Skill.
Summary of the invention
Size mud cake removal device is crossed technical problem to be solved by the invention is to provide a kind of, simplifies technique, extends and use
Service life, to solve the above-mentioned many defects caused by the prior art.
To achieve the above object, the present invention provides technical solution below: a kind of to cross size mud cake removal device, including righting
Device, the centralizer both ends are equipped with multiple wiper blocks in outer side wall, wiper block spaced set, the wiper block at centralizer both ends it
Between be equipped with steel tendon.
Preferably, the wiper block at the steel tendon both ends is staggered so that steel tendon uniform eddy flow distribution, between there are
Swirl channel.
A kind of production technology for crossing size mud cake removal device, by centralizer, centralizer and steel tendon separate machined, then carries out
Assembling；Steps are as follows,
1) centralizer uses 45#Steel seamless steel tube；
2) wiper block uses 45#Steel quenches modifier treatment；
3) steel tendon is using quenched middle high-amplitude wave line braided steel wire at cord beam；
4) centralizer and wiper block welding fabrication, fixation hole is equipped at wiper block, and steel tendon is planted in fixation hole.
Preferably, in the step 2), the derusting of wiper block surface sand-blasting carries out spiral shell Milling Machining.
Preferably, steel wire uses 75 manganese steel silk of high-strength elastic, is quenched, steel wire ripple forming is woven into finer wire
Rope.
Preferably, surface plastic spraying is handled, using electrostatic powder plastic-spraying on the surface of component.
Be using the beneficial effect of above technical scheme: the structural strength of structure of the invention is high, and intensity of steel wire is moderate, elastic
The features such as high, antifatigue and good toughness, overall surface smooth pieces, antirust ability is strong.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Wherein, 1-- centralizer, 2-- wiper block, 3-- steel tendon.
Specific embodiment
The preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings.
Fig. 1 shows a specific embodiment of the invention: a kind of to cross size mud cake removal device, including centralizer, the righting
Device both ends are equipped with multiple wiper blocks in outer side wall, and wiper block spaced set is equipped with steel wire between the wiper block at centralizer both ends
Beam；The wiper block at the steel tendon both ends is staggered so that steel tendon uniform eddy flow distribution, between there are swirl channels.
A kind of production technology for crossing size mud cake removal device, by centralizer, centralizer and steel tendon separate machined, then carries out
Assembling；Steps are as follows,
1) centralizer uses 45#Steel seamless steel tube；
2) wiper block uses 45#Steel quenches modifier treatment, and the derusting of wiper block surface sand-blasting carries out spiral shell Milling Machining；
3) using quenched middle high-amplitude wave line braided steel wire at cord beam, steel wire uses 75 manganese steel silk of high-strength elastic, does steel tendon
Quenching treatment, steel wire ripple forming are woven into seizing wire；
4) centralizer and wiper block welding fabrication, are equipped with fixation hole at wiper block, and steel tendon plants the surface spray in fixation hole
Modeling processing, using electrostatic powder plastic-spraying on the surface of component.
Entirety is according to rigid centralizer specification.Righting strip is changed to both ends wiper block, process wire beam.Both ends wiper block is made
For supporter, it can satisfy righting, shock resistance and the needs for protecting steel tendon；Steel tendon uses quenched middle high-amplitude wave line braided steel wire
At cord beam, steel body is coupled with rope beam using non-solder mode, further enhances antifatigue damage capability.According to different well type
It can choose the steel wire type of varying strength and length.Overall arc-shaped design, length (outer diameter) is according to hole enlargement ratio 2-
15%, brush, cleaning borehole wall ability are hung in enhancing.
Steel body: using 45# steel seamless steel tube, and wiper block uses 45#Steel quench modifier treatment, steel body, wiper block have compared with
High yield strength, impact resistance are strong；Steel wire: using 75 manganese steel silk of high-strength elastic, phosphate coat, and rope making can be improved in phosphating coat
Wear-resistant, the corrosion resistance of steel wire surface.Steel wire ripple forming is woven into seizing wire, toughness with higher and bullet modeling
Property, antifatigue damage capability is strong.Achieve the purpose that realize under the premise of not destroying wellbore stability and removes annular space wall cake.
Using rigid centralizer specification, steel body one-pass molding, guarantee has enough intensity, and shock resistance is tamper-proof；Steel tendon
Five uniform eddy flows distributions, between there are swirl channel, hanging the false filter cake brushed off or landwaste can pass through.Steel tendon endurance foot
When enough big, there can be extending space, while having the effect of buffering and caching to big barrier, be unlikely to block drilling rod；
Steel tendon is planted in steel tendon fixation hole, and steel tendon fixation hole opening direction is inlayed non-solder, kept away perpendicular to the center of circle, ripple steel wire
Exempt from fatigue rupture of the solder joint under external force, it is firm and durable.
Mud cake removal device is placed in the lower part of casing string, casing string during entering well because steel wire outer diameter is according to well
Diameter amplification degree 2-15% design carries out physical removal to the false filter cake on the borehole wall.It can be according to down-hole formation or Open-Hole Section stratum
Lithology and well track selection place quantity, create conditions for cement with formation cementation, to improve second interface cementing quality.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention
Protection scope.
