Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, present embodiments provide a kind of Casing Failure reshaper, this Casing Failure reshaper comprises: adapter sleeve 3, power part and shaping portion, adapter sleeve 3 has pressure transmission hole, pressure transmission hole is for connecting the infusion pipeline of ground pump truck, the first end of the interior moving member of power part is communicated with adapter sleeve 3 and is set in adapter sleeve 3 movably, the first end of the outer moving member of power part is fixedly connected with adapter sleeve 3, wherein, shaping portion comprises ball axle 13, ball sleeve 12 and ball 14, ball axle 13 is fixedly connected with the second end of interior moving member, ball sleeve 12 is set on ball axle 13, the first end of ball sleeve 12 is fixedly connected with on the second end of moving member outside, second end of ball sleeve 12 forms sealed end, ball sleeve 12 offers the ball hole for installing ball 14, ball axle 13 is provided with coordinate with ball 14 there is special angle taper surface.
Application the technical solution of the utility model, this Casing Failure reshaper has ball axle, ball sleeve, ball and power part, ball axle is fixedly connected with the interior moving member of power part, by adapter sleeve by liquid input power portion, thus moving member moves to drive ball axle to move in driving, owing to ball axle being provided with the taper surface with ball engagement, ball axle is made to extrude ball extending radially out along ball axle, and ball rotates under the drive of ball axle, such ball can carry out roll extrusion shaping to Casing Failure, make, Casing Failure internal diameter is increased, to realize expanding time rounding shape of Casing Failure.Because Casing Failure reshaper of the present utility model leans on the deadweight of himself tubing string to carry out self-locking, make reshaper stably can be locked in the distortion pipeline section place of Casing Failure, do not need to carry out grappling with anchor watt to Casing Failure, and corresponding ball position is processed with the special angle conical surface on ball axle, and can self-weight self-locking be realized and by accommodating pressure-transmitting liquid driven plunger due to this reshaper, make reshaper move along Casing Failure outbound course and carry out tube and (namely achieve reverse tube, in prior art, tube direction is the input direction of Casing Failure).Therefore, this reshaper can not cause any infringement to Casing Failure, ensure that the integrality of Casing Failure.
In the present embodiment, power part comprises central tube 4, piston bush 6 and piston 8, piston bush 6 is set on central tube 4, first end and the adapter sleeve 3 of piston bush 6 are tightly connected, the first end of central tube 4 can be arranged in adapter sleeve 3 movably, second end of central tube 4 is fixedly connected with ball axle 13, piston 8 is arranged in the plunger shaft between central tube 4 and piston bush 6, and central tube 4 and piston 8 are with being dynamically connected, preferably, be connected by key 7 between piston 8 with central tube 4, central tube 4 correspondingly offers pressure transmission hole 5, wherein, be communicated with to carry liquid between adapter sleeve 3 with central tube 4.The power part of the present embodiment by hydraulic way driven plunger 8, thus makes central tube 4 move with piston 8, thus central tube 4 drives ball axle 13 to move to extrude ball 14, and hydraulically powered power is more stable, and drive efficiency is high.
In order to improve the Power output of power part further to strengthen the ability to work in the shaping portion of reshaper, the piston bush 6 of this Casing Failure reshaper has multiple, piston 8 has multiple, multiple piston bush 6 connects successively, forms the plunger shaft for installing each piston 8 between each piston bush 6 and central tube 4.By the Power output of multiple piston 8, ball 14 pairs of Casing Failure are made to have stronger squeezing shaping ability.
Drive owing to utilizing hydraulic power, in order to the gap better between packed-piston cover 6, central tube 4 and piston 8, ensure that situation about revealing does not appear in liquid, first seal 10 is installed between piston 8 and central tube 4 and the second seal 11 is installed between piston 8 and piston bush 6, and be provided with the 3rd seal 9 between the second end of piston bush 6 and central tube 4, pressure transmission hole 5 is between the first seal 10 and the 3rd seal 9.
In the present embodiment, because Casing Failure reshaper needs to put in from oil-water well well head smoothly to need the pipeline section of the Casing Failure of shaping in oil-water well, therefore, Casing Failure reshaper also comprises guide head 15, and guide head 15 is tightly connected to form sealed end with the second end of ball sleeve 12.Further, in order to better realize the guide effect of guide head 15, the guide head 15 of this reshaper is elliposoidal.
The better effects if of the shaping Hui Yuan of the pipeline section of the Casing Failure after completing to make shaping, well, therefore, ball hole is array distribution along the circumference of ball sleeve 12 for the caliber of the Casing Failure after Hui Yuan and the match of pipe diameter of crude water casing.Under the driving of hydraulic power, make the ball 14 of hundreds of steels progressively stretch out ball hole and arrive the size preset, then, ball axle 13 continues to continue under the promotion of hydraulic power to force hundreds of balls 14 overhanging to carry out expanding and roll extrusion to the inwall of Casing Failure, makes the thorough roll extrusion of Casing Failure return cake and progressively returns to design latus rectum.
In the present embodiment, ball hole is the bellmouth of the radial direction convergent along ball sleeve 12, and ball 14 is embedded in bellmouth actively.Ball is being assembled in the process of ball hole by assembly crewman, first can cool ball 14 with the diameter of shrinkage ball 14, and ball sleeve 12 is heated the aperture expanding ball hole, be then embedded in ball hole by ball 14.Like this, after ball sleeve 12 and ball 14 are returned to normal temperature state, the minimum-value aperture of ball hole is less than the diameter of ball 14, makes ball 14 to drop out ball hole.
Preferably, Casing Failure reshaper also comprises lifting sub 2, and the first end of lifting sub 2 is connected with adapter sleeve 3 and lifting sub 2 is communicated with adapter sleeve 3, and the second end of lifting sub 2 is used for being connected with infusion pipeline.Infusion pipeline is communicated with adapter sleeve 3 by lifting sub 2 by top connection 1, thus makes the connection between infusion pipeline and Casing Failure reshaper more reliable.
In the process of the ironing of roll extrusion repeatedly Casing Failure, Casing Failure is Hui Yuan progressively, and make the distortion pipeline section of Casing Failure realize plasticity to reply, thus improve the hardness of parallel pipeline section, also can reduce the resilience possibility of Casing Failure, achieve the construction object being issued to the distortion pipeline section expanding time rounding shape making Casing Failure in the prerequisite not injuring Casing Failure.
Through on-the-spot application attestation, the reliable in mechanical performance of this reshaper, its pressure-bearing can reach 20MPa, and after the supercharging of the piston-type hydro pressure power of the present embodiment, the active force be communicated on ball 14 can reach 650KN.The structure of this reshaper is simple, reasonable in design, and convenient operation person operation; This reshaper is safe and reliable, does not damage sleeve pipe; Operating efficiency is high, thus shortens the duration, reduces construction operation cost.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
