Description
One, technical field
The utility model relates to oil exploitation filling anti-sand instrument, fill-type sand preventing tool behind particularly a kind of first back-off.
Two, background technology
Existing oil exploitation filling anti-sand instrument, form by filling tubing string and ball-and-seat structure, generally use first filling during construction, the mode of back back-off is carried out, the structure of this mode and construction exist following shortcoming or deficiency: be ball-and-seat owing to what install on the bilateral body 1., be prone to sand bridge, sand plug in the work progress, sand control pipe is difficult to give up and trips out, and influence is produced; 2. be difficult to anti-flushing well, sand control pipe is not gone out, cause the sand control failure; When 3. transferring flow pack to by squeeze pack, easily that ball, ball seat thorn is bad, make the flow pack failure; 4. because being not closed completely of ball-and-seat, tubing string can not be tested envelope, causing construction to have blindness, and the sand control success rate is low.
Three, summary of the invention
The purpose of this utility model provides fill-type sand preventing tool behind a kind of improved first back-off, adopt bar ball, top valve ball and be contained in the structure that seal is installed on the connecting rod, the mode of filling behind the first back-off of employing in the construction, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art are guaranteed the construction success rate of filling anti-sand.
Fill-type sand preventing tool behind the first back-off described in the utility model comprises and stays the well part and trip out part.The described well that stays partly comprises the pressure ring bottom deblocking fishing head of connection in turn, set pin, lock ring, sheath, the deblocking pin, central tube, sleeve, spacer ring, upper cone, leaf spring, slips, the slips cover, interior helmet, lower cone, sealed joint pipe, last gasket ring, the V-type packing, the lower seal gasket ring, regulate cap, the filling sliding sleeve, sliding sleeve switch, the sliding sleeve switch spring, the spring orientation spool, sealing drum, safety joint, the described part that trips out comprises the steel ball that connection is installed in the top connection in turn, the pin of blocking, hydraulic cylinder, piston, setting ball seat, the connecting rod of giving up, active joint, the filling pipe connector, filling pipe, tubing coupling, the external pipe of bilateral, pipe in the bilateral body, the bar ball, ball seat, shop bolt, the spring positioning cap, the ball-and-seat spring, the spring setscrew nut, communicating pipe, packoff nipple, spring lever, the lower ball base spring, following steel ball and lower ball base, trip out partly to be installed on and stay in the well part, form an integral body.
Wherein, described pressure ring is installed the piston lower end in hydraulic cylinder.Described ball seat is installed on pipe bottom in the bilateral body, is connected with the ball seat bottom in the spring positioning cap, and the spring positioning cap is outer to be connected with communicating pipe.Described bar ball is installed on the ball seat, and its club passes the spring positioning cap, and the club lower end is equipped with ball-and-seat spring and spring setscrew nut.The described top connection and the connecting rod inner chamber of giving up are equipped with setting ball seat.The described connecting rod middle and upper part of giving up is provided with outer step, and seal is installed on it.Described giving up is connected with active joint between connecting rod and the filling pipe.Described active joint comprises the active joint of installing on the filling pipe connector.
The utility model has following advantage compared with prior art:
1, owing on the bilateral body bar ball is installed, sealing is tight, avoids returning on the sand control liquid and causes that sand is heavy, sand card problem.
2, top is equipped with ball valve, prevents to go into the well to set midway.
3, give up and install seal additional on the connecting rod, can carry out tubing string and test envelope, guarantee to set reliable, the tubing string voltage stabilizing, the success rate height does not leak, constructs;
4, between external pipe of bilateral and the sealed joint pipe V-seal structure is installed, makes the tubing string sealing safer reliable.
5, adopt first back-off, the tubular column structure of back filling is tested the back-off of being honored as a queen and is given up, and heavy again seat tubing string prevents the difficult problem that tubing string is blocked, do not go out in location, box top;
But 6 safe ready ground carry out anti-flushing well, and favourable subsequent handling is carried out smoothly.
7, interior pipe connects the form of structure of active joint, and pipe connects the above tubing string rotation of active joint in having only in the time of can guaranteeing back-off, and interior pipe connects active joint not to be changeed with the lower part.
