Abstract
The utility model discloses an oil well cement slurry settling pipe jacking pipe, which comprises a regular hexagonal cover body, wherein a cylindrical clamping groove is axially and upwards formed in the center of the bottom surface of the regular hexagonal cover body, and the inner diameter of the cylindrical clamping groove is matched with the outer diameter of a pipe body of the oil well cement slurry settling pipe, so that the pipe body can be tightly buckled in the cylindrical clamping groove; a first overflow groove, a second overflow groove and a third overflow groove are respectively and crossly formed in the groove bottom of the cylindrical clamping groove, and each overflow groove penetrates through one group of opposite side walls of the cover body; this oil well grout subsides pipe top tube simple structure, reasonable in design, convenient operation, its regular hexagonal body structure can realize convenient and fast's fixed and dismantle the top cap, and through opening at the inboard equipartition of lid and set up three and flow over the grout that the groove realized in the unnecessary sedimentation tube of in time discharging, improves experimental efficiency.
Description
Technical Field
The utility model relates to an oil well grout detection device technical field, in particular to oil well grout settling leg top cap.
Background
The oil well cement slurry stability is one of the most frequently tested parameters of the oilfield chemical fluid, which directly influences the quality of well cementation, and the settling pipe of the oil well cement slurry is the most frequently used instrument for measuring the slurry stability of the cement slurry.
The present used cement paste sedimentation pipe top cap outward appearance is the cylinder, has the cylinder sedimentation pipe draw-in groove of recessed in, has a recess in the draw-in groove to be used for discharging unnecessary cement paste. But discovery current grout settling leg top cap has cylinder top cap to dismantle inconvenient problem during the experiment, still has the unable in time discharge of jar body unnecessary grout in addition, leads to the problem that influences experimental result and experimental efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a convenient and fast's fixed and dismantle the oil well grout settling leg top cap of top cap and can in time discharge grout.
Therefore, the utility model discloses technical scheme as follows:
the top cover of the oil well cement slurry settling pipe comprises a cover body, wherein the cover body is a regular hexagonal body, a cylindrical clamping groove is formed in the center of the bottom surface of the cover body in the upward direction along the axial direction, and the inner diameter of the cylindrical clamping groove is matched with the outer diameter of a pipe body of the oil well cement slurry settling pipe, so that the pipe body can be tightly buckled in the cylindrical clamping groove; the bottom of the cylindrical clamping groove is respectively and crossly provided with a first overflow groove, a second overflow groove and a third overflow groove, and each overflow groove is communicated with a group of opposite side walls of the cover body.
Furthermore, a first overflowing groove formed in the bottom of the cylindrical clamping groove penetrates through the middle of the first group of opposite side walls of the cover body, a second overflowing groove formed in the bottom of the cylindrical clamping groove penetrates through the middle of the second group of opposite side walls of the cover body, and a third overflowing groove formed in the bottom of the cylindrical clamping groove penetrates through the middle of the third group of opposite side walls of the cover body, so that an included angle formed between every two adjacent overflowing grooves is 60 degrees.
Further, the width of the first overflow groove, the second overflow groove and the third overflow groove is 2-3 mm.
Compared with the prior art, this oil well cement slurry sedimentation pipe roof tubular construction is simple, reasonable in design, convenient operation, and convenient and fast's fixed and dismantlement top cap can be realized to its regular hexagonal body structure, and opens through the inboard equipartition of lid and sets up three and flow through the groove and realize the cement slurry in the unnecessary sedimentation pipe of in time discharging, improves experimental efficiency.
Drawings
FIG. 1 is a schematic structural view of a top cover of the oil well cement slurry settling pipe of the present invention;
fig. 2 is a sectional view a-a of fig. 1.
Detailed Description
The present invention will be further described with reference to the following drawings and specific examples, but the following examples are by no means limiting the present invention.
As shown in fig. 1, the top cover of the oil well cement slurry settling pipe is a cover body 1 with a regular hexagonal structure, and compared with a cylinder which is commonly used at present, the top cover can be conveniently and quickly fixed and detached;
as shown in fig. 2, a cylindrical clamping groove 2 is axially and upwardly formed in the center of the bottom surface of the cover body 1, and the inner diameter of the cylindrical clamping groove 2 is adapted to the outer diameter of the pipe body of the oil well cement slurry settling pipe, so that the pipe body can be tightly buckled in the cylindrical clamping groove 2;
for realizing removing the function of surplus cement thick liquid, first overflow groove 3a has been seted up in the tank bottom of cylindrical draw-in groove 2 alternately respectively, second overflow groove 3b and third overflow groove 3c, specifically, set up in the first overflow groove 3a of 2 tank bottoms of cylindrical draw-in groove and run through the first group contralateral wall middle part of lid 1, set up in the second overflow groove 3b of 2 tank bottoms of cylindrical draw-in groove and run through the second group contralateral wall middle part of lid 1, set up in the third overflow groove 3c of 2 tank bottoms of cylindrical draw-in groove and run through the third group contralateral wall middle part of lid 1, make the contained angle that forms between every two adjacent overflow grooves be 60. In addition, the first overflow groove 3a, the second overflow groove 3b, and the third overflow groove 3c are all 3mm in width to discharge excess cement slurry to the outside in time.
The above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the technical solution of the present invention, and the protection scope of the present invention is not limited thereto, although the present invention is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: those skilled in the art can still modify or easily conceive of changes in the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features within the technical scope of the present disclosure; such modifications, changes or substitutions do not substantially depart from the spirit and scope of the embodiments of the present invention, and are intended to be included within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
