Abstract
A nozzle for cleaning an oil and water well is applied in well cleanout construction in an oil field. the external thread of an upper joint is connected with an outer pipe; a locking ring is also connected on the external thread of the upper joint; the lower end surface of the locking ring is pressed on the upper end surface of the outer pipe; an annular step is disposed in the outer pipe; a lower plane bearing is disposed on the annular step of the outer pipe; a nozzle is disposed on the upper portion of the lower plane bearing, and is passed through the lower plane bearing; an upper plane bearing is disposed in the outer pipe, and disposed on the upper end of the nozzle; an inner cylinder is disposed on the upper portion of the upper plane bearing; the lower end surface of the inner cylinder is pressed on the upper plane bearing; the lower end surface of the upper joint is pressed on the upper end surface of the inner cylinder; inclined spray orifices are formed on the wall of the nozzle; the inclined spray orifices are tangential holes all in clockwise direction or all in anti-clockwise direction. The utility model achieves the advantages that; the nozzle is connected on the lower end of a tubular pile, can clean the wall of an oil and water well; achieves high flushing speed, good flushing performance and high efficiency; increases sand washing speed and prevents sand clamping and sand burying.
Description
Technical field
The utility model relates to oil field oil recovery, well workover technology field, particularly a kind of shower nozzle of the wash oil well borehole wall.
Background technology
At present, for the maintenance of oil-water well, basically all used clean-out service.In washing well process, all can use the well-flushing instrument.It is fairly simple usually that each oil field is used for the instrument of oil-water well well-flushing.See there are two kinds basically from type, a kind of is the sand washing drill bit of band nib; Another kind is the drifting instrument of using always.The mode of its flushing is single, has several open defects in the use: (1) is directly to flushing; (2) water consumption is big; (3) be prone to cause sand card sand to bury; (4) tube wall agllutination and borehole are not reached the flushing purpose.
The utility model content
The purpose of the utility model is: a kind of shower nozzle of wash oil well is provided, is connected the tubing string lower end, and the ability wash oil well borehole wall, flushing speed is fast in the wash oil well, the good efficient of flushing performance is high, prevent that sand card sand from burying, water consumption is little.Overcome the straight deficiency that present wash oil well exists to flushing.
The technical scheme that the utility model adopts is: the shower nozzle of wash oil well; Mainly form by top connection, stopping ring, outer tube, last plane bearing, lower plane bearing and shower nozzle; In the upper end of top connection the oil pipe internal thread is arranged, it is characterized in that: there is external screw thread the lower end in top connection, and the external screw thread through top connection is connected with outer tube; On the external screw thread of top connection, also be connected with the stopping ring, the stopping ring is on the annular inner wall screw thread to be arranged; Stopping ring lower surface is pressed in the upper surface of outer tube; A ring-shaped step is arranged in the outer tube, a lower plane bearing is arranged on the ring-shaped step in outer tube, on the top of lower plane bearing and pass the lower plane bearing shower nozzle is arranged; In outer tube and in the upper end of shower nozzle, plane bearing on is arranged, it is the inner core of annular that a cross section is arranged on the top of last plane bearing, and the lower surface of inner core is pressed on the plane bearing, and the lower surface of top connection is pressed on the upper surface of inner core; Described shower nozzle is that cylindrical lower part has the end; Oblique spray orifice is arranged on the wall of shower nozzle; Tiltedly spray orifice is a tangential hole, and tiltedly the direction of spray orifice all is clockwise or counterclockwise.
Connect tubing string on top connection top, with the shower nozzle G.I.H of wash oil well.Water under high pressure is injected on ground, and water under high pressure gets into shower nozzle through top connection, inner core, and from the oblique spray orifice ejection of shower nozzle, because tiltedly the direction of spray orifice is consistent, the water under high pressure reaction force promotes the shower nozzle rotation, and water under high pressure cleans the well inwall.
In order to improve sealing, between outer tube and inner core, sealing ring is arranged, the O RunddichtringO is arranged between outer tube and shower nozzle.
The beneficial effect of the utility model: the shower nozzle of the utility model wash oil well, be connected the tubing string lower end, the ability wash oil well borehole wall, flushing speed is fast in the wash oil well, the good efficient of flushing performance is high; Improved sand washing speed, prevented that sand card sand from burying; Solved the difficult problem that conventional sand washing can't be washed the borehole wall and borehole; Water consumption is little.
Description of drawings
Fig. 1 is the nozzle structure generalized section of the utility model wash oil well.
Among the figure, 1-top connection, 2-stopping ring, 3-outer tube, 4-inner core, the last plane bearing of 5-, 6-lower plane bearing, 7-O RunddichtringO, 8-shower nozzle, the oblique spray orifice of 9-.
The specific embodiment
Embodiment 1: the shower nozzle with a wash oil well is an example, and the utility model is done further explain.
Consult Fig. 1.The shower nozzle of the utility model wash oil well mainly is made up of top connection 1, stopping ring 2, outer tube 3, last plane bearing 5, lower plane bearing 6 and shower nozzle 8, in the upper end of top connection 1 the oil pipe internal thread is arranged.There is external screw thread lower end in top connection 1; External screw thread through top connection 1 is connected with outer tube 3, on the external screw thread of top connection 1, also is connected with a stopping ring 2, and stopping ring 2 has screw thread on the annular inner wall; Stopping ring 2 plays the effect of stopping nut, prevents thread looseness between top connection 1 and the outer tube 3.Stopping ring 2 lower surfaces are pressed in the upper surface of outer tube 3.A ring-shaped step is arranged in the outer tube 3, a lower plane bearing 6 is arranged on the ring-shaped step in outer tube 3, on the top of lower plane bearing 6 and pass lower plane bearing 6 shower nozzle 8 is arranged.There is an outwards ring-shaped step of protrusion the upper end of shower nozzle 8.In outer tube 3 and in the upper end of shower nozzle 8, plane bearing 5 on is arranged, the inner core 4 that on the top of last plane bearing 5 cross section to be arranged be annular, the lower surface of inner core 4 is pressed on the plane bearing 5, and the lower surface of top connection 1 is pressed on the upper surface of inner core 4.Described shower nozzle 8 has the end for cylindrical lower part; Oblique spray orifice 9 is arranged on the wall of shower nozzle 8; Tiltedly spray orifice 9 is a tangential hole, and tiltedly the direction of spray orifice 9 all is counterclockwise.A sealing ring is arranged between outer tube 3 and inner core 4, between outer tube 3 and shower nozzle 9, O RunddichtringO 7 is arranged.
