Description
Technical field
The present invention relates to a kind of hydraulic rotary guide shoe used in natural petroleum gas field field well cementing process.
Background technology
Traditional guide shoe plays a part of very single in setting of casing, because traditional guide shoe is fixed, and draws
The external diameter of footwear is as sleeve outer, and Frictional Drag of Casing Running is very big, it is impossible to solve the problems, such as hole shrinkage, it is impossible to improve drilling fluid
Solids-carrying capacity, influence setting of casing speed, or even appearance are stuck, lead to not sleeve pipe G.I.H smoothly, cementing quality is made
Into influence.Chinese invention patent " a kind of rotary guide shoe "（201310568676.6）Because drilling fluid flows through turbo blade offer
Power is small, it is impossible to the drilling fluid formation Turbulence Flow of underground is improved the solids-carrying capacity of drilling fluid；Its rotating seat bottom is in
Cone, the small power in addition in the big upper end in bottom is small, can be readily intercalated into when running into long horizontal sections or formation collapse stratum cause it is stuck.
In order to overcome the defect and deficiency of prior art, 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.
The content of the invention
It is an object of the invention to provide a kind of hydraulic rotary guide shoe, the hydraulic rotary guide shoe principle is reliable, structure
Simply, it is with low cost, Frictional Drag of Casing Running can be reduced, there is reaming function again, with wide market prospects.
To reach above technical purpose, the present invention provides following technical scheme.
A kind of hydraulic rotary guide shoe, is made up of casing joint, rotary body and conical bearing.
Described sleeve pipe joint is hollow cylinder barrel, and its external diameter is slightly larger than sleeve outer, and there is fluid passage its underpart, pushes up
There is internal thread at end, and there is reinforcement point bottom；Described sleeve pipe joint and rotary body are connected by conical bearing, and conical bearing passes through sealing
Circle is embedded in cylinder barrel bottom；The rotary body is hemisphere, and its diameter is slightly larger than sleeve outer, the fluid passage and set on its top
The fluid passage connection of pipe joint bottom, upper surface carries helical blade, sideways with arc taper-shaped blade, had inside hemisphere
Two layers of turbine runner, provides power, and rinse blade and scraper to rotary body.
Described sleeve pipe joint and sleeve pipe are connected through a screw thread.
The reinforcement point of described sleeve pipe joint bottom has 4, is uniformly distributed in casing joint bottom, and the reinforcement point ensure that
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 formed when drilling fluid high speed is by runner drives rotary body
There is helical blade rotation, rotary body upper surface, and rotary body can be prevented stuck and the arc cone outside drilling fluid rotation, rotary body is driven
Shape scraper has 4, is evenly distributed on rotation body side surface, and reaming and flow-disturbing are played a part of in setting of casing.
Two layers of turbine runner, the discharge orifice of first layer turbine runner is towards casing string, the drilling fluid ejected at a high speed
Under the agitation of helical blade, turbulent flow is formed around casing string, reaches that the flushing borehole wall improves cementing quality and reduced under sleeve pipe
Enter the effect of resistance；The discharge orifice of second layer turbine runner is arranged on the recess between neighboring blades, plays the work of the cleaning edge of a knife
With.
Compared with prior art, the invention has the advantages that：
（1）The maximum outside diameter of the rotary body of hydraulic rotary guide shoe be more than casing string external diameter so that casing string lower end not with well
Wall is contacted, and reduces Frictional Drag of Casing Running；
（2）Hydraulic rotary guide shoe rotary body upper end carries helical blade, and blade drives drilling fluid to be formed when the rotating body is rotated
Turbulence Flow, improves the solids-carrying capacity of drilling fluid, reduces Frictional Drag of Casing Running；
（3）Hydraulic rotary guide shoe a rotating body is provided with two layers of runner, and first layer runner plays the spiral for rinsing rotary body upper end
Blade, to rotary body provide power, prevent rotary body stuck and disturbance drilling fluid effect；Second layer runner plays flushing scraper
The edge of a knife, to rotary body provide power, prevent rotary body stuck and disturbance drilling fluid effect；
（4）Provided with 4 arc taper-shaped blades outside hydraulic rotary guide shoe rotary body, rotation body side surface is evenly distributed on, is being trapped
Reaming is played during pipe, is streamed and anti-jamming effect.

Embodiment
The present invention is described in further details below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4.
A kind of hydraulic rotary guide shoe, is made up of casing joint, rotary body and conical bearing 1.During described sleeve pipe joint is
Empty cylinder barrel, its external diameter is slightly larger than sleeve outer, and there is fluid passage its underpart, and there is internal thread 4 on top, and there is reinforcement point bottom
5；Described sleeve pipe joint 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 its diameter is slightly larger than sleeve outer, the fluid passage on its top and the drilling fluid of casing joint bottom
Passage is connected, and upper surface carries helical blade 2, sideways with arc taper-shaped blade 3, has two layers of turbine runner inside hemisphere, gives
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
Discharge orifice is arranged on the recess between neighboring blades.
The present invention operation principle be：During sleeve pipe tripping in, drilling fluid flows when entering rotary body by casing joint
Body section reduces, and drilling well flow velocity is accelerated, and the tripping in of sleeve pipe is easy in the reaction force increase of casing string axial direction；High speed drill well liquid stream
During through two layers of runner, drilling fluid the reaction force of runner wall is driven arc taper-shaped blade on rotary body rotation, rotary body with
And rotate, realize the function of sleeve pipe reaming in decentralization process, reduce Frictional Drag of Casing Running, such as formation collapse and contracting
Footpath, it is ensured that sleeve pipe 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, prevent rotary body stuck and disturbance drilling fluid so that improve drilling fluid solids-carrying capacity, reduce Frictional Drag of Casing Running effect；The
The discharge orifice in two laminar flow roads is opened in the recess between adjacent arcs taper-shaped blade, plays the flushing arc taper-shaped blade edge of a knife, prevents rotation
Body is stuck and disturbs drilling fluid, reduce the effect of Frictional Drag of Casing Running.
