Abstract

The utility model relates to a centering guide device. The centering guide device comprises a threaded connection part and a guide shoe, and is characterized by the further inclusion of a centering device, centering blocks are uniformly distributed outside the centering guide device, and an oblique guide port is formed at the lower end of the guide shoe. The centering guide device has the advantages that when a tool string of the guide shoe for centering guide is lowered, large external diameters of the centering blocks can guarantee the centering of the guide shoe at the lower part and ensure that the guide shoe is not blocked; and the oblique guide port is further formed at the lower end of the guide shoe, so that the continuous and smooth lowering of the tool string is facilitated. The centering guide device has simple structure and low manufacturing cost, and improves the success rate and the efficiency of lowering well completion tools into the design positions of a horizontal well, a large-displacement well and a highly-deviated well.

Description

Set upright guiding device
Technical field
The utility model belongs to the oilfield exploitation technical field, particularly relates to a kind of guiding device of setting upright.
Background technology
The used guide shoe of oilfield well completion all is the corresponding direction of chamfering opening at present, in the process that tool string is being lowered to, big latus rectum guide shoe planar end surface in the known technology is after the step place is hampered, just be difficult to continue to be lowered to, it is not in place particularly to cause completion tool to be lowered to easily when horizontal well, extended reach well and high angle hole completion, and then has influenced production operation.
Summary of the invention
The utility model is for solving the guiding device of setting upright that can change the lower end targeting port direction that is lowered to guide shoe when the technical problem that exists in the known technology provides a kind of the use.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of guiding device of setting upright comprises threaded joints and guide shoe, it is characterized in that: also include erection device, erection device comprises and is evenly distributed on the wiper block of setting upright the guiding device outside that the guide shoe lower end is provided with oblique targeting port.
The utility model can also adopt following technical scheme:
The quantity of described wiper block is three.
Described wiper block lower end is provided with the inclination angle, and the inclination angle is 75 °, can play the effect that instrument placed in the middle is gone into well of setting upright.
The angle of described oblique targeting port is 45 °, guarantees that completion tool is lowered into the success rate and the efficient of horizontal well, extended reach well and high angle hole position.
Advantage and the good effect that the utlity model has are:
Because the utility model has adopted technique scheme, the tool string of setting upright the guiding guide shoe in use is lowered to process, and the big external diameter of wiper block can guarantee the placed in the middle of bottom guide shoe, guarantees that guide shoe is not hampered, simultaneously the guide shoe lower end angle that leads in addition is beneficial to tool string and continues to be lowered to smoothly.It is simple in structure, and low cost of manufacture has improved success rate and efficient that completion tool is lowered into horizontal well, extended reach well and high angle hole design attitude.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a stereogram of the present utility model.
Among the figure: 1, threaded joints; 2, erection device; 2-1, wiper block; 2-2, inclination angle; 3, guide shoe; 3-1, oblique targeting port.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of guiding device of setting upright, comprise threaded joints 1 and guide shoe 3, also include erection device 2, erection device 2 comprises and is evenly distributed on three wiper block 2-1 that set upright the guiding device outside, described wiper block lower end is provided with the inclination angle, and the inclination angle is 75 °, can play the effect that instrument placed in the middle is gone into well of setting upright.Guide shoe 3 lower ends are provided with oblique targeting port 3-1, and the angle of described oblique targeting port is 45 °, guarantee that completion tool is lowered into the success rate and the efficient of horizontal well, extended reach well and high angle hole position.
Operating principle of the present utility model is:
Completion tubular column uses when setting upright the guiding guide shoe and is connected by other devices of threaded joints 1 and upstream, guiding completion tubular column G.I.H.The big external diameter of the wiper block 2-1 of erection device 2 can guarantee guide shoe 3 placed in the middle of bottom, guarantees that guide shoe 3 is not hampered, and guide shoe part lower end also has oblique targeting port 3-1 simultaneously, is beneficial to tool string and continues to be lowered to smoothly.Originally it is simple in structure to set upright guiding device, and low cost of manufacture has improved success rate and efficient that completion tool is lowered into horizontal well, extended reach well and high angle hole design attitude.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
