Abstract
A kind of throw-in type cavity ejector.Mainly solve the problems, such as existing tube inner wall dirt matter clear up not in time will lead to oil well liquid output amount reduce, even fouling cause the reductions such as holddown influence oil field production.It is connect afterwards at least one fimbriatum (3) it is characterized by: drive rod (2) upper end passes through sleeve (1), the surface of the fimbriatum (3) is equipped with multiple axial gaps, the fimbriatum (3) is flexible steel disc body, is accommodated in sleeve (1) after compression.The throw-in type cavity ejector can clear up the dirty matter of tube inner wall in time, and can quickly recycle, Reusability.
Description
Technical field
The present invention relates to oil field equipment field, specifically a kind of throw-in type cavity ejector.
Background technique
In the production of oil field, the inner wall of oil pipe often adheres to a large amount of dirty matter, especially ternary composite driving well construction phenomenon
Very serious, if cleared up not in time, the liquid outlet quantity that will lead to oil well is reduced, and seriously affects oil field normal work.
Summary of the invention
It will lead to that oil well liquid output amount reduces, even fouling causes to overcome existing tube inner wall dirt matter to clear up not in time
The reductions such as holddown influence the deficiency of oil field production, and the present invention provides a kind of throw-in type cavity ejector, the throw-in type cavitation jet
Device can clear up the dirty matter of tube inner wall in time, and can quickly recycle, Reusability.
The technical scheme is that a kind of throw-in type cavity ejector, including drive rod, the drive rod upper end pass through
It is connect after sleeve at least one fimbriatum, the surface of the fimbriatum is equipped with multiple axial gaps, and the fimbriatum is soft
Annealed steel sheet body is accommodated in sleeve after compression.
The side wall of the sleeve is along the circumferential direction laid with several through-holes.
The lower part of the sleeve is equipped with the first conical section that outer profile from top to bottom successively reduces, and the lower end of drive rod is equipped with
The second conical section that outer profile from top to bottom successively reduces, and the taper of the first conical section outer surface and the second conical section outer surface
Taper it is identical, the second conical section upper end of the drive rod is equipped with boss, and sleeve lower end is withstood on boss.
The fimbriatum includes nut and several spring leafs, and the spring leaf along the circumferential direction uniformly forms one
From top to bottom successively the hollow cone table of flaring, the upper end of the hollow cone table are fixed on nut outer profile, nut suit
In the upper end of drive rod.
It is overlapped mutually, and has the gap between two neighboring spring leaf.
The invention has the following beneficial effects: due to taking above scheme, which can carry out the inner wall of oil pipe
Cleaning comprehensively removes the greasy dirt for being attached to oil pumping inside pipe wall and various dirty matter, it is ensured that the normal operation of oil field production；Body of the present invention
Product is small, and structure is simple, convenient to use, and can quickly recycle, Reusability, and the cleaning charge of oil pipe is greatly saved.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the cross-sectional view of the A-A along Fig. 1.
1- sleeve in figure, 2- drive rod, 3- fimbriatum, 1-1- through-hole, the first conical section of 1-2-, the second conical section of 2-1-,
3-1- blade, 3-2- nut.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
As shown in Fig. 1, Fig. 2, a kind of throw-in type cavity ejector, including drive rod 2, after 2 upper end of drive rod passes through sleeve 1
It is connect at least one fimbriatum 3, the surface of the fimbriatum 3 is equipped with multiple axial gaps, and 3 outer diameter of fimbriatum is less than
1 internal diameter of sleeve, and fimbriatum 3 is flexible steel disc body, can be accommodated in sleeve 1 when driving 2 moves down after compression.Driving
Bar 2, which moves up, can make the fimbriatum 3 shunk stretch out and open out of sleeve 1 upper end.The side wall of the sleeve 1 is circumferentially square
To several through-holes 1-1 is laid with, it can prevent from generating negative-pressure adsorption fimbriatum 3 in sleeve 1 in this way, lead to 3 nothing of fimbriatum
Method is stretched out out of sleeve 1.
The lower part of the sleeve 1 is equipped with the first conical section 1-2 for from top to bottom successively reducing of outer profile, under drive rod 2
End is equipped with the second conical section 2-1 that outer profile from top to bottom successively reduces, and the taper and second of the first outer surface conical section 1-2
The taper of the outer surface conical section 2-1 is identical, and the second upper end conical section 2-1 of the drive rod 2 is equipped with boss, and 1 lower end of sleeve can
It, can be to avoid drive rod 2 by being slipped in sleeve 1 to withstand on boss.
The fimbriatum 3 can be to be multiple, and each fimbriatum 3 includes nut 3-2 and several spring leafs 3-1, institute
It states spring leaf 3-1 and along the circumferential direction uniformly forms an outer profile successively hollow cone table of flaring from top to bottom, and is adjacent
It is overlapped mutually, and has the gap between two spring leaf 3-1.The upper end of the hollow cone table is fixed on nut 3-2, nut
3-2 is sleeved on the upper end of drive rod 2.Multiple fimbriatums 3 are from top to bottom connected in turn on drive rod 2.
When work, first sucker rod is taken out out of oil pipe, then pull downward on drive rod 2, fimbriatum 3 is made to be accommodated in sleeve
In 1；Ejector throwing is put into oil pick-up tube, after ejector reaches oil pumping bottom of the tube, the lower end of drive rod 2 touches pumping
Behind oil pipe bottom surface, fimbriatum 3 is released sleeve 1 since effect of inertia cylinder 1 continues to move down by 2 stop motion of drive rod.
By water pump, into oil pick-up tube, high pressure water is injected in bottom at this time, and water flow impacts the lower surface of fimbriatum 3 from the bottom to top, pushes entire
Ejector moves up, while water flow is sprayed by the gap between two neighboring spring leaf 3-1 and impacts and clean oil pick-up tube
Inner wall, when ejector completes the cleaning of oil pumping inside pipe wall when bottom outreaches out of oil pick-up tube.
