Abstract
The utility model discloses a resin spiral sleeve pipe centralizer, including righting body and gyro wheel, still including the spiral righting strip and spiral whirl groove, the spiral righting strip distributes on righting the body with spiral whirl groove, and the gyro wheel distributes on the spiral righting strip. The utility model provides a put the too big problem of sleeve pipe rigidity of centralizer, can reduce the sleeve pipe cluster rigidity, also can right the sleeve pipe to reduce the lower casing and rub and hinder, can also improve later stage well cementation quality.
Description
Technical field
The utility model relates to the sleeve pipe of different sleeve pipes in casing job and sets upright centering means, relates in particular to a kind of resin screw shell centralizer.
Background technology
In practical application, sleeve pipe is lowered in the well process need place centralizer, and casing stabbing board kind of the prior art is numerous; For example, Chinese patent number " 200720148974.X " discloses a kind of roller type screw shell centralizer, cased hole completion field when belonging to oil or geology production drilling; Its open day is on February 20th, 2008; Comprise centralizer body, the said centralizer body outside is provided with wiper block, and said wiper block is a helical form; Be provided with roller between two adjacent wiper blocks, said roller is installed on the wiper block through bearing pin; Said centralizer body side is provided with positioning screw hole.
But find that in practical application also there is following deficiency in existing centralizer: one, the centralizer rigidity is excessive, causes down-hole accident easily, or the righting strip poor quality causes down-hole accident, has bigger potential safety hazard.Two, the later stage cementing quality is difficult for guaranteeing.
Summary of the invention
The purpose of the utility model is to overcome the problems referred to above that existing casing stabbing board exists; A kind of resin screw shell centralizer is provided; The utility model solves the excessive problem of sleeve pipe rigidity of putting centralizer, can reduce the bunch tube rigidity, also can set upright sleeve pipe; And reduce Frictional Drag of Casing Running, can also improve the later stage cementing quality.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
A kind of resin screw shell centralizer comprises centralizer body and roller, it is characterized in that: also comprise spiral righting strip and spiral eddy flow groove, said spiral righting strip and spiral eddy flow groove are distributed on the centralizer body, and roller is distributed on the spiral righting strip.
Said centralizer body is tubular resin centralizer body.
The evenly spiral distribution of described spiral righting strip on the centralizer body surface.
The evenly spiral distribution of described spiral eddy flow groove on the centralizer body surface.
The quantity of described roller is five perhaps multiples of five.
Adopt the advantage of the utility model to be:
One, the utility model is a resin spiral roller centralizer; Can solve the excessive problem of sleeve pipe rigidity that places centralizer; Reduce the bunch tube integral rigidity behind the centralizer body material modification; The spiral righting strip is set upright sleeve pipe, and the Frictional Drag of Casing Running that reduces through the roller maximum can improve the later stage cementing quality through the spiral stream guidance groove.
Two, in the utility model, said centralizer body is tubular, and when using with sleeve kit, matching is better, improves efficiency of construction.
Three, in the utility model, described spiral righting strip on centralizer body surface evenly spiral distribute, and set upright best results after sleeve pipe cooperates.
Four, in the utility model, the evenly spiral distribution of described spiral eddy flow groove on the centralizer body surface, this distribution mode makes the later stage cementing quality reach best.
Six, in the utility model, the quantity of described roller is five perhaps multiples of five, makes frictional force reduce to minimum.
Description of drawings
Fig. 1 is the utility model structural representation
Be labeled as among the figure: 1, centralizer body, 2, the spiral righting strip, 3, spiral eddy flow groove, 4, roller.
The specific embodiment
A kind of resin screw shell centralizer comprises centralizer body 1 and roller 4, also comprises spiral righting strip 2 and spiral eddy flow groove 3, and said spiral righting strip 2 is distributed on the centralizer body 1 with spiral eddy flow groove 3, and roller 4 is distributed on the spiral righting strip 2.
The preferred implementation of the utility model does, said centralizer body 1 is tubular resin centralizer body, and this is a best mode.
The another preferred implementation of the utility model does, described spiral righting strip 2 on the axle apparent direction surface of tubular centralizer body 1 evenly spiral distribute, quantity is five.
The another preferred implementation of the utility model does, described spiral eddy flow groove 3 on the axonometric drawing surface of tubular centralizer body 1 evenly spiral distribute, quantity is five.
The another preferred implementation of the utility model is that the quantity of described steel roller 4 is five perhaps multiples of five.
