Abstract
The invention relates to a tubular column lowering power tractor with a well grinding and repairing function, wherein the tubular column lowering power tractor is used for the oil and gas cement job. According to the technical scheme, a screw motor is used as a driving mechanism; a motor rotor and the crown portion of the tractor are connected together through a transmission shaft and a fluid director; a flow guide hole is formed in the fluid director, and water holes are formed in the crown portion of the tractor to drain drilling fluid. Hard alloy teeth are inlaid on the crown portion of the tractor. The tubular column lowering power tractor with the well grinding and repairing function can guide and lower a sleeve in under the condition that the sleeve column is not rotated, the crown portion of the tractor can break rock and broaden a hole, and the tractor ensures that the sleeve can be lowered into a designed position safely and efficiently. The rotatable and asymmetrical crown portion of the tractor has strong capacity for crossing ledge barriers in a well, after the sleeve is lowered into the designed position, a tool can be drilled with a milling bit in about a dozen minutes, and then cement is injected in to fix the well. The tubular column lowering power tractor with the well grinding and repairing function can provide an output torque which is large enough, and can be used even under the working conditions when the well conditions are very complex.

Technical field
The present invention relates to the lower tubular column power traction device that a kind of oil, gas drilling are used, particularly a kind of lower tubular column power traction device with mill well workover eye function.
Background technology
It is common technical barrier in the well cementing operations such as horizontal well, high angle hole that setting of casing is hampered, and eccentric guide shoe commonly used comes at the bottom of the guiding sleeve lower going-into-well.But be subjected to hole anomaly, step, the impact of the piece that subsides etc., even use eccentric guide shoe often to occur also that setting of casing is hampered, sticking card, even be lowered to the problem that unsuccessfully waits, thereby cause construction period and construction cost all significantly to rise.
When because hole shrinkage appears in the geological formations problem, the piece that subsides, because the restriction of rig underpower or well track can not the revoling tube string time, be used traditional casing appliances easily to be lowered to be obstructed even can't be used.The indoor design of novel spinning casing appliances has unique driving mechanism, can rely on internal flow driven tool spinning work under the condition of low discharge capacity, low pump pressure, in the situation that the rotary sleeve tubing string is not lowered to its guiding; And the broken rock reaming of the Drill bit that can utilize the instrument bizet, stabilizing borehole guarantees casing safety, is lowered into design attitude efficiently; Until behind design attitude, can within tens minutes, drilling tool string with junk bit under the sleeve pipe, then begin cementing well, whole operation economical and efficient.
Summary of the invention
The objective of the invention is to improve well cementation efficient and quality 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, reduce the shaft building cost and risk.A kind of lower tubular column power traction device with mill well workover eye function is provided especially.
For achieving the above object, the present invention addresses the above problem the technical scheme that adopts and is: a kind of lower tubular column power traction device with mill well workover eye function mainly comprises screw motor stator housing, rubber bushing, motor rotor, power transmission shaft, air deflector, bearings housing, deep groove ball bearing group and tractor bizet.Its architectural feature is: adopt motor as driving mechanism, it is comprised of screw motor stator, rubber bushing and motor rotor, and the motor rotor upper end is unsettled, and the lower end links to each other with power transmission shaft; Power transmission shaft links together motor rotor and air deflector upper end, has pod apertures on the air deflector; Air deflector lower end and tractor bizet link together; Tractor bizet asymmetrical shape can be designed to lozenges according to well, and to become the cylindric or lozenges of 30 ° wedge shape be that the wedge shape of arc is cylindric; The tractor bizet has 1 ~ 3 30 ° ~ 45 ° dorsal part hydrophthalmia at the inclined-plane dorsal part, have vertically 1 axial hydrophthalmia in the inclined-plane side, is circumferentially having 1 circumferential hydrophthalmia, to discharge mud; The tractor bizet studs with hard-metal insert.
The invention has the beneficial effects as follows: (1) can overcome because the restriction of rig underpower or well track and problem that can not the revoling tube string; (2) this instrument provides power to carry out reaming by efficient down-hole motor, does not need the drifting operation just can be with sleeve pipe once down to design attitude; (3) internal drive motor adopts the manufacturing of drillable material, can under low discharge capacity and low pump pressure condition, work, can drill internally whole tool string with junk bit in reaming within tens minutes to target depth, work progress fast, economy, success rate is high.
