Abstract
The utility model relates to a device in pit that is used for oil well especially high moisture oil well to exploit: a double-action pump for oil pumping and water injection of a high water-cut well. The double-acting pump consists of an oil pumping valve seat body 1, a water injection valve seat body 5, a pump barrel 4, and a liquid discharge valve 2, a liquid suction valve 3, a water suction valve 6 and a water discharge valve 7 which are arranged in the pump barrel. The device is novel in design and simple in structure, skillfully combines the oil pumping part and the water injection part into a whole, can simplify the production link and consumption of an oil well, can realize the double functions of oil extraction and water injection in the same well, greatly reduces the production cost, improves the economic benefit, and is suitable for popularization and application.
Description
The utility model relates to a kind of particularly downhole hardware of high-water-cut oil-producing well exploitation of oil well that is used for.
After oil field development enters the middle and later periods, oil well successively by in low moisture mining phase transfer high moisture mining phase to.Along with the rising of crude oil water content, oilwell produced fluid amount constantly increases, and not only makes the oil extraction difficulty increase, and make be used for that oil extraction, collection are defeated, the expense of dehydration and production links such as sewage treatment, re-injection sharply increases.At present, because the on-the-spot extracting device of oil that is fit to the above-mentioned production characteristics of high water-cut well that lacks still adopts traditional mining type and downhole hardware, thereby be difficult to solve the problem that cost of production increases, economic benefit descends.
The purpose of this utility model is to provide a kind of oil extraction and produced-water reinjection is combined as a whole, thus the high water-cut well oil pumping water filling double-acting pump that can simplify the crude oil production process, reduce production costs greatly.
The utility model is to realize like this.This kind double-acting pump comprises oil pumping and water filling two large divisions.Wherein, the oil pumping part is made up of oil pumping valve seat body, imbibition valve, discharge opeing valve, and the water filling part is made up of water filling valve seat body, suction valve, draining valve, connects and separates with pump barrel therebetween.During use, with this double-acting pump with the oil pump tubular column G.I.H, wherein oil pumping part is positioned at upper wellbore production section top, and the water filling part is between pit shaft bottom interlayer and water layer, and the packet in order to packing production section and water layer is equipped with in the pump barrel lower end of water layer top.In the oil well production process, when pumping unit is up, horse head drives sucker rod, oil pump plunger piston is up, and at this moment, the pump barrel internal pressure of water filling part reduces, the draining valve is closed, the suction valve is opened, and pump barrel begins imbibition, and the discharge opeing valve of oil pumping part is opened, the imbibition valve is closed, and liquid is discharged into oil pipe and by lifting in the pump barrel.When pumping unit was descending, horse head drove the oil pumping pump rod, the oil well pump plug is descending, at this moment, liquid is compressed in the pump barrel of water filling part, and the suction valve is closed, and the water filling pump barrel begins discharge opeing, and the discharge opeing valve of oil pumping part is closed, and the imbibition valve is opened, and the oil pumping pump barrel begins imbibition.Through to-and-fro motion up and down, low wet crude above in the oil well is constantly given rise to ground, and simultaneously, following sewage is injected into the water layer of high permeability, not only replenish, slowed down the loss of stratum energy, and can save the expense that is used for the dehydration of crude oil and sewage treatment, re-injection.
The utility model modern design, simple in structure, utilize it dexterously high-water-cut oil-producing well oil pumping, water filling to be combined as a whole, both can simplify the oil well production link and expend, can realize the difunctional of same well oil extraction, water filling again, reduce production costs significantly, increase economic efficiency, be suitable for and apply.
Accompanying drawing is general structure of the present utility model and working condition schematic representation.Among the figure, label " 8 ", " 9 ", " 10 ", " 11 " are respectively oil well casing, production section, interlayer and water layer, and label " 12 " is a packet.
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
