Description
Technical field
The present invention relates to a kind of hydraulic rotary guide shoes used in natural petroleum gas field field well cementing process.
Background technique
Traditional guide shoe plays the role of very single in setting of casing, because traditional guide shoe is fixed, and draws
For the outer diameter of shoes as sleeve outer, Frictional Drag of Casing Running is very big, not can solve hole shrinkage problem, cannot improve drilling fluid
Solids-carrying capacity, influences setting of casing speed, or even occurs stuck, leads to not smoothly make cementing quality casing G.I.H
At influence.Chinese invention patent " a kind of rotary guide shoe " (201310568676.6) flows through turbo blade offer due to drilling fluid
Power is small, and the drilling fluid of underground can not be made to form Turbulence Flow to improve the solids-carrying capacity of drilling fluid；Its rotating seat bottom end is in
Cone, the small power in addition in the big upper end in bottom end is small, can be readily intercalated into when encountering long horizontal sections or formation collapse stratum cause it is stuck.
In order to overcome the drawbacks of the prior art and insufficient, the present invention devises a kind of suitable for long horizontal sections and the water of formation collapse situation
Power rotary guide shoe.The guide shoe can reduce Frictional Drag of Casing Running, improve drilling fluid solids-carrying capacity, prevent insert into stratum stuck, solve
The problems such as hole shrinkage, formation collapse.
Summary of the invention
The purpose of the present invention is to provide a kind of hydraulic rotary guide shoes, and the hydraulic rotary guide shoe principle is reliable, structure
Simply, low in cost, Frictional Drag of Casing Running and reaming function can be reduced, had a vast market foreground.
To reach the above technical purpose, the present invention provides following technical scheme.
A kind of hydraulic rotary guide shoe, is made of casing joint, rotary body and conical bearing.
Described sleeve pipe connector is hollow cylinder barrel, and outer diameter is slightly larger than sleeve outer, and there is fluid passage in its underpart, is pushed up
There is internal screw thread at end, and there is reinforcement point in bottom end；Described sleeve pipe connector is connected with rotary body by conical bearing, and conical bearing passes through sealing
Circle is embedded in cylinder barrel bottom；The rotary body is hemisphere, and diameter is slightly larger than sleeve outer, the fluid passage and set of upper part

Two layers of turbine runner provides power to rotary body, and rinses blade and scraper.
Described sleeve pipe connector and casing are connected through a screw thread.
The reinforcement point of described sleeve pipe connector bottom end has 4, is uniformly distributed in casing joint bottom end, which can guarantee
The intensity and integrality of structure in the rotary guide shoe course of work.
There is two layers of turbine runner inside rotary body, the reaction force that drilling fluid high speed is formed when passing through runner drives rotary body
There are helical blade in rotation, rotary body upper surface, and rotary body can be prevented stuck and drive drilling fluid rotation, the arc cone outside rotary body
Shape scraper has 4, is evenly distributed on rotation body side surface, plays the role of reaming and flow-disturbing in setting of casing.
Two layers of turbine runner, the discharge orifice of first layer turbine runner is towards casing string, the drilling fluid that ejects at a high speed
Under the agitation of helical blade, turbulent flow is formed around casing string, is reached and is rinsed borehole wall raising cementing quality and reduce under casing
Enter the effect of resistance；The recess portion between neighboring blades is arranged in the discharge orifice of second layer turbine runner, plays the work of the cleaning edge of a knife
With.
Compared with prior art, the invention has the following advantages:
(1) maximum outside diameter of the rotary body of hydraulic rotary guide shoe is greater than the outer diameter of casing string, so that casing string lower end is not
It is contacted with the borehole wall, reduces Frictional Drag of Casing Running；
(2) hydraulic rotary guide shoe rotary body upper end has helical blade, and blade drives drilling fluid when the rotating body is rotated
Turbulence Flow is formed, the solids-carrying capacity of drilling fluid is improved, reduces Frictional Drag of Casing Running；
(3) hydraulic rotary guide shoe a rotating body is equipped with two layers of runner, and first layer runner, which plays, rinses rotary body upper end
Helical blade provides power to rotary body, prevents rotary body stuck and the effect of disturbance drilling fluid；Second layer runner plays flushing
Scraper edge provides power to rotary body, prevents rotary body stuck and the effect of disturbance drilling fluid；
(4) it is equipped with 4 arc taper-shaped blades outside hydraulic rotary guide shoe rotary body, is evenly distributed on rotation body side surface,
Reaming is played when setting of casing, is streamed and anti-jamming effect.

Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4.
A kind of hydraulic rotary guide shoe is made of casing joint, rotary body and conical bearing 1.During described sleeve pipe connector is
Empty cylinder barrel, outer diameter are slightly larger than sleeve outer, and there is fluid passage in its underpart, and there is internal screw thread 4 on top, and there is reinforcement point in bottom end
5；Described sleeve pipe connector and rotary body are connected by conical bearing 1, and conical bearing is embedded in cylinder barrel bottom by sealing ring 6；It is described
Rotary body is hemisphere, and diameter is slightly larger than sleeve outer, the fluid passage of upper part and the drilling fluid of casing joint lower part
Channel connection, upper surface have helical blade 2, and side has arc taper-shaped blade 3, has two layers of turbine runner inside hemisphere, give
Rotary body provides power, and rinses blade and scraper.
Two layers of turbine runner, the discharge orifice of first layer turbine runner 7 is towards casing string；Second layer turbine runner 8
The recess portion between neighboring blades is arranged in discharge orifice.
The operation principle of the present invention is that: during casing tripping in, stream when drilling fluid enters rotary body by casing joint
Body section reduces, and drilling well flow velocity is accelerated, and the tripping in of casing is convenient in the reaction force increase of casing string axial direction；High speed drilling liquid stream
When through two layers of runner, drilling fluid drives rotary body rotation to the reaction force of runner wall surface, the arc taper-shaped blade on rotary body with
Rotate, realize the function of casing reaming in decentralization process, reduce Frictional Drag of Casing Running, such as formation collapse and contracting
Diameter, it is ensured that casing is smoothly lower to arrive shaft bottom.The discharge orifice of first layer runner is tilted towards casing string direction, plays flushing circular knife
Piece prevents rotary body stuck and disturbance drilling fluid, thus the effect for improving drilling fluid solids-carrying capacity, reducing Frictional Drag of Casing Running；The
The discharge orifice in two laminar flow roads is opened in the recess portion between adjacent arcs taper-shaped blade, plays and rinses the arc taper-shaped blade edge of a knife, prevents from rotating
Body is stuck and disturbs the effect of drilling fluid, reduction Frictional Drag of Casing Running.
