The utility model has all the equipments needed by thermochemical oil extracting liquid-injecting works installed on one automobile, which is convenient to transport, thereby especially applicable to be utilized in oil field where the transporting condition is not that well.
Description
Technical field
The utility model belongs to the ancillary service of heating power chemical recovery, is a kind of heating power chemical recovery injecting locomotive specifically.
Background technology
Worldwide, the reserves of viscous crude and super viscous crude are appreciable, and according to existing explored reserves, greatly about 8,630 hundred million tons, it is greater than the existing reserves of conventional crude.Therefore, it is significant to develop these resources.A distinguishing feature of heavy crude reservoir is, viscosity is very high under formation condition, and density is big, and fluid ability is poor, and steam is injected oil reservoir, and the heating oil reservoir is a main method of production of heavy oil reservoir.Steam reduces the viscosity of viscous crude, makes it obtain certain fluidity, helps gathering of crude oil.This is called as steam soak.But steam soak is through after several cycles, and strata pressure descends, and the cycle water recovery rate is low, and near the water saturation the shaft bottom increases, and drainage period prolongs with the increase of the round of handling up, and oil production descends.The heating power chemical recovery proposes under such background, and it comprises leading dose, emulsifier with chemical active agent, dispersing agents etc. inject producing well simultaneously according to different needs and steam, make oil-gas ratio, the speed of gathering, the degree of gathering, water recovery rate all is improved largely.Yet this technology was at the experimental stage always in the past, did not have supporting special-purpose injecting equipment, caused operating difficulties, inefficiency.
Summary of the invention
The purpose of this utility model is exactly in order to fill up this blank, arrange the characteristics of disperseing according to producing well, a kind of heating power chemical recovery injecting locomotive is provided, with employed device assembles in one, be placed on the mobile tractor, be particularly suitable for the on-the-spot poor traffic condition in oil field, be convenient between different well locations and different block, move and operation.
The purpose of this utility model is achieved in that it comprises vehicle frame, on vehicle frame, be provided with box body, it is characterized in that the injecting device is installed in the box body, the injecting device comprises the medicine-chest that is provided with the splendid attire medicament, and mixer and heater are installed in the medicine-chest, and medicine-chest is provided with delivery outlet, delivery outlet links to each other with the inlet of high-pressure pump by low pressure line, the delivery outlet of high-pressure pump is connected with pressure duct, is linked into the down-hole, and electro connecting pressure gauge and overflow valve are installed on pressure duct.
The utility model is installed in heating power chemical recovery injecting devices needed on one chassis, and is mobile more convenient, so be particularly suitable for the on-the-spot use in the poor oil field of traffic condition.Next is the reasonability of the utility model design.It is provided with two high pressure proportioning pumps at least, can regulate at any time to inject and keep rational quantity, be used alternatingly, be provided with the sewage draining exit of high-low pressure sewage draining exit and medicine-chest simultaneously, guaranteed the blowdown under each condition, guaranteed the stability of injecting, particularly the unidirectional non retern valve of She Zhiing has prevented the too high backflow that causes of borehole pressure.
Description of drawings
Fig. 1 is the interior layout vertical view of the car of heating power chemical recovery injecting locomotive of the present utility model.
Fig. 2 is a lateral plan of the present utility model.
Fig. 3 is mounted in the schematic diagram of the injecting device in the box body.
The specific embodiment
The utility model is described in more detail below in conjunction with specific embodiment and accompanying drawing thereof.
By illustrated in figures 1 and 2, the 12nd, vehicle frame, vehicle frame of the present utility model can be the hitch frames by the motor vehicle traction shown in the figure, also can be the vehicle frames that has the motor vehicle of power set.Box body 13 is installed on vehicle frame 12, and the injecting device is arranged in the box body.By Fig. 1 and shown in Figure 3.It comprises the medicine-chest 11 that is arranged on the box body front portion, and agitator 8 and heater 6 are installed in medicine-chest, and medicine-chest is provided with delivery outlet and is equipped with and filters suction nozzle 25.The medicine-chest bottom is provided with medicine-chest sewage draining exit 26.Delivery outlet at medicine-chest is connected by the input port of low pressure line with two high-pressure pumps 1, and for easy to use, low pressure line comprises low pressure hard tube 14 and low-pressure hose 15, is provided with low pressure sewage draining exit 5 on low pressure line.Infrared rays heating panel 2 is installed in the box body, and the delivery outlet of high-pressure pump is connected to the down-hole by pressure duct, in the outlet 4 of pressure duct one way valve 27 is housed.Comprise high-pressure hose 18 and hard tube 19 in the pressure duct.Pressure meter 20 and electro connecting pressure gauge 21 are installed on pressure duct, overflow valve 22 is installed simultaneously, overflow valve 22 also can be as high pressure sewage draining exit 3.For the needs of operating, between the delivery outlet of high-pressure pump and medicine-chest, be provided with return line 24, and pressure duct is provided with angle valve 23.
9 is electrical instrumentation dishes among the figure, the 10th, and tire 7 is hangers of vehicle frame.
Basic functional principle of the present utility model is: injecting adds medicine-chest, after heater heating and mixer stirring, enter high-pressure pump by filtering suction nozzle through low pressure line, open high pressure valve, be in injecting under the high pressure and converge together at well head and high steam by pressure duct and unidirectional non retern valve and inject into well.If surpass operating pressure, then electro connecting pressure gauge action, the shutdown of cutting off the electricity supply, injecting is excessive by overflow valve.
