The present invention relates to the injection distribution system that tertiary oil recovery drives thing.
In the tertiary oil production in oil field process, all need in oil well perfusion polymer or compound oil could be displaced, and the slaking of polymer or compound is an important step, slaking mode difference is directly connected to the difficulty or ease that how much reach the daily management maintenance of equipment investment, and existing slaking mode is to adopt the slaking jar to carry out slaking.Be about to polymer or compound and enter the slaking jar after the mixing, in the slaking jar, stir more than two hours, after polymer and the abundant slaking of compound, be transported to each preparation station by outer defeated screw pump again and inject through disperseing.There is the shortcoming that the quantity that needs the slaking jar is many, flow process is complicated, equipment investment is big, the line service amount is big, operating cost is high in this slaking mode.
The objective of the invention is to design the injection distribution system that a kind of tertiary oil recovery polymer flooding and ternary complex drive, this system has cancelled the slaking jar, in the pipeline transportation process, realize slaking, so it should have the characteristics that equipment investment is few, flow process is simple, maintenance workload is little, operating cost is low.
The present invention realizes its goal of the invention by following mode: the injection distribution system of polymer flooding comprises dry powder hopper 1, spiral blanking device 2, blast fan 3, dispersal device 4, switch board 5, clear water storage tank 6, pump 7, surge tank 9, defeated screw pump 10, conveyance conduit 12, coarse filter 13, fine filter 14, storage tank 15, injection pump 16 outward.The arrival end of spiral blanking device 2 is connected with the outlet of dry powder hopper 1, and the outlet of spiral blanking device 2 is connected with the inlet of blast fan 3 and dispersal device 4.The arrival end of pump 7 is connected with clear water storage tank 6, the port of export of pump 7 is connected with the inlet of dispersal device 4, switch board 5 is connected with dispersal device 4, carry screw pump 18 in the dispersal device 4, the port of export of the screw pump 18 of dispersal device 4 is connected with the arrival end of surge tank 9, the port of export of surge tank 9 is connected with the arrival end of outer defeated screw pump 10, one end of the outlet termination conveyance conduit 12 of outer defeated screw pump 10, one end of another termination coarse filter 13 of conveyance conduit 12, one end of another termination fine filter 14 of coarse filter 13, the inlet of another termination storage tank 15 of fine filter 14, the outlet of storage tank 15 connects the arrival end of injection pump 16, the outlet termination oil field shaft mouth 23 of injection pump 16.
On the injection distribution system of polymer flooding, increase again alkali storage tank 19, surfactant storage tank 20, pump 21, outside defeated screw pump 22 promptly become the injection distribution system that ternary complex drives.The inlet of pump 21 is connected with the outlet of alkali storage tank 19, and the port of export of pump 21 is connected with the inlet of surge tank 9, and the arrival end of defeated screw pump 22 is connected with the outlet of surfactant storage tank 20 outward, and the outlet of defeated screw pump 22 outward is connected with the inlet of surge tank 9.
The present invention is owing to cancelled the slaking jar, make polymer flooding and ternary complex drive slaking in conveying pipe, 2 hours curing times have been saved, a large amount of power consumptions of agitator day-to-day operation in the slaking jar have also been saved, especially the equipment investment and the maintenance operation overhead cost of a large amount of slaking jars have been saved, only with regard to a medium-size station, just can save 6,000,000 yuans of gross investments.And the slaking effect does not reduce again.Pipeline slaking has simultaneously reduced the degraded of polymer, thereby helps reducing the viscosity loss of whole system.Injection distribution system of the present invention can be widely used in tertiary oil production in oil field and drive in the injection distribution system of thing.
