Abstract
The invention discloses a kind of oil pumping pipeline rotary centralizers, are related to oil pipe field of components.Including pipeline ontology and centering ring, centering ring is flexibly connected with pipeline ontology, and centering ring inner wall is equipped with ring-shaped guide rail, and carriage is arranged in the position opposite with ring-shaped guide rail on pipeline body outer wall, and carriage is run along ring-shaped guide rail；It is spaced a distance between each ring-shaped guide rail, the parallel uniform intervals setting of multiple ring-shaped guide rails；Bending camber extension section in centering ring both ends, arc extension section are flexibly connected and close with the outer wall of pipeline ontology, form closed cavity between centering ring and pipeline ontology at this time；The arc extension section is flushed with the part of pipeline body contacts with the outer surface of pipeline ontology, and is provided with sealing ring between the part and pipeline ontology.The centralizer structure is simple, and can be played under various operating modes and rotate unobstructed effect, can ensure that construction operation is normally carried out.
Description
Technical field
The present invention relates to oil pipe field of components, especially a kind of setting and the rotary centralizer in oil pick-up tube.
Background technology
Directed drilling and Sidetracking Technology in the prior art have a wide range of applications.Downhole tool tubing string is complete in horizontal well
Prodigious friction resistance must can be encountered when tool enters horizontal bare hole well section by the flex socket of angle buildup interval when well operations
Power, may have accumulated within reservoir sand and rock fragment in wellbore will be such that tubing string tripping in resistance further increases, when resistance is excessive, pipe
Column tripping in operation will be forced to stop, it usually needs playing tubing string and out carry out drifting operation, or shorten completion length, in advance
Terminate construction operation, unnecessary loss is brought to horizontal well oil and gas development.
Invention content
The goal of the invention of the present invention is：In view of the above problems, a kind of oil pumping pipeline rotary centralizer is provided, it should
Centralizer structure is simple, and can be played under various operating modes and rotate unobstructed effect, can ensure that construction operation is normally carried out.
The technical solution adopted by the present invention is as follows：
A kind of oil pumping pipeline rotary centralizer, including pipeline ontology and the centering ring that is socketed on pipeline ontology, the righting
Ring is flexibly connected with pipeline ontology, offers ring-shaped guide rail on the centering ring inner wall, on the pipeline body outer wall with annular
The opposite position of guide rail is provided with carriage, and carriage is detachably connected with pipeline ontology, and carriage is led along annular
Rail is run.
Further, the ring-shaped guide rail is multiple, and spaced a distance, multiple annulars between each ring-shaped guide rail
The parallel uniform intervals setting of guide rail.
Further, bending camber extension section in the centering ring both ends, arc extension section are outer with pipeline ontology
Wall is flexibly connected and closes, and forms closed cavity between centering ring and pipeline ontology at this time.
Further, the arc extension section is flushed with the part of pipeline body contacts with the outer surface of pipeline ontology, and
It is provided with sealing ring between the part and pipeline ontology.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
The centralizer of the present invention will be by that will be sleeved on pipeline ontology outside centering ring and can rotate on it, and by centering ring
The segmental arc that both ends setting is extended makes by the mating setting of carriage and ring-shaped guide rail between pipeline ontology and centering ring
Obtaining centering ring can rotate freely on pipeline ontology, and the setting of multiple ring-shaped guide rails and carriage so that it is rotated more
To be unimpeded, closed cavity is formed between centering ring and pipeline ontology, even if some is damaged between carriage and ring-shaped guide rail
It is bad etc., nor affect on its whole normal operation.The setting of sealing ring is even more that ensure that channel interior carriage is led with annular
Rail is not influenced by external asphalt channel.
Description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is structure of the invention and principle schematic.
Wherein reference numeral：1 be pipeline ontology 2 be centering ring 3 is ring-shaped guide rail
4 be carriage 5 be arc extension section 6 be sealing ring.
Specific implementation mode
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
This specification（Including any accessory claim, abstract）Disclosed in any feature, unless specifically stated,
It is replaced by other equivalent or with similar purpose alternative features.That is, unless specifically stated, each feature is a series of
An example in equivalent or similar characteristics.
A kind of oil pumping pipeline rotary centralizer of the invention as shown in Fig. 1, including pipeline ontology and it is socketed in pipeline
Centering ring on ontology, the centering ring are flexibly connected with pipeline ontology, we are by bending inwards centering ring both ends shape
Camber section, and segmental arc is parallel with the surface of pipeline ontology with after the bending of part that pipeline ontology connects, segmental arc it is whole with
Pipeline ontology is flexibly connected, and can be sealed by sealing device, makes to form sealing sky between centering ring and pipeline ontology
Chamber, carriage run in the sealing cavity with ring-shaped guide rail, are not interfered by extraneous oil circuit, ring-shaped guide rail setting how righting
On ring inner wall, opposite with ring-shaped guide rail position on pipeline body outer wall, carriage and pipeline is arranged in the carriage
Ontology is detachably connected, and carriage is run along ring-shaped guide rail.
In addition, in order to make external oil circuit not enter in closed cavity, between carriage and ring-shaped guide rail
Cooperation impacts, or corrodes its internal structure, we are provided with close at the position of arc extension section and pipeline body contacts
Seal, generally can be on pipeline ontology and sealing ring is respectively set in arc extension section and coordinates with the sealing ring groove knot
Multi-level groove and ring structure can be arranged in structure, ensure sealing and the relative rotation between centering ring and pipeline ontology
Movement.
The invention is not limited in specific implementation modes above-mentioned.The present invention, which expands to, any in the present specification to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.
