Abstract
The utility model relates to a drifting and milling combination tool belonging to the technical field of the drifting and milling combination tool for oil field workover operation. The drifting and milling combination tool comprises a main body and milling shoes, wherein, an upper connector of the main body is connected with a running string, the milling shoes are welded on the lower end surface of the main body, and an anti-clipping well cleaning water tank is arranged on the wall of an outer tube of the main body. The utility model can finish the two working procedures of drifting and milling at one time during the workover operation, reduces the construction cycle as well as the labor intensity of the workers, and saves the operating cost.
Description
Technical field:
The utility model relates to a kind of drifting cover and mills combination tool, belongs to the oil well repairing operation drifting, overlaps the combination tool technical field of milling.
Background technology:
In the underground work construction, drifting operation and cover miller preface are separately carried out, and employed downhole tool is also different, and the drift size gauge tool that the former uses belongs to the detection type workover tool, the latter uses casing section mill to belong to brill, grinds, mills class, because the design feature of the two restriction generally can not be used with.During routine work, after drifting was hampered, according to the degree of depth and the hole condition data of being hampered, the miller preface might be overlapped by the side.Like this, mill, cause the underground work operation to increase when drifting is hampered to trip out that changing traps again and mill jacket casing midway, the job execution cycle stretch-out, operating cost increases, and also influences the ordinary production of oil-water well.
Summary of the invention:
The purpose of this utility model is the defective that overcomes above-mentioned prior art, provides a kind of and not only can detect latus rectum in the sleeve pipe and whether meet standard but also can be rotated and creep into that cover mills internal surface of sleeve pipe foul, incrustation scale, the drifting cover washed towards salt, sand washing, heat mills combination tool.
The utility model is made up of body, milling shoe, and the top connection of body and running string connect, and are welded with milling shoe on the lower surface, have anti-sticking well-flushing tank on the body outer tube wall.
When adopting the utility model to carry out workover treatment, can once finish drifting, overlap and mill two procedures, shorten construction period, alleviate working strength of workers, save operating cost.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
As shown in Figure 1: the utility model is made up of body 1, milling shoe 3, and the top connection of body 1 and running string connect, and are welded with milling shoe 3 on the lower surface, have anti-sticking well-flushing tank 2 on body 1 outer tube wall.
When carrying out workover operation construction, body 1 top connection and running string are connect and G.I.H, when if body 1 is hampered, the rotation tubing string, the milling shoe 3 of its lower surface is under the pressure of the drill effect, wedging also grinds foul, and fouls such as oarse-grained sand, salt block return out ground by the anti-sticking well-flushing tank 2 on body 1 outer tube wall.
