Abstract
The invention discloses a kind of from grouting type variable float collar float shoe device, including shell, valve seat, back-pressure valve, support set, orifice plate, pressing sleeve, copper ball, spring, pedestal.Of the invention a kind of from type variable float collar float shoe device is in the milk in casing job, inside pipe casing ring is logical, it is no longer necessary to which well head worker grouting, mud reach internal and external pressure balance by sleeve bottom sleeve pipe.When carrying out circulation scouring operation, mud enters from after grouting type variable float collar float shoe device, and mud is continuously increased, and pressure is continuously increased, and pressure finally acts on pressing sleeve, and pressing sleeve is mobile, and copper ball is rolled out from ball, so that back-pressure valve moves up, clogs valve seat through-hole.
Description
Technical field
The invention belongs to cementing equipment technical fields, more particularly to a kind of grouting type variable float collar float shoe device certainly.
Background technique
Float collar float plug is the required tool in well cementing operation.The quality of float collar float plug, directly affects cementing quality.Often at present
The valve of the well cementation float collar float plug of rule, the inside installation is mostly a kind of check valve, generally all not no effects of self-priming, therefore provides one kind
Automatic grouting can be realized in operation, can improve working efficiency, more secure and reliable, novel product technology easy to operate.Casing
After transferring to setting position, when carrying out circulation scouring operation, mud pushes pressing sleeve, rolls out copper ball.After operation is washed away in completion, return
Pressure valve automatic touch closes automatic grouting channel to valve seat.It is more more convenient than conventional well cementation, more securely and reliably.
Summary of the invention
The present invention solves the technical problem of: aiming at the problem that existing float collar float plug does not have self-priming effect, provide
A kind of more secure and reliable from grouting type variable float collar float shoe device, operation difficulty can be made to reduce, improve work efficiency, save at
This, environment is clean and tidy, safety in production.
To achieve the goals above, the technical scheme is to design a kind of from grouting type variable float collar float shoe device,
Including shell, valve seat, back-pressure valve, support set, orifice plate, pressing sleeve, copper ball, spring, pedestal；The shell is tubular；The valve seat is set
It sets in the intracorporal middle and upper part of shell；Through-hole is equipped in the middle part of the valve seat；Portion's inner wall in the housing is arranged in the support set, and is located at valve seat
Lower section；The orifice plate is arranged below support set；It is cylindrical sleeve structure, the cylindrical sleeve in the middle part of orifice plate in the middle part of the orifice plate
The orifice plate of structure two sides is equipped with orifice plate through-hole；The pressure is set below orifice plate, sets pressing sleeve through-hole, the hole in the middle part of pressing sleeve
Cylindrical sleeve structure in the middle part of plate passes through pressing sleeve through-hole；The back-pressure valve top is the plug-like knot for blocking valve seat middle through-hole
Structure, middle part is cylindrical-shaped structure, and the cylindrical-shaped structure at middle part passes through the cylindrical sleeve structure in the middle part of orifice plate, and pedestal is arranged in hole
The bottom of cylindrical sleeve structure in the middle part of plate；Cylindrical-shaped structure side wall in the middle part of the back-pressure valve and the cylindrical sleeve in the middle part of orifice plate
Ball is set in shape structure side wall, ball is embedded in copper ball, and the pressing sleeve through hole wall of pressing sleeve pushes down copper ball；The spring one end connection
The plug-like structure on back-pressure valve top, the other end connect pedestal.
Further, the valve seat is threadedly attached in shell.
Further, the shell upper and lower side is equipped with pin thread or female thread for connecting sleeve.
The advantages and beneficial effects of the present invention are: a kind of type variable float collar float shoe device of grouting certainly of the present invention is in setting of casing
When operation, inside pipe casing ring is logical, it is no longer necessary to which well head worker grouting, mud reach interior external pressure by sleeve bottom sleeve pipe
Dynamic balance.When carrying out washing away cycle operation, mud enters from after grouting type variable float collar float shoe device, and mud is continuously increased,
Pressure is continuously increased, and pressure finally acts on pressing sleeve, and pressing sleeve is mobile, and copper ball is rolled out from ball, so that back-pressure valve moves up, plug
Firmly valve seat through-hole.
