Abstract
The utility model provides a hydraulic auto-rotation jet head for washing a well. The hydraulic auto-rotation jet head comprises a jet head assembly, independent spray nozzles, a central pipe, a speed-limiting mechanism, a non-return valve and the like, and has the technical characteristics that a threaded holes is formed in a specific position of the jet head; the spray nozzle is mounted in the threaded hole through threaded connection; rolling bearings are mounted at two ends of the central pipe, so that the central pipe serves as a rotation shaft while conveying liquid; the speed-limiting mechanism on the rotation shaft realizes centrifugal speed limitation through a friction block; the central pipe and the outer pipe form a cavity in a surrounding manner; a sleeve, which can be used for not only fixing a bearing but also being rubbed with the friction block to generate friction resistance, is mounted on the inner wall of the outer cylinder; and the non-return valve can be used for preventing the backflow of the liquid, so as to avoid accidents or damage of a tool. The structural principle of the hydraulic auto-rotation jet head is simple; and during the work of the hydraulic auto-rotation jet head , high-pressure liquid flows through the spray nozzles in different directions so as to form jet flows in different directions, the jet head is driven to rotate fast through the recoil strength of lateral jet flows, and a rotational flow field is formed in the air in an annular manner, so as to suspend sand and impurities, which improves the sand removing efficiency and the well washing efficiency of a horizontal well.
Description
Technical field
The utility model relates to the hydraulic spinning commentaries on classics shower nozzle that a kind of well-flushing is used, and is mainly used in the sand washing de-plugging of horizontal well, is a kind of special downhole tool.
Background technology
Horizontal well is domestic novel DP technology technology; It can increase the contact area of well and oil reservoir, reduces filtrational resistance, improves the whole development effect in oil field; Along with applying of this technology, the sand control and the sand washing de-plugging of net horizontal section also become particularly important.
On stream, prevent that sand production in oil from being to keep a key technology of oil field ordinary production, even but take sand control measure for the oil-water well of serious sanding formation, can not guarantee steady in a long-term production.For the well that sand control lost efficacy, if the liquid in the well can not all be taken sand out of ground, sand will deposit gradually in the well, and the sand post increases, and stops up oil discharge passage, increases flow resistance, makes the oil well underproduction even stopping production.Can damage underground equipment simultaneously and cause down-hole sand card accident, therefore something must be done to removes long-pending sand.Removing long-pending sand adopts hydraulic sand washing usually and drags for two kinds of ways of sand.Drag for sand and generally be applied to the lower oil well of pressure, using the widest is hydraulic sand washing.
Because the particularity of horizontal well casing programme; Compare with the straight well sand washing, there is following problem in the horizontal well sand washing process: owing to need the well section of flushing very long, especially flushing fluid is low in the prop-carrying capacity of net horizontal section and lower curved section; Therefore the easy sedimentation of sand grains; Be difficult for having been dashed and having removed totally, and when termination of pumping, be easy to form sand bridge, cause the sand card accident in the sand washing process in the high angle hole section.
Summary of the invention
The purpose of the utility model is that the hydraulic spinning that provides a kind of well-flushing to use changes shower nozzle; This shower nozzle utilizes the jet recoil strength of high-pressure water jet to make the shower nozzle rotation; Utilize the centrifugal speed limit principle of brake pad to control the rotary speed of shower nozzle, form good eddy flow field, sand suspension is got up; Overcome the problem that exists in the horizontal well sand washing process with this, improved the efficient of horizontal well sand-flushing greatly.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of well-flushing is with waterpower spinning shower nozzle, mainly by one way valve, central tube, speed limiting mechanism, shower nozzle assembly, independently nozzle constitutes.It is characterized in that: one way valve and urceolus are through being threaded together, and central tube relies on rolling bearing to be fixed in urceolus inside, form through felt and oil sealing in the end of central tube to seal in case the leakage of solution stopping body; Speed limiting mechanism is made up of axle sleeve, four brake pads, sleeves jointly; The axle sleeve of a fluting is installed on the central tube, is put brake pad in the groove, sleeve relies on interference fit to be fixed in urceolus inside; When shower nozzle drives the central tube rotation; Under action of centrifugal force, brake pad and sleeve mutual friction mutually produce the speed limit effect; Shower nozzle also is to link to each other with central tube through being threaded; Nozzle adopts independently nozzle arrangements; Be installed on the shower nozzle through being threaded, in the back after installing two on the circumferential position at nozzle installing hole place to nozzle, jet is sprayed along the shower nozzle rear; Four side direction nozzles are installed on the circumferential position at side direction nozzle installing hole place; Make jet along shower nozzle tangential direction ejection, three forward direction nozzles are installed on the position at forward direction nozzle installing hole place, make jet respectively along the axial and oblique ejection of shower nozzle.
The operating principle of the utility model, highly pressurised liquid flows into the one way valve late gate and opens, and gets into shower nozzle through central tube then; Penetrate from each nozzle, the forward direction nozzle forms axial jet and oblique jet again, and axial jet is used to remove the anterior long-pending sand of shower nozzle; Oblique jet is used to remove the long-pending sand on the tube wall of the place ahead in a certain angle with the axis, and the side direction jet penetrates along the tangential direction of shower nozzle; Produce turning pair driving shower nozzle and rotate, the back under the situation of shower nozzle rotation, produces eddy flow field to jet in a segment distance of net horizontal section; So just can make sand and impurity be in suspended state, thus the efficient of the well sand-flushing of improving the standard greatly.Speed limiting mechanism is according to the rotary speed of centrifugal speed limit principle control shower nozzle, and brake pad is divided into four, is installed in the groove on the axle sleeve; It does not directly act on outer tube wall, but be fixed in the mutual friction mutually of urceolus sleeve inside, so both can protect urceolus not to be worn; This sleeve again can secure both ends rolling bearing; The shower nozzle rotating speed is high more, and the centrifugal force of brake pad is just big more, and the frictional force between brake pad and the sleeve is also just big more; Little by little, realize the purpose of control rotary speed with the mutual balance of jet recoil strength.
