Abstract
The utility model provides a sleeve unblocked device. The sleeve unblocked device is characterized by comprising a redressing and obstacle clearing device, a shell, an internal screw shaft, a sleeve adapter and an automatic control device, wherein the redressing and obstacle clearing device and the sleeve adapter are used as a rotor part, the shell, the automatic control device and the internal screw shaft are used as a stator part, one end of the redressing and obstacle clearing device is connected with the sleeve adapter, and a well cementing program and an operation method can not be affected after the sleeve unblocked device provided by the utility model is installed on a sleeve. The sleeve unblocked device provided by the utility model has the functions of automatic force application control, intelligence measurement, redressing and obstacle clearing and the like, a logger can be successfully sent into the bottom part of a well through the functions, the purpose of carrying out well logging from bottom to top can be realized, and the working situation of a certain well section can be analyzed in time.
Description
Technical field
The utility model relates to field, oil field, relates in particular to a kind of power substructure.
Background technology
Oil is important energy source, with coal facies ratio, to have that energy density is large, transportation stores convenient, after burning to advantages such as the degree of contamination of atmosphere are less, the fuel oil refining from oil is the main fuel of vehicle, station boiler, metallurgical industry and the various kilns of building material industry.The liquefied gas that the oil of take is raw material and piped gas be the high-grade fuel of life of urban resident application especially.Oil becomes one of requisite resource in people's life, oil exploitation is the unique channel that obtains oil, in oil exploitation process, the setting of casing problem that each oil field and even the whole world all cannot be avoided that is hampered, for now, solve problem that setting of casing is hampered nothing more than being exactly to pull out sleeve pipe or well cementation on the spot.Pull out sleeve pipe and just mean damage, the delay of time and the increase of cost of sleeve pipe.Although although the frequency that this accident occurs is relatively low, once occur to bring huge economic loss, add heavily to the difficulty of the work, affect exploitation process.
Summary of the invention
According to above technical problem, the utility model provides a kind of sleeve pipe smoothening device, it is characterized in that comprising reaming device for clearing away obstacle, shell, internal helicoid axle, sleeve pipe crossover sub, automaton, described reaming device for clearing away obstacle and sleeve pipe crossover sub are rotor portion, shell, automaton and internal helicoid axle are stationary part, described reaming device for clearing away obstacle one end is connected with sleeve pipe crossover sub, the described sleeve pipe crossover sub other end is connected with shell one end, the described shell other end is connected with internal helicoid axle, described internal helicoid axle other end splicing sleeve, in described shell, be fixed with automaton.
The beneficial effects of the utility model are: when setting of casing, be connected on sleeve pipe bottommost, remove original casing guide, with the utility model, substitute, well solved sleeve pipe in the setting of casing way problem that is hampered, avoid the phenomenon of pulling out sleeve pipe to occur.While being hampered, connect kelly bar circulation reaming, can deal with problems, accomplish under casing 100% once on earth.When cement paste passes through smoothening device, the vibrations of generation, can stir the uneven grain in cement paste, make the dispersed elimination bubble of cement paste.After finishing drilling, carry that just bore can setting of casing and the utility model, without drifting again, simple to operation.After the utility model being installed on sleeve pipe, can't exert an influence to well cementation program and method of operating.The utlity model has automatic control to power, intelligent measure, the reaming function such as remove obstacles, by these functions, the utility model is sent logger into shaft bottom smoothly, realizes well logging object from bottom to top.And can analyze in time the working condition of seeking well section.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
As Fig. 1, reaming device for clearing away obstacle-1, shell-2, internal helicoid axle-3, sleeve pipe crossover sub-4, automaton-5.
The specific embodiment
Shown in Fig. 1, the utility model is further described:
Embodiment 1
During installation, first reaming device for clearing away obstacle 1 one end is connected with sleeve pipe crossover sub 4, then sleeve pipe crossover sub 4 other ends are connected with shell 2 one end, then shell 2 other ends are connected to internal helicoid axle 3, internal helicoid axle 3 other end splicing sleeves, in shell 2, be fixed with automaton 5, reaming device for clearing away obstacle 1 and sleeve pipe crossover sub 4 are rotor portion, and shell 2, automaton 5 and internal helicoid axle 3 are stationary part.
During use, the utility model is connected with sleeve pipe by sleeve pipe crossover sub 4, then guiding sleeve enters well smoothly, after being hampered, reaming device for clearing away obstacle 1 acts on the reaming that can circulate, when cement paste passes through the utility model, internal helicoid axle 3 drives reaming device for clearing away obstacle 1 to produce vibrations, the uneven grain in cement paste can be stirred, and makes the dispersed elimination bubble of cement paste.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
