Abstract
A kind of geological resource reconnoitres well casing ball-type rigidity erection device, and the down-hole casing righting after drilling well barefoot completion is equipped between two parties.There is the supporting rib boss (2) in four roads sleeve pipe ball-type rigidity erection device body (1) outside, be greater than processing in the supporting rib boss (2) of casing coupling external profile diameter and body (1) tube wall at its diameter to be provided with ball sleeve (5) inside ball (3) is installed, contact supporting sleeve righting with sleeve pipe (7) and open hole well barrel (8) respectively at body (1) inside and outside four direction placed in the middle; Be through with cement paste lubrication duct (4) at supporting rib boss (2) and the upper and lower of ball sleeve (5), ensure the rolling lubrication of ball (3) by cement paste effect.In well drilling well completion casing process, sleeve pipe ball-type rigidity erection device body (1) is sleeved on connects on the sleeve pipe of going into the well, and realizes the righting in open hole well barrel (8) of lower casing and cements the well between two parties, effectively solve casing eccentricity problem.
Description
Technical field
The utility model relates to a kind of geological resource and reconnoitres well casing ball-type rigidity erection device, and the down-hole casing righting especially after drilling well barefoot completion is equipped between two parties.
Background technology
At present, in the resource exploration drilling process of geological drilling stratum, rod bit rubs on the stratum different from geological structure lithology soft durometer and amplitude fluctuation is crept into, form the rough borehole wall of uncased wellbore and certainly have the irregular barefoot intervals such as part elliptical, completion needs at stratum uncased wellbore and sleeve pipe outer ring space well cementing of cement, ensure that sleeve pipe is stablized, now use traditional spring leaf erection device cannot support sleeve pipe tubing string supporting positive cover pipe completely and there is eccentricity issues between two parties, that the sleeve pipe that causes that cannot predict does not have righting just to cement the well between two parties the eccentric phenomena caused at irregular barefoot interval on ground, make follow-up production operation in sleeve pipe, downhole tool and tubing string external surface and internal surface of casing are in the mutual serious wear in partial eccentricity position, casing wear is caused and thinningly affects sleeve pipe and downhole tool and tubing string external surface application life, need to change and repair, increase maintenance cost.In drilling completion process, mounting sleeve rigidity erection device is that to reduce in subsequent casings that flow chart production downhole tool and tubing string external surface and internal surface of sleeve pipe wear and tear between two parties be a problem that can not be ignored to casing centering.
Summary of the invention
The utility model is to solve above-mentioned deficiency, a kind of geological resource is provided to reconnoitre well casing ball-type rigidity erection device, the technical scheme adopted is: there is the supporting rib boss (2) in four roads sleeve pipe ball-type rigidity erection device body (1) outside, be greater than processing in the supporting rib boss (2) of casing coupling external profile diameter and body (1) tube wall at its diameter to be provided with ball sleeve (5) inside ball (3) is installed, in body (1), it is placed in the middle that outer four direction contacts supporting sleeve righting with sleeve pipe (7) and open hole well barrel (8) respectively, ensure cementing quality, be through with cement paste lubrication duct (4) at supporting rib boss (2) and the upper and lower of ball sleeve (5), ensure the rolling lubrication of ball (3) by cement paste effect of setting of casing process sleeve pipe ball-type rigidity erection device.In well drilling well completion casing process, sleeve pipe ball-type rigidity erection device is enclosed within connects on the sleeve pipe of going into the well, and can support casing centering of going into the well object placed in the middle between adjacent casing box cupling and box cupling.
The beneficial effects of the utility model are, in well drilling well completion casing process, sleeve pipe ball-type rigidity erection device is little in ball (3) descending point cantact open hole well wall area of rolling, resistance can be reduced good by performance between two parties at bore hole irregular well section casing centering, the generation of pipe clamp well accident of can avoiding trapping; Supporting rib boss (2) can also be utilized to strike off the mud cake that open hole well barrel (8) sticks, and the clean borehole wall, not only improves displacement efficiency, can also make injection cement paste and cement the well stable between the borehole wall and sleeve pipe; At the irregular uncased wellbore of all kinds of Holes of Complicated Wells, sleeve pipe realizes holding sleeve pipe at the support of open hole well barrel (8) recess face ball (3) point, open hole well barrel (8) convex wall support rib boss (2) face common support at design attitude, ensure that sleeve pipe righting in uncased wellbore is placed in the middle, improve cementing quality, avoid the eccentric wear that in subsequent casings, construction operation production process running string and tool exterior surface and internal surface of sleeve pipe cause, improve sleeve pipe, down-hole string application life, reduce tubing maintenance cost, the object of reducing expenses.

Detailed description of the invention
Be described with reference to the accompanying drawings:
As shown in Figure 1, in well drilling well completion casing process, sleeve pipe ball-type rigidity erection device is sleeved on the sleeve pipe (7) that series sequence goes into the well, supporting rib boss (2) contacts with open hole well barrel (8) with ball (3), the mud cake that open hole well barrel (8) sticks can be struck off by supporting rib boss (2), clean open hole well barrel (8) in its drag effect, promote to go into the well by casing coupling (6), ball (3) rolling point cantact open hole well barrel (8) reduces resistance, to be played by ball (3) and supporting rib boss (2) to design attitude sleeve pipe ball-type rigidity erection device body (1) under sleeve pipe (7) and support the rough borehole wall between adjacent casing box cupling and box cupling, reach the effect that casing centering is placed in the middle, avoid subsequent production tubing string and casing wear.
As shown in Figure 2, be through with cement paste lubrication duct (4) at supporting rib boss (2) and the upper and lower of ball sleeve (5), ensure the rolling lubrication of ball (3) by cement paste effect of setting of casing process sleeve pipe ball-type rigidity erection device.
As shown in Figure 3, there is the supporting rib boss (2) in four roads sleeve pipe ball-type rigidity erection device body (1) outside, be greater than processing in the supporting rib boss (2) of casing coupling external profile diameter and body (1) tube wall at its diameter to be provided with ball sleeve (5) inside ball (3) is installed, realize making in body (1) to design attitude under sleeve pipe, outer four direction supports with sleeve pipe (7) and open hole well barrel (8) fovea superior wall ball (3) point respectively, open hole well barrel (8) convex wall support rib boss (2) face common support holds sleeve pipe, ensure that sleeve pipe righting in uncased wellbore is placed in the middle, ensure cementing quality.
As shown in Figure 4, in well drilling well completion casing process, sleeve pipe ball-type rigidity erection device body (1) is under ball (3) effect, can freely can rotate and upper and lower slip on sleeve pipe, reach righting to act between two parties, effectively prevent casing clamp well, can lower consumption by drag reduction, improve the application life of sleeve pipe and flow string.
