Abstract
The utility model relates to a hydraulic bushing reshaper, belonging to the technical field of oil field equipment. The characteristics of the utility model are that: the lower of a tube shape bushing anchor is tightly communicated to the multi stage hydraulic cylinder, whereas the upper of the tube shape bushing anchor is pierced by a plurality of ancryroide bodies; each ancryroide body moveably matches the side wall in the side wall; the bottom of the multi stage hydraulic cylinder is fixedly connected with a reshaping body in which a plurality of cones form a whole cone; a central axis matches the prick face of the whole cone; and the external diameter of the filler ring at the lower of the central axis is larger than the inner hole of the whole cone. Thus the utility model has the beneficial effects of novel design, reasonable structure, strong repairing and sit changing capacity and well effect; moreover, the bushing is cooled to harden after repairing, thus the outer squeeze resistant capacity is enhanced.
Description
Technical field
The utility model belongs to the oil field equipment technical field.
Background technology
In oil field development is produced, down-hole casing produces local necking deformation because of influenced by the kinds of processes measure to be directed at Casing Failure, oil pump is hung up carry the reduction submergence, influence pump efficiency, the conventional instrument of oil-water well can not normally remove, have a strong impact on the oil field and normally develop, therefore cover change shaping reparation is of great importance to oil field raising output and stable yields.The oil field is to the existing pyriform tube expander of the kind of casing deformation fix tool and technology, the eccentric roller reshaper, third hand tap roller shell pipe reshaper, rotation jarring formula casing mandrel and explosive shaping etc., the drilling tool of these shaping tools and these shaping tools of driving is affected its intensity because of being subjected to the casing size restriction, shaping effect also is affected and limits, and blast damages sleeve pipe.Above-mentioned cover instrument and the technology controlled is owing to being subjected to all multifactor influences to fail to be widely used in production.
Summary of the invention
The purpose of this utility model is:
A kind of hydraulic pressure casing mandrel that utilizes ground hydraulic power that down-hole casing is repaired is provided.
The technical solution of the utility model is:
The hydraulic pressure casing mandrel is to be combined by sleeve pipe anchor, multistage hydraulic cylinder, shaping body.
Tubular sleeve pipe anchor lower end is communicated with multistage hydraulic cylinder is airtight, the sidewall of sleeve pipe anchor upper end has crossed several anchor tooth bodies, each anchor tooth body is in sidewall and snug engagement, be fixedly connected with the shaping body in the multistage hydraulic cylinder bottom, in the shaping body, constitute a whole cone by number lobe cone, axle is that the tapering face cooperates with the shaping awl, and axle lower end filler ring external diameter is greater than shaping awl mouthful endoporus.
The beneficial effects of the utility model are:
Modern design, rational in infrastructure, reparation cover change ability is strong, and shaping effect is good, repairs back well section sleeve pipe and is subjected to flow harden, anti-outer extrusion capability enhancing.
Description of drawings
Fig. 1 is the utility model structure sectional view;
Fig. 2 is the utility model A-A sectional view;
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, the 1st, sleeve pipe anchor, the 2nd, multistage hydraulic cylinder, the 3rd, shaping body; A anchor tooth body, b and c piston rod duct, d fluid cylinder chamber, e cylinder body, f axle, g shaping awl, h filler ring, k piston rod.
The a spare of sleeve pipe anchor 1 has a plurality of anchor tooth bodies, and hydraulic cylinder 2 is multistage hydraulic cylinders, and the big end of shaping awl g in the shaping body 3 is many lobes cone, helps breathing.Axle f and shaping awl g is that the tapering face cooperates, can prevent that when crowded expansion set height shaping from boring g and being out of shape.Axle f lower end filler ring h external diameter prevents that greater than shaping awl g endoporus shaping awl g breaks away from axle f.
During use, sleeve pipe anchor 1, multistage hydraulic cylinder 2 and shaping body 3 are each other with being threaded.And with arriving distortion well section under the oil pipe.When the ground highly pressurised liquid arrives sleeve pipe anchor and hydraulic cylinder place through tubing string, highly pressurised liquid is released anchor tooth body and sleeve pipe grappling, highly pressurised liquid in the hydraulic cylinder enters by piston rod duct b, c that to promote cylinder body e in the d of fluid cylinder chamber descending, and cylinder body e promotes axle f and shaping awl g is descending, and the descending distortion well section that runs into of shaping awl g is squeezed bloated until meeting the requirements.If 200 millimeters of fluid cylinder one strokes are during less than distortion well section, oil pipe release anchor tooth body a is resetted by the flat spring effect, piston rod k is with oil pipe descending 200 millimeters when transferring tubing string, ground is beaten highly pressurised liquid to oil pipe once more and is realized the above-mentioned course of work, till distortion well section is all squeezed the bloated run through casing size that meets the requirements.
