Abstract
The invention relates to a fixed-point sleeve throwing device. The fixed-point sleeve throwing device is characterized in that a final-stage sleeve and a drilling rod are connected to form a sleeve casing assembly through a connecting sleeve, a connector body and a connector; after the device is downwards fed to a preset position in a well following the sleeve, a throwing ball is thrown from a ball throwing position into the connector body, the throwing ball and the inner conical face of the connector body are sealed, a slurry channel is blocked, under high pumping pressure, slurry enters a piston cylinder through a piston cylinder passage on the connector body to drive a piston to move so as to enable the connecting sleeve and the sleeve to be disconnected from the connector body, and therefore the purpose of throwing the sleeve off is achieved.
Description
Technical field
The invention belongs to drilling technology field, relate to a kind of sleeve pipe fixed point and get rid of pipe device.
Background technology
Constructed by orientation horizontal branch hole drilling on ground, seat earth carried out grouting and reinforcing and transforms water-bearing layer, being
Each colliery carries out underground flood damage and administers the most urgent.
By orientation horizontal branch hole drilling construct, seat earth is carried out grouting and reinforcing be colliery underground flood damage is administered one
Plant novel process.In the implementation process of this technique, for ensureing the normal construction of horizontal segment, setting of casing work need to be carried out at inclination section
Industry, so-called sleeve pipe fixed point is a certain segment length that sleeve pipe enters down hole of constructing, non-as two opened on oil, three drive sleeve pipe up to well head
Equally.This just for we have proposed the most lower this section of sleeve pipe and how to get rid of sleeve pipe problem.
Summary of the invention
The technical problem to be solved is to provide one to get rid of pipe device for fixed point setting of casing, is beneficial to drilling technology
Implement.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: by coupling sleeve, joint body, connect
Final stage sleeve pipe and drilling rod are connected into setting of casing combination by head；To behind setting position in well under this device is with sleeve pipe, throw at pitching
Enter pitching in joint body.Wherein, coupling sleeve and joint body matched in clearance, and the piston on joint body is connected in and connects
On head body, joint body is connected with joint screw thread.
Having two piston cylinders on described joint body, piston, in joint body piston cylinder, is connected with coupling sleeve again.
Through hole centered by the described piston on joint body.
The described back-moving spring in joint body upper piston cylinder is little spring, big spring.
Through hole centered by described joint body, inner chamber has a conical surface, conical surface top to have the path towards piston cylinder.
Owing to using technique scheme, the circulation of mud can be implemented during sleeve pipe G.I.H, it is achieved that will
Casing safety ground G.I.H；After arriving under sleeve pipe and specifying well section, by pitching at pitching, pitching is close with joint body inner conical surface
Envelope, slurry channel is blocked, and under high pump pressure, mud enters piston cylinder through joint body upper piston cylinder path, drives piston
Motion, makes coupling sleeve and sleeve pipe depart from joint body and connects, thus reach to get rid of the purpose of sleeve pipe.

Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings:
It is such for being embodied as, and when final stage sleeve pipe arrives well head 10 times, with casing slip, final stage sleeve pipe 10 is supported temporarily
At well head, the pipe device 18 that gets rid of connected by with drilling rod 1 is sling by elevator, is placed on final stage sleeve pipe 10,
Slightly transfer unit head, slowly drive the coupling sleeve 9 getting rid of pipe device 18 to connect in final stage sleeve pipe 10 with rope rotary drill rod 1；
Then unit head 11 is the most descending, and back-up tong 16 clamps drilling rod 1, on the main shaft (protection joint) 15 of unit head 11 is rotatably connected
Drilling rod 1；Proposing casing slip, close pneumatic switch, and tire formula clutch connects, and drives pump to rotate, and mud exports, along height
Pressure pipe remittance 14 entrance main shaft 15 inner chamber, drilling rod 1 inner chamber, joint 2 inner chamber, joint body 4 inner chamber, final stage sleeve pipe 10 inner chambers；
Slowly lowering drill pipes 1 puts well head, and pneumatic switch is closed, and pump stops, and puts well head with drill pipe slip and clamps drilling rod 1, and back-up tong clamps brill
Bar 1, dynamic head main spindle 15 inverts, and under the sleeve combination that enters disengage, then, then connect a drilling rod 1, add chi, until will
The lower appointment position to design of sleeve pipe fixed point, suspends mud circulation.Unit head gooseneck of quickly outwarding winding other for cable pressure cap 12, rise
Go out for cable pressure stifled 13, quickly pitching 3 is put into from there, then blocking for cable pressure stifled 13, screw for cable pressure cap 12；Wait to throw
After ball 3 falls into the inner conical surface of joint body 4, start mud circulation, rigorous concentration pump pressure change, increasing and referring to along with pump pressure
The slight decline of weight table, illustrates that piston 8 is compressed, and final stage sleeve pipe 10 and coupling sleeve 9 have disengaged from joint body 4, above carry
Unit head, if weight indicator does not changes, continuation carries drilling tool, completes to get rid of the complete process process of sleeve pipe.
