Description

A kind of coiled tubing wax removal descaling tool
Technical field
This utility model is related to a kind of coiled tubing wax removal descaling tool, belongs to Oil/gas Well downhole tool technical field.
Background technology
In field of oil field oil extraction, horizontal segment sand production in oil phenomenon is increasingly serious, has badly influenced the normal production in oil field. Due to containing waxy substance in the Produced Liquid of oil well, in oil extraction process, waxy substance can combine a large amount of in oil pipe with grit Fouling and wax deposition.In order to ensure the normal operation of Oil/gas Well, current people complete the clear of oil pipe frequently with the mode of sand washing operation Wax scale removal works.Due to the restriction of existing sand flushing device reasons in structure, which has, and sand washing effect is poor, sand washing flows to single, easy product The long-pending sand of tissue regeneration promoting and the problem of effective protection is unable to reservoir, it is impossible to meet the needs of oil field production and application.
The content of the invention
The purpose of this utility model is:A kind of simple structure, easy to use is provided, to solve existing wax removal scale removal mode The sand washing effect that has is poor, sand washing flows to continuous oil that is single, being also easy to produce new long-pending sand and effective protection problem is unable to reservoir Pipe wax removal descaling tool.
The technical solution of the utility model is:
A kind of coiled tubing wax removal descaling tool, it is sprayed by top connection, lower contact, sleeve, rotary sleeve, sleeve nozzle and bottom Mouth is constituted;It is characterized in that:The threaded one end of top connection is connected with lower contact, and bottom nozzle is provided with lower contact;Lower contact with The rotary sleeve arranged by symmetry shape between top connection is provided with sleeve;Injection through hole is evenly equipped with sleeve;The one of injection through hole End is equipped with sleeve nozzle;Annular cavity is provided with the middle part of described sleeve, annular cavity is connected with each injection through hole.
Described sleeve nozzle is 30 ° -60 ° with the angle of axial direction.
In the shape of a spiral, the two ends pore size for spraying through hole differs described injection through hole;The big nose end dress of injection through hole There is sleeve nozzle.
Described top connection is pipe axis body of the profile in multidiameter shape, and pod apertures, described water conservancy diversion are provided with top connection Hole is connected with the annular cavity in sleeve.
Interfixed by holding screw between described lower contact and top connection.
Described lower contact is bullet, and ladder endoporus is provided with lower contact, and the lower end of ladder endoporus is equipped with bottom nozzle.
The utility model has the advantage of:
The coiled tubing wax removal descaling tool, it is simple structure, easy to use, employ uniform spiral on sleeve The structure design of injection through hole, when being worked using the wax removal descaling tool after this kind of design, cleanout fluid can be from injection through hole two ends Spray, flush clean is carried out to oil pipe from upper and lower both direction, the effect of oil pipe paraffin removal scale removal is enhanced.Additionally due to injection is logical Hole is arranged in the shape of a spiral, and when cleanout fluid circulates from injection through hole, cleanout fluid can be rotated with moving sleeve, and then makes cleanout fluid in rotation The state for turning is sprayed from injection through hole, so that oil pipe is uniformly rinsed, it is to avoid rinse the appearance at dead angle.Solve existing Have that the sand washing effect that wax removal scale removal mode has is poor, sand washing flow to it is single, be also easy to produce new long-pending sand and can not be effectively to reservoir The problem of protection, meets the needs of oil field production and application.

In figure:1st, top connection, 2, lower contact, 3, sleeve, 4, rotary sleeve, 5, sleeve nozzle, 6, bottom nozzle, 7, injection it is logical Hole, 8, annular cavity, 9, pod apertures, 10, holding screw.
Specific embodiment
The coiled tubing wax removal descaling tool is sprayed by top connection 1, lower contact 2, sleeve 3, rotary sleeve 4, sleeve nozzle 5 and bottom Mouth 6 is constituted:The threaded one end of top connection 1 is connected with lower contact 2.It is mutual by holding screw 10 between lower contact 2 and top connection 1 It is fixed.Arrange holding screw 10 purpose be:Make lower contact 2 be connected even closer with top connection 1, prevent sending out for case accident It is raw.
Lower contact 2 is bullet, and ladder endoporus is provided with lower contact 2, and the lower end of ladder endoporus is equipped with bottom nozzle 6.Will The endoporus of lower contact 2 is set to step-like purpose:So that cleanout fluid is when the ladder endoporus of lower contact 2, water of compaction Stream, so that bottom nozzle 6 produces bigger injection pressure.
The rotary sleeve 4 arranged by symmetry shape between lower contact 2 and top connection 1 is provided with sleeve 3;Sleeve 3 and rotary sleeve 4 Between installed by the way of interference fit;Pacified by the way of the cooperation of gap between rotary sleeve 4 and top connection 1 Dress;The purpose being arranged such is:The frictional resistance between rotary sleeve 4 and top connection 1 is reduced, facilitates the rotation of sleeve 3.
Injection through hole 7 is evenly equipped with sleeve 3;Injection through hole 7 is in the shape of a spiral.Injection through hole 7 is arranged into spiral mesh Be:So that cleanout fluid is from impingement sleeve 3 when through hole 7 circulates is sprayed, so that sleeve 3 produces rotation.
The two ends pore size of injection through hole 7 differs;The big nose end of injection through hole 7 is equipped with sleeve nozzle 5.Sleeve nozzle 5 Multiple spray orifices are provided with inside;Described spray orifice in the injection consistent helical form of through hole 7, the purpose being arranged such is:So that clear When washing liquid flows through spray orifice so as to produce radial impact force, the further rotating speed for improving sleeve 3.
Sleeve nozzle 5 is 30 °~60 ° with the angle of axial direction, by the purpose that sleeve nozzle 5 is arranged such is:With Make cleanout fluid from sleeve nozzle 5 spray when, be ejected on coiled tubing at an angle, to the waxy substance on coiled tubing and Dirt is cleared up.
Annular cavity 8 is provided with the middle part of sleeve 3, annular cavity 8 is connected with each injection through hole 7.Top connection 1 for profile is in The pipe axis body of multidiameter shape, is provided with pod apertures 9 in top connection 1, pod apertures 9 are connected with the annular cavity 8 in sleeve 3.
When the coiled tubing wax removal descaling tool works, under the cooperation of extraneous aid, a part of cleanout fluid can edge Top connection 1 to be passed through in the ladder endoporus of lower contact 2, and it is spouting eventually through bottom nozzle 6, to the waxiness on coiled tubing Thing and dirt are cleared up.The cleanout fluid of another part can pass through pod apertures 9 and annular cavity 8 is flowed in injection through hole 7, stream Enter to spray the cleanout fluid part in through hole 7 to be sprayed by portlet upwards, another part can be sprayed by sleeve nozzle 5 downwards Go out.Thus cleanout fluid can carry out flush clean to oil pipe from upper and lower both direction.
In the above process due to spray through hole 7 arrange in the shape of a spiral, cleanout fluid from injection flow therethrough when can drive set Cylinder 3 is rotated.Sleeve 3 sprays can from 7 two ends of injection through hole state of the cleanout fluid in rotation for ejecting in rotation process, Oil pipe is uniformly rinsed, so as to avoid the appearance for rinsing dead angle.
The coiled tubing wax removal descaling tool, it is simple structure, easy to use, solve what existing wax removal scale removal mode had Sand washing effect is poor, sand washing flows to problem that is single, being also easy to produce new long-pending sand and effectively can not protect to reservoir, meets oil field The needs of production and application.
