Abstract
The invention discloses an auxiliary pumping device for oil extraction. The device comprises three sections of pipe bodies. The first section of pipe body is an oil inlet pipe (1), with its pipe wall being provided with a plurality of oil inlet holes (12); the second section of pipe body is an oil conducting pipe (2); and the third section of pipe body is an oil outlet pipe (3); a plurality of cross sections inside the second and the third sections of pipe bodies is respectively provided with meshes. The three sections of pipe bodies are sequentially connected by screw threads. The three sections of pipe bodies and the meshes are all made of J55 or N80 steels. With the auxiliary pumping device for the oil extraction, the formation of wax blockage and scale blockage on an oil-well pump, a sucker rod and an oil-well tube wall can be reduced. The auxiliary is applicable to the production of a conventional oil-water well, and is also applicable to waxing prevention, anti-corrosion and anti-scaling of a ground pipeline of a concentrated oil-gas-water transmission station, accordingly preventing and treating the waxing and scaling of the oil-water well, thereby saving plenty of working time and cost.
Description
Technical field
The invention belongs to technical field of petroleum extraction, what be specifically related to a kind of recover petroleum helps picking device.
Background technology
In oil extraction in oil field development process, wet crude there occurs very large change owing to comparing temperature, pressure oil gas water three phase in the earth formation in the wellbore, the paraffin in profit component, colloid, asphalitine, the sulfate of calcium magnesium barium strontium, carbonate is made very easily to separate out and condense on oil well pump, sucker rod, oil pumping tube wall, cause wax card, dirt card, production can not normally be carried out, and is ubiquitous phenomenon in the development late stage feed flow deficiency of the saturating oil reservoir of low pressure and low permeability in addition.For addressing this problem, the way usually adopted is:
1, workover treatment inspection pump more replace tubes bar pump
2, frequent hot washing oil wells
3, pickling oil well
4, artificial or mechanical paraffin cutting
But have also discovered some problems in process application process at the scene, be mainly manifested in:
(1), well workover labour intensity is large, it is long to account for the product time, costly.
(2), well-flushing costly, oil well bottom is easily damaged by well-flushing night, recover output slow.
(3) labour intensity such as paraffin cutting, pipe cleaning is large, and operating cost is high and have the hidden danger causing junk in well.
(4) pickling has corrosiveness to oil carbon steel pipeline well, affects oil well effective economic life.
(5) there is low-pressure area in the import department of oil well pump, cause oil well pump import department feed flow to occur labile state.
Summary of the invention
Problem to be solved by this invention be to provide a kind of alleviate in oil exploitation process oil well pump, sucker rod, oil pumping tube wall cause wax card, recover petroleum that dirt card is formed help picking device.
The technical solution adopted in the present invention is: a kind of recover petroleum help picking device, this device comprises three sections of bodys, first paragraph body is oil inlet pipe, its tube wall is provided with several fuel feed holes, second segment body is oil pipe, several cross sections of inner chamber of its pipe establish mesh sheet respectively, 3rd section of body is flowline, the oil-out of this flowline is connected with oil well pump, described flowline is sub-bell formula body, several cross sections in this body establish mesh sheet respectively, described oil inlet pipe, oil pipe, flowline three sections of bodys pass through screwed connection successively, described oil inlet pipe, oil pipe, flowline three sections of bodys and mesh sheet are made by J55 or N80 steel.
As a modification of the present invention: be equipped with screw thread on the inwall of described oil pipe and the fuel-displaced body of sub-bell formula, described mesh sheet is placed in the inner chamber of oil pipe and sub-bell formula flowline respectively by screw thread.
In oil exploitation process, the present invention instead of common oil pick-up tube, and oil inlet pipe extend in the required oil reservoir exploited and carries out oil suction, and the oil-out of flowline is connected with oil well pump.Due to the oil pick-up tube that the present invention adopts three sections of bodys to be connected to form, multiple mesh sheet is equipped with in oil pipe and flowline, which increase the contact area of oil water mixture and the oil pick-up tube of exploiting out, the oil pick-up tube made to make steel and oil water mixture fully contact and react, degrade paraffin, colloid, asphalitine, the sulfate of calcium magnesium barium strontium, carbonate is separated out and condensation, avoids the wax card on oil well pump, sucker rod, oil pumping tube wall and dirt card.The present invention helps picking device to be both applicable to the production of conventional oil-water well, also the surface line wax control anti-corrosion anti-scale of oil gas water gathering station is applicable to, for the oil well of feed flow deficiency, the oil-water well for easy wax deposition fouling carries out preventing and treating and processing, thus saves a large amount of activity duration and expense.
