Abstract
The utility model relates to a hydraulic sleeve righting device for completion of a petroleum and geological and mining system, which comprises a body(1), a slide bushing(2), a check cover(3), a seal ring(4), a righting piece assembly(5) and a cover(6). The utility model is novel in design, single in structure and convenient in use. By adopting distending righting piece assembly, the utility model has small resistance in dropping and strong central force, eliminates the sleeve circuiting death area, improves displacement efficiency, enables an annulus to form a cement ring with an even thickness, ensures sealing quality, which is easy to be expended and used.
Description
The utility model relates to a kind of sleeve pipe erection device that is used for oil, the use of Ore System completion.
For making casing centralization, use casing stabbing board usually in the completion process.Elastic centralizer that uses and rigidity centralizer are because its external diameter is bigger at present, can only be used for the conventional well well cementation, and for slim-hole, the well internal diameter is inhomogeneous or bad hole such as window sidetracking, tend to occur not going or being difficult to make down the phenomenon of casing centralization, occur cement after the well cementation and scurry slurry, form cement sheath, the residual drilling fluid of local well section or the landwaste of became uneven, cause sleeve pipe to damage.
The purpose of this utility model be to provide a kind of simple in structure, apparent size is little, is particularly suitable for the fluid pressure type sleeve pipe erection device that bad holes such as the narrow gap of slim-hole, window sidetracking well and well internal diameter be inhomogeneous well cementation is used.
The purpose of this utility model is to realize like this.This kind casing stabbing board is made up of body, sliding sleeve, fluid stopping cover, joint ring, body resistance-strengthening tablets assembly, stop collar.Wherein, body be provided with one week several separatory holes columnar structured, the sliding sleeve that body periphery separatory hole upper and lower end is respectively equipped with not fluid stopping cover slidably and can slides along the body periphery.It between fluid stopping cover and sliding sleeve airtight annular space.The sliding sleeve lower end is provided with the body resistance-strengthening tablets assembly that can slide along the body periphery, and body resistance-strengthening tablets assembly lower end is provided with not interior cartridge type stop collar slidably.
The fluid stopping cover of this fluid pressure type casing stabbing board can be a cirque structure, and sliding sleeve is the cup-shaped structure that the bottom is provided with body through-holes, and the separatory hole on the body is between sliding sleeve upper edge, bottom and fluid stopping cover lower edge.
The fluid stopping cover of this fluid pressure type casing stabbing board can also be the cup-shaped structure of falling that the bottom is provided with body through-holes, and sliding sleeve is established the structure of falling the T-shape of body through-holes in being, the separatory hole on the body puts between the beneath edge with fluid stopping in the sliding sleeve upper edge.
The body resistance-strengthening tablets assembly of this fluid pressure type casing stabbing board can be made up of several equally distributed arcuate bombing leafs that upper/lower terminal is separately fixed at sliding sleeve bottom and stop collar top, and following table is the plane with axis normal on the interior cartridge type stop collar.
This fluid pressure type sleeve pipe holds up the body resistance-strengthening tablets assembly of device to be made up of several equally distributed spring leafs that the upper end is fixed on sliding sleeve bottom, and following table is the plane with axis angle at 45 on the interior cartridge type stop collar.
During completion practice, this device is connected in the sleeve pipe pipe of desired location, sleeve pipe is down behind predetermined well depth, turn on pump injects fluid, fluid enters in the empty lock of airtight annular of sliding sleeve and the formation of fluid stopping cover, and when hydraulic pressure was enough big, the liquid of annular space pushes away advised sliding sleeve descending along the body periphery, make the centralizer axial compression, radially open, thereby make casing centralization, annular space forms uniform gap, be beneficial to circulation well cleanup and well cementation replacement, guarantee cementing quality.
The utility model modern design, simple in structure, easy to use, can directly go up the body resistance-strengthening tablets assembly that expands owing to adopted, the feasible process resistance of transferring is little, power placed in the middle is strong, can effectively eliminate sleeve pipe circulation dead band, improve displacement efficiency, make annular space form the uniform cement sheath of thickness, guarantee the sealing quality, be easy to apply.
Accompanying drawing 1, accompanying drawing 2 are respectively two kinds of structural representations of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is made up of body 1, sliding sleeve 2, fluid stopping cover 3, joint ring 4, body resistance-strengthening tablets assembly 5, stop collar 6.Wherein, fluid stopping cover 3 is cirque structures, and sliding sleeve 2 is provided with the cup-shaped structure of body 1 through hole for the bottom, and the separatory hole on the body 1 is overlapped between 3 lower edges in sliding sleeve upper edge, 2 bottom and fluid stopping.Body resistance-strengthening tablets assembly 5 is made up of several equally distributed arcuate bombing leafs that upper/lower terminal is separately fixed at sliding sleeve 2 bottoms and stop collar 3 tops, and following table is the plane with axis normal on the interior cartridge type stop collar 6.Body is respectively equipped with external screw thread in two ends about in the of 1, is distributed with 1 to 20 aperture on the circumference of middle and lower part and is 1 to 40mm hydraulic pressure hole, and top, hydraulic pressure hole is provided with external screw thread and fluid stopping and overlaps 3 make-ups and tighten.Fluid stopping is overlapped 3 peripheries and is provided with 1 to 10 circumferential slot, is provided with joint ring 4 in the groove.Body resistance-strengthening tablets assembly 5 is made up of 3 to 20 equally distributed arcuate bombing leafs that two ends up and down are separately fixed at sliding sleeve 2 bottoms and stop collar 6 tops.Internal thread that stop collar 6 inner headed faces are provided with and body 1 make-up are tightened, and last following table is the plane with axis normal.
Fig. 2 has provided the structural representation of another kind of fluid pressure type sleeve pipe erection device.Wherein, fluid stopping cover 3 is the cup-shaped structure of falling that the bottom is provided with body 1 through hole, the structure of falling the T-shape that sliding sleeve 2 is established body 1 through hole in being, and the separatory hole on the body 1 is overlapped between the 3 upper base lower edges in sliding sleeve 2 upper edges and fluid stopping.Body resistance-strengthening tablets assembly 5 is made up of several equally distributed spring leafs that the upper end is fixed on sliding sleeve 2 bottoms, and following table is the plane with axis angle at 45 on the interior cartridge type stop collar 6.Body is respectively equipped with external screw thread in two ends about in the of 1, is distributed with 1 to 20 aperture on the circumference of middle and upper part and is 1 to 40mm hydraulic pressure hole, and top, hydraulic pressure hole is provided with external screw thread and fluid stopping and overlaps 3 make-ups and tighten.Establish 1 to 10 circumferential slot on sliding sleeve 2 peripheries, be provided with joint ring 4 in the groove.Body resistance-strengthening tablets assembly 5 is formed for 3 to 20 equally distributed spring leafs that the upper end is fixed on sliding sleeve bottom, and following table is the plane with axis angle at 45 on the stop collar 6.
