Abstract
A sand control screw pump oil production unit belongs to the petroleum machinery product, which is an improved ground drive screw pump oil production unit applied in oil extraction to mainly resolve the sand blocking deficiency. A sand guide device installed on the rotor upper part of the unit is linked to a sucker rod. A sand guide tube is installed on the outside of the rotor, and a separation joint is also installed and connected on the lower part of the rotor. A riffling tube is installed on the lower part of the separation joint, and a tubing anchor is installed on the outside of the riffling tube. With the unit, the failure of sand blocking can be resolved and prevented so that the screw rod can work normally with less maintenance. The crude oil cost is reduced. Relatively the economic return is increased.
Description
One, technical field: the utility model belongs to the petroleum machinery product, relates to the ground driving screw pump that a kind of improved crude oil extraction uses and recovers the oil idle.
Two, background technology: existing ground driving screw pump extracting device of oil, form by tubing anchor, screw pump stator, oil pipe, well head and rotor, sucker rod, surface drive under the pump, come with some shortcomings in actual the use, when the exploitation sandy crude, because of sand than great, often be stored in the above oil pipe of rotor, when unexpected power failure, sand sinks sucker rod is buried stifled, it can not be rotated again, have only operation well workover again, this just influences crude output, has increased the cost of crude oil.
Three, summary of the invention: the purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of sand control card screw pump oil production device is provided.
Its primary structure is like this, on the rotor top of this device a kind of sand device of leading is installed, and leads the sand device and is connected with sucker rod, at a kind of sand-guiding tube of the outside installation of stator, and at stator bottom installation connection separating joint, separating joint bottom dress sand sediment pipe, sand sediment pipe is installed tubing anchor outward.When surface drive was urged to sucker rod to rotor rotation, the fluid in the oil reservoir (comprising crude oil, water, gas and sand etc.) was through separating joint-pump-oil pipe ground.Wherein sand sinks in oil pipe naturally, and under the effect of leading the sand device, through sand-guiding tube-separating joint sand sediment pipe, it is stifled just to have solved the sand card effectively, makes screw pump normal operation work.
There is this device just to solve the fault that prevents that the sand card is stifled, makes the screw pump operate as normal, reduce maintenance, reduce crude oil cost, improved economic benefit relatively.
Four, description of drawings:
Accompanying drawing is a sand control card screw pump oil production device structure principle chart.
Explain: 1, surface drive 2, oil pipe 3, lead the sand device, its architectural feature is that top is little, the bullet shape that the bottom is big, be convenient to silt particle 4, stator 5, rotor 6, separating joint 7, tubing anchor 8, oil reservoir 9, sand sediment pipe and it is characterized in that the lower end bottom lock, be convenient to accumulate sand 10, liquid inlet, stratum 11, sand-guiding tube, principal character is to be equipped with in the sand-guiding tube to lead sand device 3 and stator 4 and rotor 512, sucker rod 13, sleeve pipe
Five, the specific embodiment: as seen from the figure, the drive unit 1 of this device connects sucker rod 12 and leads sand device 3, lead sand device 3 and connect stator 4 and rotor 5, stator 4 outside sand-guiding tube 11, junction, stator 4 sand-guiding tubes, the 11 bottom connection separating joints 6 installed, separating joint 6 bottoms connect sand sediment pipe 9, sand sediment pipe 9 is fixed on sleeve pipe 13 by tubing anchor 7, and the top of sand-guiding tube 11 connects oil pipe 12 and to surface drive 1/ sand-guiding tube 11 sand-guiding tube 3 and stator 4 and rotor 5 is installed.When ground drive unit 1 driving sucker rod 12, when leading sand device 3 and rotor 5 rotations, stratum liquid is after liquid inlet, stratum 10 is to the stator 4, enter arrival ground in the oil pipe 2 through leading sand device 3 outsides, wherein sand sinks under the effect of leading sand device 3 under the nature in oil pipe 2, arrive in the sand sediment pipe 9 through sand-guiding tube 11 to separating joint 6, solved the stifled difficult problem of screw pump sand card thus, prolonged this pump and used the production cycle, improve service efficiency, reduced the cost of production of crude oil naturally.
