Abstract
Disclosed is a thermal well-flushing fluid director which is provided with a lower fluid direction cylinder. The thermal well-flushing fluid director is characterized in that the upper end of the lower fluid direction cylinder is connected with a fluid direction bushing through jackscrew support sleeves circumferentially and uniformly distributed and fixed, the upper portion of the fluid direction bushing is fixedly connected with a rubber cone cylinder by means of vulcanization, the maximum outer edge of the rubber cone cylinder is in contact with the inner wall of a bushing, a micro clearance is formed from the inner end of each jackscrew support sleeve to the outer wall of an oil tube, an inner thread is arranged on each jackscrew support sleeve, an upper jackscrew is connected in each jackscrew support sleeve in a threaded manner, and the inner end of each upper jackscrew is in contact with the outer wall of the oil tube; the lower end of the lower fluid direction cylinder is in threaded connection with lower jackscrews in a circumferential even distribution manner, and the inner end of each lower jackscrew is in contact with the outer wall of the oil tube. By the thermal well-flushing fluid director, paraffin removal effect of the oil tube is improved remarkably, and energy and water are saved.
Description
Technical field
The invention belongs to a kind of oil extraction in oil field device, particularly a kind of hot clean-up well air deflector.
Background technology
In oil recovery process, the interior wax deposition phenomenon existed in various degree of the oil pipe of oil well, sleeve pipe, continuous wax deposits causes oil well pump wax card, oil well output significantly declines, and adds the expense of oil producing operation, even causes stopping production.
Hot clean-up well technology is a kind of wax removal technology of common employing in the wax removal and inhibition work of domestic and international oil field, the casing annulus that the method will be squeezed into pump after the heating liquid on the tank car of ground in well by boiler, the liquid of this heating is by entering in oil pipe by pumping hole after casing annulus, wax on tube inner wall is melted into liquid state, and be carried and return out well head, but the heat of liquid is by the heat transfer of sleeve pipe in hot clean-up well process, most heat is by formation absorption, heat waste is higher, simultaneously because the cross-sectional flow area of casing annulus is larger, the flow rate of liquid of hot clean-up well is very fast, wax removal effect is had a greatly reduced quality.
The object of this invention is to provide a kind of hot clean-up well guiding device, improve the wax removal effect of oil pipe, energy-saving and water-saving.
Technical scheme provided by the invention is: arrange a lower guide shell, it is characterized in that: the top of lower guide shell is fixedly connected with rubber cone cylinder by sulfuration, the maximum outer rim contact sleeve inside pipe wall of rubber cone cylinder; The upper and lower end of lower guide shell is respectively uniformly distributed along the circumference to be threaded three and goes up jackscrew, three lower jackscrews, and end in contact oil-pipe external wall in upper and lower jackscrew, makes lower guide shell locate.
Technique effect of the present invention: when hot clean-up well, heating liquid flows along oil-pipe external wall slowly along the annular space of this device inwall and oil-pipe external wall, because this device significantly increases liquid at the flow time needing wax removal position, make to need the oil pipe of wax removal position to significantly improve wax removal effect, and serve effect that is energy-conservation, water saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
See Fig. 1, concrete structure is as follows: arrange a lower guide shell 4, the top of lower guide shell 4 is fixedly connected with rubber cone cylinder 3 by sulfuration, the maximum outer rim contact sleeve A inwall of rubber cone cylinder 3; The upper and lower end of lower guide shell 4 is respectively uniformly distributed along the circumference to be threaded three and goes up jackscrew 2-1, three lower jackscrew 2-2, and three upper jackscrew 2-1 and three lower jackscrew 2-2 are circumferentially evenly staggering; End in contact oil pipe B outer wall in upper and lower jackscrew, makes lower guide shell 4 locate.
Operating principle
Close to well head and need the oil pipe B of hot clean-up well water conservancy diversion position installs hot clean-up well guiding device, when hot clean-up well, during the rubber cone cylinder 3 of liquid by lower guide shell 4 upper end, lower guide shell 4 inwall is adjacent to by rubber cone cylinder 3, the annular space C of liquid runs down rubber cone cylinder 3 inwall and oil pipe B outer wall slowly enters, downwards in oil pipe, finally return well head.Because the annular space C between this device of liquid runs down and oil pipe B flows along oil-pipe external wall slowly, liquid is made to significantly increase in the time of staying needing wax removal position, make to need the oil pipe of wax removal position to improve wax removal effect, and serve the effect of energy-saving and water-saving.
Claims (1)
1. a hot clean-up well air deflector, a lower guide shell is set, it is characterized in that: the upper end of lower guide shell connects water conservancy diversion body by the jackscrew support set that circumference uniform distribution is fixing, the top of water conservancy diversion body is fixedly connected with rubber cone cylinder by sulfuration, the maximum outer rim contact sleeve inside pipe wall of rubber cone cylinder, the inner distance oil-pipe external wall of jackscrew support set has slight clearance, and jackscrew support set arranges internal thread, upper jackscrew is threaded in it, end in contact oil-pipe external wall in upper jackscrew; The lower jackscrew that the lower end edge circumference uniform distribution of lower guide shell is threaded, end in contact oil-pipe external wall in lower jackscrew.
