When there is hole shrinkage due to geological formations problem, the piece that subsides, because rig underpower or well track restriction are can not rotary sleeve pipe string time, use traditional casing appliances to be easily lowered to be obstructed and even cannot use.The indoor design of novel spinning casing appliances has unique driving mechanism, can under the condition of low discharge capacity, low pump pressure, rely on internal flow driven tool spinning work, the in the situation that of rotary sleeve tubing string not, its guiding is lowered to; And the broken rock reaming of the Drill bit that can utilize instrument bizet, stabilizing borehole, guarantees casing safety, is lowered into design attitude efficiently; Treat to design attitude post-infusion cement slurry, to cement the well under sleeve pipe, after by the time theing cement solidifies, with junk bit, can within tens minutes, drill tool string, whole operation economical and efficient.
Utility model content
The purpose of this utility model is in order to solve the Casing running technology difficult problem in other Holes of Complicated Wells body structure well cementing operations such as horizontal well, deep-well, ultradeep well, improves well cementation efficiency and quality, reduces the cost and risk of shaft building.Carried especially a kind of brill, expansion, solid integrated setting of casing power traction device.
For achieving the above object, the technical scheme in the invention for solving the above technical problem is: a kind of brill, expansion, solid integrated setting of casing power traction device mainly comprise turbine shroud, turbine back-up ring, fastening bolt, turbine rotor, turbine stator, air deflector, sleeve, bearings housing, deep groove ball bearing group and tractor bizet.Its architectural feature is: in turbine shroud, fixed two ends by the multistage turbine stator of turbine shroud and sleeve compression; Multistage turbine two ends of rotor is by turbine back-up ring and air deflector compresses and air deflector is fixed together; On air deflector, have pod apertures; Air deflector lower end is connected with tractor bizet; Tractor is fixed on bearings housing by deep groove ball bearing group, and bearings housing is threaded connection with turbine shroud and links together; On tractor bizet, there is into the stupefied of 15 ° ~ 30 ° of lead angles, stud with hard-metal insert on stupefied; On tractor bizet, have circumferential hydrophthalmia, dorsal part hydrophthalmia, axial hydrophthalmia.
Described tractor bizet asymmetrical shape can be designed to lozenges and become the wedge shape wedge shape cylindric or that lozenges is arc of 30 ° cylindric; At its inclined-plane dorsal part, have the dorsal part hydrophthalmia of 1 ~ 3 30 ° ~ 45 °, at inclined-plane axial direction, have an axial hydrophthalmia, circumferentially having a circumferential hydrophthalmia; On tractor bizet, there is lead angle to become 15 ° ~ 30 ° stupefied, stud with hard-metal insert on stupefied.
The beneficial effects of the utility model are: (1) can overcome due to the restriction of rig underpower or well track problem that can not rotary sleeve pipe string; (2) this instrument provides power to carry out reaming by efficient down-hole motor, does not need the drifting operation just can be by sleeve pipe once down to design attitude; (3) internal drive motor adopts the material manufacture of drillable, can under the condition of low discharge capacity and low pump pressure, work, under sleeve pipe to cementing well after design attitude, waiting to have cemented the well to the cement solidifies can drill from inside whole tool string with junk bit afterwards within tens minutes, then opened inferior wellbore construction under continuing.Use the utility model instrument work progress fast, economy, success rate is high.
