Description
The utility model relates to and is used for a kind of device that oil heating exploitation and pit shaft or oil pipe clean.
As everyone knows, in the petroleum reserves in the most of oil field of China, the viscous crude proportion increases day by day, and in all heavy oil reserves, can adopt part and only account for part, and remainder all can't be exploited with conventional because of big, the molten point of viscosity is high.At present heavy crude heat extraction uses the steam injection method in a large number, and the water vapour that is about to HTHP is delivered to well head through pipe network and injects the down-hole, with the viscous crude desaturation that heats up, uses the oil pumper extraction again.This mode is low owing to technical difficulty, extensive use at home and abroad.But owing to need the high voltage large-sized directly-heated type steam boiler of configuration and a large amount of transmission pipeline networks, capital expenditure is huge, and in case the point that recovers the oil is scrapped, complete equipment will leave unused and can't utilize again.Because the operating cost height, thermal efficiency low power consuming is big, and cost for oil production is high, and the flue gas that boiler produces all enters atmosphere, has both wasted a large amount of heat energy, again serious environment pollution.Obviously, this steam injection method is very undesirable.For this reason, taken up to study new steam generator abroad in recent years.The high-pressure combustion direct heat transfer formula downhole steam generator developed in the eighties of U.S. Rockwellinternational company for example.Such as former Soviet Union oil natural gas industry comprehensive automation research institute in the ground combustor of late nineteen eighties development.But because ins and outs disclose deficiency, above-mentioned information only is report.
The purpose of this utility model be to provide a kind of equipment light, can be with the change in oil recovery place mobile device, in this device, produce the mixture of water vapour and combustion gas with the mode of directly burning, with this mixture injection underground mining viscous crude.For this reason, require this device thermal efficiency height, the power consumption low, small investment and pollution-free.
Technical solution of the present utility model is as follows: promptly in comprising the ground gas steam generator of combustion and steam generating means, source of the gas, oil pump, water pump, motor, valve, measurement mechanism and control system, be provided with by divergent contour air inlet group section, tangential swirl formula swirler, the fuel injection nozzle that is positioned at the swirler center, igniter, be the burning zone of circular cone shape and be the burner that the cylindrical shape surface constitutes around the burner inner liner of cooling jacket; Be blender, the convergent contour exhaust group section that cylindrical shape inside is provided with turbulent device with the vaporization chamber that is cylindrical shape, the appearance of the coaxial setting of above-mentioned burner and the water injection nozzle that is arranged in the vaporization chamber constitutes vaporising device.Wherein, the fuel injection nozzle that is positioned at the swirler center can be the centrifugal nozzle of pressure type, also can be the pneumatic type nozzle.Tangential swirl plate in the swirler can be straight plate, also can be spiral plate.Igniter can be that the high energy electricity of direct-fire is chewed, also can be by housing, electricity chew, oil chews the indirect igniter that constitutes.The annular cooling water cover is made of with straight plate, spiral plate or pipe around burner inner liner respectively flame tube wall, outer wall.The water injection nozzle that is arranged in the vaporization chamber can be the centrifugal nozzle of pressure type that is positioned at the contrary airflow direction water spray in vaporization chamber center, also can be the centrifugal nozzle of pressure type that is positioned at vaporization chamber center downstream direction water spray, can also be the some spray booms that have aperture that radially are provided with along the vaporization chamber cross section.The turbulent device that internal mixer is provided with, can be bolted some porous plates perpendicular to the blender axis, also can be the crescent plate of bolted inverted arrangements successively perpendicular to the blender axis, can also by deflection cone respectively with along the blender cross section radially flabellum shape the fixing some spiral plates in the fixing some straight plate in two ends or two ends be set constitute.
The utility model is because reasonable in design, and the burning tissue is better, flame stabilization, and reliable operation, its thermal efficiency is up to more than 95%.And traditional injection steaming process, the thermal efficiency is the highest also only to be 85%.Compare with traditional injection steaming process, the thickened oil recovery rate is enhanced about more than once, and energy savings is over half.The utility model equipment is light, can change with the oil recovery well point to move.Because this device is for direct heat transfer, water vapour is that water and combustion gas are formed by directly mixing, no heat exchange steel pipe, thereby avoided the steam generator dissolved solid of current use to deposit and the booster phenomenon of bringing out, the huge maintenance cost that can save this respect.All these greatly reduce cost for oil production undoubtedly.Because the utility model all injects into well the waste gas of water vapour and the generation of burning back, thereby the discharging of fundamentally having stopped CO2 and N2 and sulfide has guaranteed non-environmental-pollution.When the utility model is made small portable, can also substitute the present on-the-spot boiler car that uses, carry out the cleaning of pit shaft and oil pipe.In a word, the utility model popularizing application prospect is very wide.
