Description
Technical field
The present invention relates to the down-hole cement plugging device of a kind of oil, geological drilling well cementation, be specifically related to a kind of Novel cementing basket.
Background technology
The domestic capping tools great majority preventing cement paste in Process of Cementing from sinking used in oil, geological drilling engineering adopt basket, leather cup, external casing packer at present, owing to there is the danger that umbrella is worn in going into the well process at basket with wall friction, simultaneously, can especially open completely at horizontal well horizontal segment after basket puts in place, support live in portion's cement sheath, it need further textual criticism; Leather cup is the normal partition mode adopted, and the outside dimension of leather cup, close to borehole size, enters difficulty under often there is pipe string, leak the risk on stratum simultaneously with pressure in the construction of horizontal well especially sidetracked hole; Can packer be directly used in job site, for irregular borehole or there is the abdominous well section in down-hole, reach actual partition effect, support lives in portion's cement etc. and all also have problems.
Summary of the invention
The invention is intended to provide a kind of Novel cementing basket, to solve the deficiencies in the prior art, the technical problem to be solved in the present invention is achieved through the following technical solutions.
A kind of Novel cementing basket, it comprises centralizer body, body resistance-strengthening tablets, righting face, rivet, alignment pin;
Described centralizer body comprises circle body and lower circle body, described upper and lower circle body is circle and is spliced by two semicircular circle bodies, each semicircular circle body is provided with locating hole, two semicircular circle bodies are connected through locating hole by alignment pin, thus the circle body that formation one is complete;
Described locating hole is blind hole, and the degree of depth of described blind hole is more than or equal to the length of alignment pin, is interference fit between alignment pin and locating hole;
Described body resistance-strengthening tablets is the circular arc of 120 °, central angle, radius 5-15cm, and its thickness is 2-4mm, width is 5-10mm; Described body resistance-strengthening tablets employing has flexible steel disc and makes, and its quantity is 8-16 sheet, is uniformly distributed along upper and lower circle body circumference, and is fixed on upper and lower circle body by the mode of welding or riveting;
Described righting face covers on body resistance-strengthening tablets, and be connected with body resistance-strengthening tablets in body resistance-strengthening tablets maximum diameter place by rivet, the quantity in described righting face is identical with the quantity of body resistance-strengthening tablets, and its width is greater than the width of body resistance-strengthening tablets, and the two ends, righting face exceeding body resistance-strengthening tablets width are stuck up respectively to indent.
Further, described body resistance-strengthening tablets is 12; Described righting face is sheet rubber, and its thickness is 3-5mm.
Further, described body resistance-strengthening tablets is 8; Described righting face is spring leaf, and its thickness is 1.5-3mm.
Further, described body resistance-strengthening tablets is 16, and described righting face is canvas strips, and its thickness is 2mm.
The present invention has structure advantage that is simple, easy for installation, not cracky, has the effect of centralizer simultaneously.Because body resistance-strengthening tablets has certain flexibility and intensity, basket can be solved well and to go into the well the problem being worn in process to sink with cement paste, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Reference numeral in accompanying drawing is followed successively by: 1, upper circle body, and 2, lower circle body, 3, body resistance-strengthening tablets, 4, righting face, 5, alignment pin, 6, locating hole, 7, rivet.
Detailed description of the invention
Design feature of the present invention is set forth further below in conjunction with accompanying drawing and specific embodiment.
A kind of Novel cementing basket, it comprises centralizer body, body resistance-strengthening tablets 3, righting face 4, rivet 7, alignment pin 5; Described centralizer body comprises circle body 1 and lower circle body 2, described upper and lower circle body is circle and is spliced by two semicircular circle bodies, each semicircular circle body is provided with locating hole 6, two semicircular circle bodies are connected through locating hole by alignment pin, thus the circle body that formation one is complete; Described locating hole is blind hole, and the degree of depth of described blind hole is more than or equal to the length of alignment pin, is interference fit between alignment pin and locating hole; Described body resistance-strengthening tablets is the circular arc of 120 °, central angle, radius 5-15cm, and its thickness is 2-4mm, width is 5-10mm; Described body resistance-strengthening tablets employing has flexible steel disc and makes, and its quantity is 8-16 sheet, is uniformly distributed along upper and lower circle body circumference, and is fixed on upper and lower circle body by the mode of welding or riveting; Described righting face covers on body resistance-strengthening tablets, and be connected with body resistance-strengthening tablets in body resistance-strengthening tablets maximum diameter place by rivet, the quantity in described righting face is identical with the quantity of body resistance-strengthening tablets, and its width is greater than the width of body resistance-strengthening tablets, and the two ends, righting face exceeding body resistance-strengthening tablets width are stuck up respectively to indent.
See Fig. 1, the body resistance-strengthening tablets in the present embodiment is 8; Described righting face is spring leaf, and its thickness is 1.5-3mm.
The present invention has structure advantage that is simple, easy for installation, not cracky, has the effect of centralizer simultaneously.Because body resistance-strengthening tablets has certain flexibility and intensity, basket can be solved well and to go into the well the problem being worn in process to sink with cement paste, safe and reliable.
The above embodiment only have expressed one embodiment of the present invention, but therefore can not be interpreted as limitation of the scope of the invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, some distortion and improvement can also be made.These all belong to protection scope of the present invention.
