Abstract
The invention provides an anti-abrasion device for a drill pipe and a casing pipe. The anti-abrasion device consists of a metal frame, a rubber sleeve and a locking block. Both sides of two semi-cylinder metal frames are correspondingly provided with a dovetail slide groove and a slide bar capable of axially sliding for fastening together respectively. A plurality of oblong holes are formed at the periphery of the metal frame. Two small dovetail slots are formed in the fastening gap respectively. Two semi-cylinder rubber sleeves are correspondingly arranged in the metal frame. A plurality of oblong fillets corresponding to the oblong holes on the metal frame are arranged outside the circumference of the rubber sleeve. The top of the oblong fillets extends out of the external surface of the metal frame and the external surface of the drill pipe joint. An arc rectangular locking block with slopes at both sides is arranged in the small dovetail slots at both sides of the metal frame.
Description
Technical field:
The present invention relates to oil, geological drilling field, relate in particular to a kind of drilling well drilling rod, sleeve pipe abrasionproof device.
Background technology:
The appearance of extended reach well has had history for many years, mainly for economically consideration, has particularly brought into play huge economic benefit in the application of Hai Youlu aspect adopting.But, big displacement extended reach well has very long big gradient steady tilted section, has very large horizontal movement, measures the degree of depth that well bore has reached deep-well, ultradeep well, it is the comprehensive embodiment of directional well, horizontal well, ultradeep well drilling technology, is state-of-the-art in the world at present drilling technology.
In horizontal well, extended reach well and super dark straight well drilling process, the wearing and tearing of drilling rod, sleeve pipe are very serious problems, and are often worn out the sleeve pipe in early stage, cause the destruction of casing programme even scrap, and the tool joint serious wear causes scrapping in advance of drilling tool.Thus, developed the sleeve pipe abrasionproof device of a lot of types both at home and abroad.Mainly contain two types, a kind of is the abrasionproof device that is enclosed within on the drilling rod, and another kind is " blast joint " that is connected between drilling rod and the drilling rod.But generally all exist the unreasonable structure problem.Because two ends of drill all has larger-diameter joint, the abrasionproof device that is enclosed within on the drilling rod does not just fundamentally solve the safety issue of self, mainly is not break through on the structure.Therefore the people is arranged with regard to the design studies blast joint.Blast joint also exists several big problems, first on structure, be exactly that a not rotary sleeve is arranged on the pipe nipple, the not only not sealing that has, but also there are not rolling bearing, surface not to have anti-wear material yet, in subsurface environment, the grains of sand enter in the gap of this " not rotary sleeve ", should " not rotary sleeve " have what the probability that do not rotate to be worth inquiring into; In the process that makes a trip sleeve pipe also there are certain wearing and tearing.Second has increased the joint of many screwed connections in drill string, increased more unsafe factor and danger.The 3rd these blast joint surfaces all are metal shells, when drilling tool produces when radially shaking with the sleeve pipe collision, knocks, also can cause sleeve pipe, drilling rod to thread off, be out of shape problems such as cement sheath destruction.
In addition, because extended reach well, horizontal well have big gradient, long bore hole steady tilted section, so in drillng operation, because of the gravitational effect drill string is subjected to bigger frictional resistance and moment of torsion, moment of torsion, high frictional resistance and high moment of torsion become the key factor of restriction extended reach well extended distance.
Therefore, the research performance abrasionproof device that is enclosed within on the drilling rod good, good reliability is the problem that affiliated technical field is inquired into always.
Summary of the invention:
Purpose of the present invention is intended to overcome the deficiencies in the prior art part; provide a kind of frictional resistance and moment of torsion that can reduce drilling tool, and the drilling rod, the sleeve pipe abrasionproof device purpose of the present invention that have good damping and protective effect when drilling tool radially shakes can realize by following technical measures:
This abrasionproof device is that the novel drill string that is enclosed within on the drilling rod protects hoop, by metallic framework, rubber sleeve and lock dog constitute, two the corresponding respectively dovetail chute and draw runners that can axially slip into fastening that are provided with in both sides that are semicylindrical metallic framework, can snap together to slipping into from different two ends aiming axis, form a cylindric skeleton, the circumference of metallic framework has many Long Circle holes, fasten the place, slit two little swallow tail draw-in grooves are arranged respectively, there are corresponding two of being provided with to be semicylindrical rubber sleeve in the metallic framework, the circumference of rubber sleeve has stupefied of many Long Circles corresponding with the Long Circle hole on the metallic framework outward, stupefied shape and distribution are corresponding with the Long Circle hole on the metallic framework, the end face that Long Circle is stupefied exceeds metallic framework external surface and tool joint external surface, both sides sloping arc cuboid lock dog is installed in the little swallow tail draw-in groove on metallic framework both sides, prevents two metallic framework axial slips.
Purpose of the present invention also can realize by following technical measures:
Stupefied of described Long Circle has the 4-7 bar.
High-strength alloy steel frame of the present invention is made up of two semicircular cylinders, dovetail groove is being with on both sides respectively, the centre mills out many Long Circle holes respectively, the abrasionproof rubber sleeve also is made up of two semicircle tubes, tube outer surface protrudes stupefied of many Long Circles respectively, corresponding with the Long Circle hole of high-strength alloy steel frame respectively, embed in two semicircular cylinder high-strength alloy steel frames, stupefied end face of Long Circle exceeds high-strength alloy steel frame external surface and tool joint external surface.The high-strength alloy steel frame that elder generation the abrasionproof rubber sleeve to half embedding on the drilling rod that needs are installed is stuck on the drilling rod, the high-strength alloy steel frame that the abrasionproof rubber sleeve in second half embedding axially pushes by dovetail groove then, in conjunction with being installed together, in the middle of two high-strength alloy steel frame connecting portions, lock at last, prevent to move axially mutually and break away from two lock dogs.Like this, what contact with drilling rod is the abrasionproof rubber sleeve, what contact with well inner sleeve inwall also is rubber sleeve (stupefied position), under the drilling fluid environment, the friction factor of rubber and metal is very little, so just in the rotary drilling process and the process that makes a trip, avoided the mutual wearing and tearing of tool joint and sleeve pipe well, and reduced the frictional resistance and the moment of torsion of drilling tool effectively.High strength alloy steel metallic framework of the present invention and rubber wearing bush securely " cover " on drilling rod; can on drilling rod, rotate, move up and down; under the drilling fluid environment; rubber and metal have very low friction factor; drilling rod rotates in portion's rubber shaft bearing within it; reduced the drilling tool moment of torsion effectively, solved the big problem of frictional resistance moment of torsion in casing wear problem and horizontal well, the extended reach well casing section well, and when drilling tool radially shakes, had good damping and protective effect.Simple in structure, safe and reliable, conveniently assemble and disassemble, reusable, be a kind of simple, practical drilling tool.
