Description
The utility model relates to a kind of oil field downhole oil extraction device, and the notes double fluid pump is adopted in particularly a kind of oil-water separation.
At present, conventional oil extraction pump is generally adopted in oil extraction, will inject water with output liquid extraction ground, can't realize the down-hole pre-separation of oil, water.Along with the prolongation in waterflooding extraction cycle, high water-cut stage during the oil field has entered, moisture increase in the oil reservoir, a large amount of moisture extraction had both increased the energy consumption in the recovery process, had increased ground again and had carried and the dehydration expense.Particularly deviating from water more than 60% needs after depth treatment, could non-pollution discharge.The oil field is minimizing ground release amount, selectively non-benefited layer re-injection down, and another has increased injection energy consumption and expense.
The purpose of this utility model provides a kind of oil-water separation and adopts the notes double fluid pump, and this pump can be realized the pre-separation of high water-content crude oil underground oil-water, and will divide dried up boosting to be recycled into the down-hole target zone, and isolated crude oil is evacuated to ground, reaches to adopt notes and carry out synchronously.
The utility model oil-water separation is adopted the notes double fluid pump and is comprised pump barrel, standing valve, traveling valve, plunger, and described pump barrel comprises the lifting pump barrel and the supercharging pump barrel of mutual sealing, and plunger comprises elevator pump plunger and suction booster plunger; The supercharging pump barrel connects oil-water separator, and oil-water separator has the tapering central passage, and the top has lateral incision, is respectively arranged with oil drainage hole, weep hole up and down; Promote pump barrel and communicate with oil drain passage, the supercharging pump barrel communicates with drainage channel, and supercharging pump barrel barrel has weep hole.
Oil-water separation of the present utility model is annotated and is adopted double-acting pump employing down-hole cyclone separator and oil-water separation multithread road, can realize effective pre-separation of downhole oil, water, carry on energy consumption and ground in the reduction recovery process, the dehydration expense, reduce ground sewage and handle energy consumption and expense, guarantee for environmental protection provides more reliably.
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 annotates for the utility model oil-water separation and adopts a kind of embodiment's of double-acting pump schematic representation.
Fig. 2 annotates the schematic representation of adopting the another kind of embodiment of double-acting pump for the utility model oil-water separation.
Fig. 3 annotates the schematic representation of the cyclone separator of adopting double-acting pump for the utility model oil-water separation.
As seen from Figure 1, the profit pre-separation is adopted lifting pump barrel 1 and the supercharging pump barrel 3 of annotating double fluid pump and is coupled to one up and down, promoting pump barrel 1 links to each other with oil drainage hole 23 by oil exit pipe 13, the standing valve that promotes pump barrel 1 is the side direction valve 5 that is arranged at the bottom, and supercharging pump barrel 3 links to each other with weep hole 24 by waste pipe 14; Elevator pump plunger 2 and suction booster plunger 4 are connected in series by oil pumping polish rod, and these oil pumping polish rod two ends are provided with the central duct 11 that has side opening 10, and supercharging pump barrel 3 is provided with and has weep hole 16.
As seen from Figure 2, the profit pre-separation is adopted lifting pump barrel and the supercharging pump barrel of annotating double fluid pump and is set to interior pump barrel 1 and outer pump barrel 2, elevator pump plunger and suction booster plunger are set to inner plunger 3 and outer plunger 4, outer plunger 4 sidewalls have weep hole 31, and inner plunger 3 links to each other with the oil drain passage 23 of oil-water separator 20 by plunger rod 14; Hollow rod 10, interior pump barrel 1 link to each other successively with outer plunger 4; Elevator pump standing valve 11 is arranged on the inner plunger 3, and the suction booster standing valve is the eccentric valve 12 that is arranged at outer pump barrel bottom, and the suction booster traveling valve is the ring-like valve 13 that is arranged at outer plunger 4 bottoms, and outer pump barrel is outside equipped with the outer tube 15 that has weep hole 16.
As seen from Figure 3, oil-water separator 20 is made up of liquid inlet joint 21, eddy flow auger 24, eddy flow conelet 23, cyclone tail tube 25, control flowing water mouth 26 5 parts successively.Can determine eddy flow auger, conelet and control flowing water mouth shape, size and size by indoor a large amount of waterpower experiments and calculating, can guarantee after its reasonable disposition that re-injection water reaches industry water filling standard.
Under strata pressure, highly aqueously in the oil reservoir enter oil-water separator 20 by liquid inlet joint 21, carry out the oil-water cyclone shunting, when carrying on the plunger, isolated oil enters the pump barrel lower chambers through oil exit pipe and side direction valve, and the water after separating enters down the pump barrel lower chambers through waste pipe and standing valve; When plunger is descending, oil in the last pump barrel then side opening by piston rod enters the upper plug chamber and is pumped to ground, water in the following pump barrel is then after lower plunger boosts, enter down the upper chamber of pump barrel by the side opening of piston rod, be injected in the water filling layer by the sealing of two packets through the weep hole of pump barrel down again.
Of particular note Fig. 1 can realize respectively adopting and pour down, adopts the purpose on making a bet.The target of separation after the utility model can also be realized boosting earlier, re-injection, back production.
