat, thickness oil reservoir being gathered at steam thermal recovery technology, a kind of new crude oil thermal recovery technology technology was proposed again in recent years---complex media (being the gaseous mixture of flue gas water vapour) thermal methods, be also referred to as gas-vapour thermal recovery, or abbreviate the gaseous mixture thermal recovery as.
Compare with above-mentioned steam boiler thermal recovery technology, Chinese patent application number is CN00210830.5, name is called " heavy crude heat extraction steam, combustion gas mixing gas injection device ", Chinese patent application and number is CN03278103.2, name is called " petroleum thermal recovery gaseous mixture gas injection device ", Chinese patent application and number is CN200420054883.6, and name is called " multifunctional high pressure burner with high efficiency " all certain improvement in succession in every respect.But still there is weak point in these Patent equipments aspect structural design, bring many difficulties to practical application.Be typically: burning indoor temperature too high (about 2000 ℃), under oil well back pressure conditions of higher (actual conditions are like this usually), cause flame high temperature center in the 1. combustion chamber to shift to the counter-fire face of head gradually, head is easily by scaling loss (as counter-fire end face, igniter igniter head, oil burner nozzle atomizer etc.); 2. the burning zone refractory lining is easy to generate explosion, degrades phenomenon under HTHP (2000 ℃, 16MPa), cause the result of use of refractory lining significantly to descend, thereby shortened the service life of burner (or gas injection device) (working day of a gas injection of less than sometimes) greatly.And so on, finally cause gas injection device reliability of operation and economy to be had a strong impact on.

Preferably, in the combustion chamber, inject a certain amount of water, can make the operating temperature in the combustion chamber stably drop to 1500 ℃-1600 ℃ from about 2000 ℃ from water injection hole.
Beneficial effect:
1,, greatly reduces operating temperature in the burning zone (dropping to after the water filling 1500~1600 ℃) by about 2000 ℃ of not water filling because injected water volume has absorbed a certain amount of combustion heat.The operating temperature of head and burning zone body and gaseous mixture generating means critical piece can both remain in the tolerance band of material, thereby improved the job stability of this device effectively, prolong the continuous firing cycle, made this device can become the approved product of effectively putting on market.
2, after the water filling, because the operating temperature in the combustion chamber can remain on 1500~1600 ℃, therefore, still can guarantee the temperature levels that burning zone is indoor, thereby guarantee the abundant burning of fuel, its efficiency of combustion still can almost reach 100%.And injected water volume and institute's heat content thereof still remain in the gaseous mixture, therefore, have still kept the thermal efficiency of this device, make this device can realize efficient, energy-conservation and the long-term safety operation.
