Background
The fish finding tool for the bent pipe has a drilling and milling function, and cannot be used for processing the condition that the fish top is broken and irregular and hard sundries are near the fish top. In addition, the success rate of finding fish in the oil-water well with large breakpoint staggering amplitude is low.
Disclosure of Invention
The utility model provides a fish milling shoes instrument is looked for to elongated post awl structure collarband to solve the problem of mentioning in the above-mentioned background art.
In order to solve the technical problem, the utility model provides a following technical scheme:
the fish finding and milling tool with the pilot hole of the lengthened column-cone structure comprises an upper joint, a conical milling shoe and a cylindrical milling shoe, wherein the upper joint is connected with a wide head of the conical milling shoe, a narrow head of the conical milling shoe is connected with one end of the cylindrical milling shoe, and the conical milling shoe and the cylindrical milling shoe are provided with straight-through type water holes which are communicated.
As an optimized technical proposal of the utility model, the conical milling shoe comprises a conical body and an alloy
Blocks, water holes, and many alloy blocks are welded on the surface of the cone.
As an optimized technical scheme of the utility model, the welding of alloy piece range order is on the toper body surface.
As an optimized technical scheme of the utility model, the cylindricality mill shoe comprises cylindricality body, alloy piece, water hole, and a lot of alloy pieces welding are on the cylindricality body surface.
As an optimized technical scheme of the utility model, the welding of alloy piece range order is on the cylindricality surface.
As an optimized technical proposal of the utility model, the alloy block is a hard alloy block.
As an optimized technical scheme of the utility model, the hydrophthalmia of toper mill shoe is the same with the hydrophthalmia diameter of post type mill shoe, and meets the position and coincide completely.
During the operation construction, will the utility model discloses add elongated column cone structure pilot and look for fish milling shoes instrument's top connection and connect in screw rod drilling tool motor output shaft nipple lower part, then along with near oil pipe comes down the breakpoint. And starting a pump to flush the fish top, performing milling repair on the damaged part of the fish top, guiding a fish finding tool to enter a lower fish falling cavity to complete fish finding, then performing drilling and sweeping flushing treatment along the original well track to reach an artificial well bottom, and finally performing cementing to realize circular well sealing.
The utility model discloses the beneficial effect who reaches is: the utility model relates to an elongated column-cone structure pilot hole fish finding and milling tool, which is designed for solving the problems of casing dislocation, stratum collapse and the like in an oil field, the best application state is that the broken fish top of the casing is not completely lost, mud rock is spitted from the stratum at the dislocation part, the return amount is not very large, and especially the broken point is not standard or the broken point has more sundries, the effect is more outstanding, the elongated column-cone structure pilot hole fish finding and milling tool of the utility model has the advantages that the upper joint is connected with the screw head of the motor output shaft of a screw drill, the lower part is aligned with the construction part of the broken point fish top, the screw drill power motor is connected with the conventional oil pipe, the tool does not need to lift the pipe column after entering a cavity, the continuous addition of a single oil pipe is realized, the secondary loss of the fish top after the cavity entering tool is lifted up is avoided, the functions and the functions of guiding, drilling, milling and repairing, reliable application, convenient carrying, low cost and strong operability.
