Description
Technical field
The utility model relates to the servicing machine of field of petroleum exploitation, specifically the reparation frock of oil-water well indent sleeve pipe.
Background technology
Casing Failure usually can Inward deflection occur because of crustal movement or misoperation, and the sleeve pipe of Inward deflection can't enter in the well oil exploration equipment, and this can have influence on the normal production of oil-water well, even may cause oil-water well to stop production.In order to improve the utilization rate of oil-water well, increase the output of oil, the sleeve pipe reparation of concave distortion seems particularly important, yet oil-water well has certain degree of depth, the casing repairing difficulty of Inward deflection is large, now people's operating process when repairing the sleeve pipe of indent is loaded down with trivial details, waste time and energy, and cost is high.
The utility model content
The purpose of this utility model is to solve the problem that operating process when repairing now Inward deflection sleeve pipe in the oil-water well is loaded down with trivial details, waste time and energy, and provides a kind of and is convenient to realize, the reparation frock of the oil-water well indent sleeve pipe of simple operation.
The purpose of this utility model is achieved through the following technical solutions: the reparation frock of oil-water well indent sleeve pipe, comprise the supervisor, the first expansion arc, positioning pipe, the second expansion arc and the end socket that connect in turn from top to bottom, described the first expansion arc is the 3rd expansion tube, described the 3rd expansion tube sidewall is spliced to form by a plurality of evagination circular arc wall and a plurality of indent circular arc wall annular, and described the second expansion arc comprises the first expansion tube, tube connector and the second expansion tube that connects in turn from top to bottom.The utility model places in the oil-water well when using, first the second expansion arc is placed on the position of sleeve pipe Inward deflection, if the position of Inward deflection is less, then place the position of Inward deflection to get final product the first expansion tube or the second expansion tube, after the second expansion arc is placed on the position of sleeve pipe Inward deflection, in the utility model, add pressure fluid, at this moment, the first expansion tube and the second expansion tube expand, tube connector is indeformable, the utility model pushes the sleeve pipe of Inward deflection by the expansion of the first expansion tube and the second expansion tube, and then the sleeve pipe of finishing concave distortion carries out elementary reparation.Then, reduce the position of the utility model in oil-water well, the first expansion arc is placed the position of sleeve pipe Inward deflection, pass into pressure fluid, by the expansion of the first expansion arc the position of sleeve pipe Inward deflection is repaired again, so, the utility model pushes the sleeve pipe of Inward deflection by the expansion of expansion tube, and then finishes the reparation of the sleeve pipe of concave distortion.
Be provided with the dividing plate that is connected with its inner wall sealing in the described positioning pipe, described dividing plate is connected with the feed tube that runs through its upper and lower end face.The utility model is separated the first expansion arc and the second expansion arc by dividing plate, and can independently add pressure fluid to the second expansion arc by feed tube, so, and the control of being more convenient for when the utility model is used.
Described end socket comprises the lower shrouding of guide pipe and sealing guide pipe lower ending opening, and the second expansion tube of described the second expansion arc is connected with end socket by being connected on the guide pipe.The utility model makes the second expansion arc have a transition conduit between the lower shrouding under the effect of guide pipe, rather than directly seal the second expansion tube lower ending opening of the second expansion arc, so, can guarantee the firm of the utility model lower end structure behind the injection pressure liquid.
Because of the position of sleeve pipe Inward deflection so that the inside irregular contraction of sleeve pipe, for the ease of the position of end socket by Inward deflection, in order to guarantee that guide pipe passes the position that the second expansion arc behind the position of sleeve pipe Inward deflection can be placed in the sleeve pipe Inward deflection, the internal diameter of described guide pipe is less than supervisor's internal diameter, and the internal diameter of described tube connector is less than the internal diameter of guide pipe.
In order to guarantee that the first expansion arc can be placed in the position of sleeve pipe Inward deflection, the internal diameter of described positioning pipe is between supervisor's internal diameter and guide pipe internal diameter.
As preferably, the quantity of described the 3rd expansion tube protruding circular arc wall in China and foreign countries and indent circular arc wall is three, any one evagination circular arc wall all is connected with two indent circular arc wall in three evagination circular arc wall, and any one indent circular arc wall all is connected with two evagination circular arc wall in three indent circular arc wall.
Because bellows is convenient to draw materials, and have good telescopicing performance, as preferably, described the first expansion tube and the second expansion tube are bellows.
Compared with prior art, the utlity model has following beneficial effect: when (1) the utility model is used expansion tube is placed sleeve pipe Inward deflection position, and make expansion tube expand to finish reparation to sleeve pipe Inward deflection position by adding pressure fluid, the integrated operation process is convenient, with low cost, time saving and energy saving.
(2) the utility model comprises the first expansion arc and the second expansion arc, when using, first the second expansion arc is placed the position of sleeve pipe Inward deflection to carry out elementary reparation, place the position of sleeve pipe Inward deflection again to repair the first expansion arc again, by twice reparation, can improve repairing quality.
(3) the larger sleeve pipe of the utility model application hour hands concave distortion is repaired by the second expansion arc first, when the second expansion arc is repaired sleeve pipe, tube connector is indeformable, and the sleeve pipe that so can prevent concave distortion stress occurs when carrying out elementary reparation and concentrates.
(4) the 3rd expansion tube of the present utility model is spliced to form by a plurality of evagination circular arc wall and a plurality of indent circular arc wall annular, so that the position of sleeve pipe Inward deflection diminishes, the utility model is convenient to repair internal surface of sleeve pipe more level and smooth by the arc structure of the 3rd expansion tube when again repairing after the second expansion arc carries out elementary reparation.
