The utility model discloses a device, rotation rate through speed reducer structure has reduced the instrument has strengthened washing effect.
Description
Technical field
The utility model belongs to mechanical equipment technical field, relates to a kind of coiled tubing spin rinse instrument.
Background technology
Coiled tubing has the little advantage of external diameter, can enter the casing deformation well section that plain tubing can not arrive down.Use rotary nozzle to carry out clean-out service, have the following disadvantages: utilize the jet flow reacting force of highly pressurised liquid to promote shower nozzle and rotate, along with the increase of fluid pressure, the rotary speed of shower nozzle will quickly, easily cause spraying fluid and be sharply atomized, reduce cleaning performance; And high rotating speed can make rotary part sharply wear and tear, reduce application life.
Owing to there is above problem, need the spin rinse instrument with deceleration.
Utility model content
The purpose of this utility model is to provide a kind of coiled tubing spin rinse instrument, solve prior art spin rinse instrument and do not have deceleration, along with the increase of fluid pressure, the rotary speed of shower nozzle will quickly, easily cause spraying fluid to be sharply atomized, reduce cleaning performance; And high rotating speed can make rotary part sharply wear and tear, reduce the problem in application life.
The technical solution adopted in the utility model is, a kind of coiled tubing spin rinse instrument, comprises top connection, and top connection one end is connected with continuous-tube by PAC button, the top connection other end and sleeve connection;
Jointly be set with mandrel in top connection and sleeve lining respectively by an axle sleeve, mandrel cylindrical is provided with two shaft shoulders, the outside of two shaft shoulders is respectively arranged with a packing ring, is provided with bearing between each packing ring and corresponding axle sleeve; The mandrel one end of stretching out from sleeve is connected with shower nozzle.
Coiled tubing spin rinse instrument of the present utility model, is further characterized in that:
The outer ring of bearing is close to packing ring, and the inner ring of bearing is close to axle sleeve, and the inner ring of bearing and mandrel are matched in clearance.
The shaft shoulder of mandrel is provided with oil storage tank.
The sealing of O type circle is provided with between top connection and mandrel, between sleeve and mandrel, between top connection and sleeve.
The beneficial effects of the utility model are, the structure of this deceleration device is simple, and reliable operation, reduces the rotary speed of instrument, enhance developing result, obviously shorten construction period, reduce labour intensity.
Accompanying drawing explanation
Fig. 1 is the half sectional view of the utility model coiled tubing spin rinse instrument;
Fig. 2 is the A-A schematic cross-section of Fig. 1.
In figure, 1. top connection, 2. axle sleeve, 3. sleeve, 4. packing ring, 5. bearing, 6. mandrel, 7. shower nozzle.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, Fig. 2, structure of the present utility model is, comprises top connection 1, and top connection 1 one end is connected with continuous-tube by PAC button, and top connection 1 other end is connected with sleeve 3 by screw thread, and fixes the relative position of top connection 1 and sleeve 3 by holding screw;
Mandrel 6 is jointly set with respectively by an axle sleeve 2 in top connection 1 and sleeve 3 inwall, mandrel 6 cylindrical is provided with two shaft shoulders, these two shaft shoulders are arranged in top connection 1 and sleeve 3 inner chamber, the outside of two shaft shoulders is respectively arranged with a packing ring 4, bearing 5 is provided with between each packing ring 4 and corresponding axle sleeve 2, the outer ring of bearing 5 is close to packing ring 4, and the inner ring of bearing 5 is close to axle sleeve 2
The shaft shoulder of mandrel 6 is provided with oil storage tank, for storing damping grease, a large amount of damping grease is full of bearing place annular space (i.e. top connection 1 and sleeve 3 inner chamber in), and damping grease is a kind of high-drag lubricating grease, play the retardance to bearing rotary and buffering, thus reduce shower nozzle 6 rotating speed.The diagonal angle of axle sleeve 2 and packing ring 4 shape matched bearings 5 is fixed, inner ring and the mandrel 6 of bearing 5 are matched in clearance, washer 4 is with to rotate together with bearing 5 outer ring when mandrel 6 rotates, bearing 5 inner ring does not rotate, this locate mode of bearing 5 is conducive to the contact area increasing damping grease and bearing 5 outer ring, thus strengthens the decelerating effect to bearing 5.With the sealing of O type circle between top connection 1 and mandrel 6, between sleeve 3 and mandrel 6, between top connection 1 and sleeve 3, bearing 5 is in a complete hermetic cavity, makes bearing 6 not by the pollution of cleaning fluid, and make damping grease leak out bearing bore;
Mandrel 6 one end of stretching out from sleeve 3 is connected by screw thread with shower nozzle 7, adopts holding screw to fix between shower nozzle 7 and mandrel 6, does not throw off when shower nozzle 7 is rotated with mandrel 6.
With reference to Fig. 2, radially uniform 3 spouts of shower nozzle 7, when high-pressure cleaning liquid is along the tangential direction ejection of shower nozzle 7, the reaction force of flushing liquor, to shower nozzle 7 one moments of torsion, makes shower nozzle 7 be with moving mandrel 6 to rotate together.High pressure liquid stream, by the shower nozzle 7 be rotating, is directed to the borehole wall by flushing liquor, effectively can remove unconsolidated dirt, sand and chip on the borehole wall, reduces the oil pipe resistance of going into the well and in trip-out process.
During onsite application, the top connection 1 of this rotary nozzle is connected by connector with coiled tubing, by arriving the position needing to rinse under spin rinse instrument, opens pump truck or flushing liquor valve, can implement to rinse.
