Abstract
The utility model relates to a spiral rigid resin centralizer device which comprises a centralizer shell body (1) and a positioning screw (2). The spiral rigid resin centralizer device is characterized in that the centralizer shell body (1) is of a spiral rigid resin structure. The spiral rigid resin centralizer device has the advantages that the rigid centralizer is installed on a sleeve pipe and used for centering the sleeve pipe, a centering strip is designed to be in a spiral shape, eddies can be generated by fluid, displacement of mud is facilitated, the circulation area is increased, the mud is fully contacted with a well wall, therefore, the sleeve pipe is centered, and the sleeve pipe is prevented from being stuck and clamped.
Description
Technical field
The utility model relates to setting upright the spiral rigid resin centralizer device of sleeve pipe.
Background technology
The rigidity centralizer is contained on the sleeve pipe, is used for setting upright sleeve pipe.The existing sleeve pipe of setting upright mostly is tubular structure, and this structure can not make fluid produce eddy current, is unfavorable for the replacement of mud, reduces the area that circulates, and can not make mud contact the borehole wall fully, can not make casing centralization, the sticking card of sleeve pipe occurs.
The utility model content
The purpose of this utility model provides a kind of replacement that is conducive to mud, increases the circulation area, and mud contacts the borehole wall fully, thereby makes casing centralization, prevents the spiral rigid resin centralizer device of the sticking card of sleeve pipe.
The purpose of this utility model is achieved in that spiral rigid resin centralizer device, comprises centralizer housing and dog screw, it is characterized in that: the centralizer housing is spiral rigid resin structure.
On the centralizer convex surface of described spiral rigid resin structure dog screw is arranged.
The internal diameter of described centralizer housing 142 and 182mm between, external diameter is at 210mm, length is at 150 ± 1mm.
The utility model has the advantages that: the rigidity centralizer is contained on the sleeve pipe, is used for setting upright sleeve pipe.Its righting strip is designed to helical form, can make fluid produce eddy current, is conducive to the replacement of mud, increases the circulation area, and mud contacts the borehole wall fully, thereby makes casing centralization, prevents the sticking card of sleeve pipe.
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Description of drawings
Fig. 1 is the utility model example structure schematic diagram;
Among the figure, 1, the centralizer housing; 2, dog screw; 3, convex-concave helical form.
The specific embodiment
Embodiment 1
As shown in Figure 1, spiral rigid resin centralizer device, comprise centralizer housing 1 and dog screw 2, it is characterized in that: centralizer housing 1 is spiral rigid resin structure 3, on the centralizer convex surface of spiral rigid resin structure 3 dog screw 2 is arranged, the internal diameter of centralizer housing 1 is at 142 mm ± 0.2 mm, and external diameter is at 210mm, and length is at 150 ± 1mm.
Embodiment 2
As shown in Figure 1, spiral rigid resin centralizer device, comprise centralizer housing 1 and dog screw 2, it is characterized in that: centralizer housing 1 is spiral rigid resin structure, on the centralizer convex surface of spiral rigid resin structure dog screw 2 is arranged, the internal diameter of centralizer housing 1 is in 182 mm ± 0.2, and external diameter is at 210mm, and length is at 150 ± 1mm.
The internal diameter of centralizer housing 1 of the present utility model 142 and 182mm between, external diameter is at 210mm, length can at 150 ± 1mm.
The spiral rigid resin centralizer device that what embodiment 1 provided in the utility model is 5 1/2 " spiral rigid resin centralizer device, what embodiment 2 provided is 7 ".Mounting method of the present utility model is: unclamp jackscrew spiral rigid resin centralizer device is enclosed within sleeve shell, select correct position and tighten jackscrew to get final product, with sleeve pipe access tube string.
Note nothing damage crack, surface before of the present utility model the going into the well, the size conforms standard, the jackscrew screw thread is intact.
