Abstract
The utility model relates to the technical field of a guiding device used for a connecting oil pipe in a well, in particular to a guider for the connecting oil pipe. The guider comprises a cylinder body and a guiding head, wherein the guiding head is fixed at the lower end of the cylinder body and is in a hemisphere shape, and a through hole communicated with an inner cavity of the cylinder body is arranged in the guiding head; at least two spraying holes are arranged at the lower part of the cylinder body; the guider is reasonable and compact in structure, the guiding head is in a hemisphere shape, the hemisphere shape structure can reduce the contact area of the guiding head and the pipe wall, thereby reducing the contact friction force; meanwhile, the spraying holes generate counter force for the guiding head body when spraying liquid, thereby preventing the guiding head from being blocked; and the guider is simple and convenient in use, can facilitate the more flexible dropping of the connecting oil pipe, so that the connecting oil pipe can smoothly reach a specified construction position.
Description
Technical field
The utility model relates to the device technique field that is used for connecting in the well oil pipe guiding, is a kind of connection oil pipe guider.
Background technology
According to the site work needs, coiled tubing will arrive assigned address by the oil well passage, the straight well section, lower curved section and the net horizontal section that hang step are arranged in the oil well passage, and when the connection oil pipe dropped to these positions, regular meeting hung the step place because of coiled tubing is against and can not move on; Particularly enter the long well of horizontal segment greater than 90 ° requirement at deep-well, ultradeep well, hole angle, make coiled tubing pass through step if only rely on ground to exert pressure, coiled tubing then easily takes place can't be continued to descend in certain the step place accumulation that intercepts coiled tubing, sinusoidal deadlock phenomenon occurs, can't arrive predetermined well section and carry out set construction operation.
Summary of the invention
The utility model provides a kind of connection oil pipe guider, has overcome the deficiency of above-mentioned prior art, and it can effectively solve and connect the step place easily stuck problem of oil pipe in the oil pipe passage.
The technical solution of the utility model realizes by following measure:
Be further optimization and/or improvements below to above-mentioned utility model technical scheme: a kind of connection oil pipe guider, comprise cylindrical shell and guide head, the lower end of cylindrical shell is fixed with guide head, and it is hemispherical that guide head is, and the through hole that communicates with cylinder lumen is arranged in guide head.
At least two spray-holes can be arranged at the bottom of above-mentioned cylindrical shell.
Above-mentioned spray-hole can be the oblique hole that is directed downwards.
Four spray-holes that are uniformly distributed along the circumference can be arranged at the bottom of above-mentioned cylindrical shell.
The utility model reasonable and compact in structure, guide head are hemispherical, and hemispherical structure can reduce the contact area of guide head and tube wall, thereby have reduced contact friction force; During the liquid of spray-hole ejection simultaneously, guide head itself there is reaction force, can avoids guide head to be stuck; This structure is easy to use, and it is more flexible that the connection oil pipe is descended, and makes to connect the construction location that oil pipe can arrive its appointment smoothly.
Description of drawings
Accompanying drawing 1 for the utility model with is connected oil pipe, connection oil connection, hydraulic pressure is given up and one way valve links together leads and look the partial cutaway structural representation.
Accompanying drawing 2 is that the A-A of accompanying drawing 1 is to sectional view.
Coding in the accompanying drawing is respectively: 1 for connecting oil pipe, and 2 for connecting oil connection, and 3 give up for hydraulic pressure, and 4 is one way valve, and 5 is guide head, and 6 is spray-hole, and 7 is through hole, and 8 is cylindrical shell.
The specific embodiment
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
In the utility model, for convenience of description, the description of the relative position relation of each parts all is that the Butut mode according to Figure of description is described, as: the position relation of upper and lower, left and right etc. is what to determine according to the Butut direction of Figure of description.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
As shown in Figure 1, this connection oil pipe guider comprises cylindrical shell 8 and guide head 5, and the lower end of cylindrical shell 8 is fixed with guide head 5, and guide head 5 is hemispherical, and the through hole 7 that communicates with cylindrical shell 8 inner chambers is arranged in guide head 5.
Can according to actual needs above-mentioned connection oil pipe guider be made further optimization and/or improvements:
As shown in Figure 1, in the bottom of cylindrical shell 8 at least two spray-holes 6 are arranged.
As shown in Figure 1, the oblique hole of spray-hole 6 for being directed downwards; Oblique hole is big with respect to the flow velocity that lateral aperture sprayed, and has improved the scouring capability of spray-hole 6; Because the effect of oblique hole direction makes obstructs such as guide head 5 easier disengaging steps.
As shown in Figure 2, four spray-holes that are uniformly distributed along the circumference 6 are arranged in the bottom of cylindrical shell 8; Like this, can act on simultaneously, guide head 5 is not partial at four direction.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
The use of the utility model most preferred embodiment: will connect oil pipe 1, connect oil connection 2, hydraulic pressure gives up 3, one way valve 4 and utility model install from top to bottom successively, and put it in the oil pipe passage, and move downward by himself gravity; When having step or attachment to intercept in the oil pipe passage, because guide head 5 is hemispherical, the reaction force during simultaneously again by spray-hole 6 ejection liquid can break away from utility model and intercepts and continue to move downward, to arrive assigned address.
Claims (4)
1. one kind connects the oil pipe guider, it is characterized in that comprising cylindrical shell and guide head, and the lower end of cylindrical shell is fixed with guide head, and it is hemispherical that guide head is, and the through hole that communicates with cylinder lumen is arranged in guide head.
2. connection oil pipe guider according to claim 1 is characterized in that at least two spray-holes are arranged at the bottom of cylindrical shell.
3. connection oil pipe guider according to claim 2 is characterized in that spray-hole is the oblique hole that is directed downwards.
