Abstract
The utility model relates to a casing damaged well shaping diameter expanding cable tool impacter in the oil field; because a mechanical cable tool impacter with simple structure is used for replacing a fluid-pressure-type cable tool impacter with complicated structure, the fabrication cost is low. The casing damaged well shaping diameter expanding cable tool impacter prolongs the lower end joint (6) of the descent boring tool, and a prolonging body is a mandrel (1) with a center pore passage; the outside of the mandrel is coated with a coat (3), and the upper end of the coat is connected and sheathed with the sliding bush (2) on the mandrel in a screw thread way. The lower end of the coat is connected with a screw thread joint (5) with the center pore passage in a screw thread way, and the joint is connected with an expanding pipe shaper; the lower end of the mandrel is connected with a cable tool impact baffle ring (4) in a screw thread way so as to form the cable tool impacter; the cable tool impact baffle ring is lifted along with the mandrel by the boring tool and generates bit shift in the coat, and the cable tool impact can be generated when the direction is changed.
Description
The utility model relates to oil field cover (pipe) and decreases (bad) well shaping hole enlargement cable tool impacter.
Existing cover decreases in the oil-water well overhaul pipeline technology, cover is decreased position mechanical shaping hole enlargement, be to be lowered to an expanding tube reshaping device, drive the expanding tube reshaping device and cover is decreased the position pause repeatedly and hit, make cover decrease that recover fully at the position or part returns to former casing inner diameter by raising and decentralizing drilling rod with drilling rod.Its shortcoming is: (1) every is hit once, and the expanding tube reshaping device all will leave cover and decrease the position, and shaping hole enlargement efficient is low.(2) for sleeve pipe bad break well, because of the bad break mouth departs from the sleeve pipe center line, can not guarantee the expanding tube reshaping device exactly to bad break mouth shaping hole enlargement, shaping hole enlargement success rate is low.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and tube expander does not break away from the casing damaged well shaping hole enlargement cable tool impacter of original position when providing a kind of to hit.
The purpose of this utility model can reach by the following technical programs: prolong end joint under the drilling tool of going into the well, extension body is equipped with overcoat, the sliding sleeve of upper end screw thread adapter sleeve outside mandrel of this overcoat for the mandrel of band centre bore outside this mandrel; The nipple of the lower end screw thread connecting band centre bore of overcoat, this joint connects the expanding tube reshaping device; Be threaded in the lower end of above-mentioned mandrel and time hit baffle ring.By above this cable tool impacter of forecast scheme configuration, wherein the cable tool impacter baffle ring can produce upper and lower displacement slip with mandrel, by moment slip to the lower end from the upper end, pause and hit on the nipple of the band centre bore that overcoat lower end snail line connects, make under the impulse force that weight produced of top drilling tool and pass to the expanding tube reshaping device, as piling, make the expanding tube reshaping device be subjected to constantly pausing hitting, can finish this purpose.
The utility model is compared with above-mentioned present technology can have following effect: this cable tool impacter upper end is connected drilling tool with the joint of belt carcass axle, the lower end connects expanding tube reshaping device (or coupling part drilling tool after again connect expanding tube reshaping device) by the joint that puts outward, pause on the mandrel and hit baffle ring with in the mandrel generation, bottom offset, by moment slip to the lower end from the upper end, pause and hit on the nipple of the band centre bore that overcoat lower end snail line connects, make under the impulse force that weight produced of top drilling tool and pass to the expanding tube reshaping device, constantly be subjected under the situation that the expanding tube reshaping device is carried on not timing and hit, can improve the effect of shaping hole enlargement.
Accompanying drawing is this cable tool impacter half sectional view.
Below by accompanying drawing the utility model is further described:
Shown in accompanying drawing, prolong end joint [6] under the drilling tool of going into the well, extension body overlaps overcoat [3], the sliding sleeve [2] of the upper end screw thread adapter sleeve of overcoat [3] on mandrel [1] for the mandrel [1] of band centre bore outside this mandrel; The screw thread male joint [5] of the lower end screw thread connecting band centre bore of overcoat [3], this joint is connected with the expanding tube reshaping device, or is connected with the expanding tube reshaping device by the part drilling tool; Be threaded in the lower end of above-mentioned mandrel [1] and time hit baffle ring [4].
By above this cable tool impacter of forecast scheme configuration, mandrel top connection [6] is connected with the top drilling tool; Putting male joint [5] outward is connected with bottom expanding tube reshaping device.Wherein pause and hit baffle ring [4] and under the drilling tool effect of top, can produce upper and lower displacement,, hit in the male joint on the coat [5], make the impulse force that weight produced of top drilling tool pass to the expanding tube reshaping device by moment slip to the lower end from the upper end with mandrel [1].
Claims (1)
1. one kind relates to casing damage well shaping hole enlargement cable tool impacter, forming between end joint [6] and the expanding tube reshaping device under the drilling tool of going into the well, it is characterized in that: prolong joint [6], extension body is the mandrel [1] of band centre bore, outside this mandrel [1], be with overcoat [3], the sliding sleeve [2] of the upper end screw thread adapter sleeve of overcoat [3] on mandrel; The nipple [5] of the lower end screw thread connecting band centre bore of overcoat [3], this joint is connected with the expanding tube reshaping device; Be threaded in the lower end of mandrel [1] and time hit baffle ring [4].
