Abstract
Disclosed is a tapered stabilizer with a replaceable plate. The stabilizer relates to the field of petroleum. Specifically, the stabilizer is a tapered stabilizer that can replace a wear plate. The stabilizer comprises a body (1). The body (1) is provided with a wear resistant belt (2). The wear resistant belt (2) is provided with an inlay groove (3). The center part of the inlay groove (3) is provided with a convex fixing part (4). The fixing part (4) is provided with a transverse pin hole. A wear resistant block (5) is fixed to the fixing part through the pin hole. The cross section of the wear resistant block (5) is T-shaped. The vertical edge of the wear resistant block (5) is provided with a transverse pin hole. The bottom of the wear resistant block (5) is provided with a longitudinal groove that is snapped into the convex fixing part (4) inside the inlay groove (3) and fixed by a pin. The two ends of the transverse edge of the wear resistant block (5) are provided with inclined surfaces. The two ends of the inlay groove (3) are provided with wedge blocks (6) fixed by screws. The inner side ends of the wedge blocks (6) are abutted against the inclined surfaces of the transverse edges of the wear resistant block (5) through an inclined plane, so as to clamp the wear resistant block (5). The stabilizer improves stability of a drilling well.
Description
Technical field
The utility model relates to petroleum machinery, is specifically related to a kind of tapered stabilizer that can change wear plate.
Background technology
Conventional helical band stabilizer wear-resistant strip and body are monolithic construction, and its diameter dimension can not be changed as required, after wearing and tearing, entirety is scrapped, and have the shortcoming of inadequate economy and durability.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of blades changeable tapered stabilizer is provided.
Technical solution of the present utility model is: it comprises body, body is provided with wear-resistant strip, described wear-resistant strip is provided with embedding groove, in embedding groove, be provided with protruding fixed part in centre position, fixed part is provided with horizontal pin-and-hole, on fixed part, be fixed with wear-resistant block by pin, wear-resistant block cross section is " T " font, its vertical edge is provided with horizontal pin-and-hole, bottom is provided with on the fixed part that longitudinal groove is stuck in embedding groove internal projection and fixes by pin, its horizontal edge is provided with inclined plane in two ends, in embedding groove, be provided with the voussoir fixing by screw in two ends, voussoir medial extremity is against by inclined-plane on the inclined plane of wear-resistant block horizontal edge, wear-resistant block is clamped.
Technique effect of the present utility model is: the stability that has improved drilling well.Owing to having reconfigured direction and the position of wear plate, thereby make the smooth cleannes that improve well of whole righting band.The direction configuration of wear plate has also improved the sliding while making a trip, thereby has reduced the infringement to the borehole wall.Wear plate is easily changed, and stabilizer is safeguarded to more convenient practicality.Size can change by the wear plate of pad or differing heights.Improve wear plate mud flow around.Smooth contact surface reduces friction and vibration.Reduce stock and transport, for those remotenesses, the region that has logistical problems is ideal.Remove the transport that damages stabilizer and need transport to professional shop maintenance from.The ideal product of remote districts.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 1.
Detailed description of the invention
As Fig. 1, shown in 2 and 3, it comprises body 1, body 1 is provided with wear-resistant strip 2, described wear-resistant strip 2 is provided with embedding groove 3, in embedding groove 3, be provided with protruding fixed part 4 in centre position, fixed part 4 is provided with horizontal pin-and-hole, on fixed part 4, be fixed with wear-resistant block 5 by pin, wear-resistant block 5 cross sections are " T " font, its vertical edge is provided with horizontal pin-and-hole, bottom is provided with on the fixed part 4 that longitudinal groove is stuck in embedding groove 3 internal projection and fixes by pin, its horizontal edge is provided with inclined plane in two ends, in embedding groove 3, be provided with the voussoir 6 fixing by screw in two ends, voussoir 6 medial extremitys are against by inclined-plane on the inclined plane of wear-resistant block 5 horizontal edges, wear-resistant block 5 is clamped.
Described wear-resistant strip 2 is at least two sections, and the wear-resistant strip 2 of each section is staggered.
Described embedding groove 3 longitudinal sections are rectangle.
The profile that blades changeable tapered stabilizer strengthens and interchangeable wear plate have improved guidance quality and the stability of stabilizer greatly.For remote or there is no the local operation of infrastructure be ideal instrument, can change fast and easily more wear plate in well site, reduce the cost of stock and transport, this design can be applicable in the stabilizer of all specifications.
Change the monolithic construction of conventional helical band stabilizer wear-resistant strip and body, adopted the fabricated structure of wear plate and body, therefore can change by changing easily the wear plate of differing heights and the pad of different-thickness the diameter dimension of stabilizer.In order to ensure the solid and reliable of combination, adopt voussoir to compress wear plate, the dual fastening means that wear plate is connected with bearing pin with fixed block simultaneously.Two row's interlaced arrangement modes of wear-resistant strips and directions configuration have improved the sliding while making a trip, thereby have reduced the infringement to the borehole wall, thus and the cleannes of well while making that whole righting band is smooth has improved drilling well.Special mud ditch arrangement has improved wear plate mud flow around.
