Description
Technical field
The utility model belongs to cased servicing unit in the oil drilling casing job, particularly telescopic wiper seal provisions for grouting.
Background technology
In the oil drilling casing job,, need in the short as far as possible time, all sleeve pipes have been descended in order to make casing safety apace down to projected depth.Generally speaking, following 10 to 20 sleeve pipes are irritated once slurry.But when under sleeve pipe, arriving certain depth, because the effect of sleeve pipe bottom single current valve, bunch tube can produce certain buoyancy, slows down the sleeve pipe downstream rate, prolong the cased time, in addition, owing to stop mud grouting for a long time, be easy to generate sticking card phenomenon, be that sleeve pipe is bonded on the borehole wall, transfer difficulty, cause the cutting ferrule pipe, make under the sleeve pipe not in place.
Summary of the invention
The purpose of this utility model is to provide a kind of telescopic wiper seal provisions for grouting, can make that construction operation does not stop in the whole setting of casing process, shortens the setting of casing time, in filling process, can eliminate the buoyancy that produces in the sleeve pipe automatically, good seal performance.
The purpose of this utility model is achieved in that a kind of telescopic wiper seal provisions for grouting, on the end face of cylindrical shell sealing suspension ring are being set, the lower end of cylindrical shell is provided with necking, on its sidewall, mud entrance is being set, the interior pipe of in cylindrical shell, installing, its upper end has sealing flange, the anchor ring of sealing flange and cylinder inboard wall are movingly, stretch out on the tube wall of interior pipe of cylindrical shell necking steam vent is being set, between interior seal of tube flange in cylindrical shell and the cylindrical shell necking inwall compression spring is installed, its upper end of bushing pipe that is positioned at pipe is fixed in the pipe upper end to have on the door of centre bore, centre bore is communicated with bushing pipe, annular floating drum is installed on the outer wall of bushing pipe, the external diameter of floating drum and the internal diameter of interior pipe are movingly, the internal diameter of floating drum cooperates with the crest clearance of bushing pipe, the reducing plunger that is connected by spring controlled pull bar is installed in liner at its lower end, the pull bar bottom guide holder interior with being fixed in bushing pipe matches, the small end diameter of plunger of reducing plunger matches with the internal diameter of bushing pipe, its big end plug diameter matches with the internal diameter of interior pipe, the length of little end plug gets length greater than big end plug, and the flowing hole that is provided with on the tube wall of bushing pipe bottom matches with little end plug.
Construction operation does not stop in whole setting of casing process in order to make, and the way of employing is a mud grouting when following every sleeve pipe, promptly at every sleeve pipe make-up, begins mud grouting behind the last button, and sleeve pipe stops mud grouting when transferring to the minimum point turntable surface, connects another root sleeve pipe.The utility model is the special equipment that grouting designs during for following every sleeve pipe, before following every sleeve pipe, by the suspension ring at the utility model top the utility model is hung on hook or earrings earlier, when needs are in the milk, open the valve on the mud entrance, hydraulic pressure in the confession mud line is earlier with the length of spring compressed of installing between interior seal of tube flange in the cylindrical shell and the cylindrical shell necking inwall, the reducing plunger that interior pipe, bushing pipe and lower end are installed stretches out, put in the sleeve pipe and contact the first sealing of formation with sleeve pipe; When pressure continued to increase, the reducing plunger of interior pipe, liner at its lower end was opened, and mud flows in the sleeve pipe, was in the milk, and the air in the sleeve pipe is through up between interior pipe and the bushing pipe, and the steam vent from inner tubal wall is discharged; When air drained, liquid level rose, and promoted the steam vent that the inner tubal wall middle part is blocked in annular floating drum rising, carried out circulation well cleanup.When grouting, when circulation well cleanup finishes, termination of pumping, the pipeline internal pressure returns zero, under the effect of the pull-rod spring of reducing plunger, reducing plunger return, pipe withdrawal original position under the effect of compression spring, making, dripless flows out, and it is clean that surface of the work keeps, and do not influence construction operation.In filling process, the utility model has been eliminated the buoyancy that produces in the sleeve pipe, good seal performance automatically.In whole setting of casing process, the utility model is the special equipment of following every sleeve grouting, adopts the utility model, makes that construction operation does not stop in the whole setting of casing process, has shortened the cased engineering time greatly.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a sectional structure schematic diagram of the present utility model.
The specific embodiment
A kind of telescopic wiper seal provisions for grouting, as shown in drawings, on the end face of cylindrical shell 2 sealings suspension ring 1 are being set, the lower end of cylindrical shell 2 is provided with necking, mud entrance 16 is being set on the sidewall of cylindrical shell 2, the interior pipe of in cylindrical shell 2, installing 3, its upper end has sealing flange, the anchor ring of sealing flange and cylindrical shell 2 inwalls are movingly, stretch out on the tube wall of its middle parts of interior pipe 3 of cylindrical shell 2 neckings and bottom steam vent 6 is being set, 10, compression spring 4 is installed between interior seal of tube flange in cylindrical shell 2 and the cylindrical shell 2 necking inwalls, bushing pipe 5 its upper ends that are positioned at pipe 3 are fixed in pipe 3 upper ends to have on the door of centre bore, centre bore is communicated with bushing pipe 5, annular floating drum 7 is installed on the outer wall of bushing pipe 5, the internal diameter of the external diameter of floating drum 7 and interior pipe 5 movingly, the internal diameter of floating drum 7 cooperates with the crest clearance of bushing pipe 5, the reducing plunger that is connected by spring controlled pull bar 8 is installed in bushing pipe 5 lower ends, match with guide holder 9 in being fixed in bushing pipe 5 in pull bar 8 bottoms, the centre bore of guide holder 9 and pull bar 8 are being provided with flowing hole movingly around guide holder 9 centre bores.The reducing plunger compound plunger that little end plug and big end plug constitute of serving as reasons, the inside of compound plunger is steel substrate 13, rubber layer 14 at the outer packaging of steel substrate 13, the head of big end plug be a taper shape.Internal diameter in the small end diameter of plunger of reducing plunger and the bushing pipe 5 matches, its big end plug diameter matches with the internal diameter of interior pipe 3, the length of little end plug gets length greater than big end plug, and the flowing hole 15 that is provided with on bushing pipe 5 bottom tube walls matches with little end plug.When the little end plug of the reducing plunger that cooperates with bushing pipe 5 and bushing pipe break away from cooperates before, the big end plug that cooperates with interior pipe 3 cooperates with interior pipe 3 disengagings.Therefore, the air in the sleeve pipe is discharged by the steam vent 6 on interior pipe 3 tops from rising between interior pipe 3 and the bushing pipe 5.Slips sheet 12 by symmetry on the tube wall at steam vent 10 places under the interior pipe 3 is installed with inflatable capsule 11, inflatable capsule 11 is cambered outwards arc surface rubber tube for the middle part has, and the slips sheet 12 of symmetry is pressed abd fixed on the straight tube face at rubber tube two ends on interior pipe 3 walls.When pressure raise, the inflatable capsule of installing on the tube wall at interior pipe 3 lower discharge hole places 11 produced pressure expansion, forms secondary seal between pipe 3 and the sleeve pipe in making.
