Background technology：
Oil gas water well conventional completed well is seated on well head big four using boll-weevil hanger connected pipes, and well head big four makes
It is connected with casing head with casing nipple.In process of production well control is required in well head seepage, or operation process, need to implement to change
Shaft mouth operation, after removing well head, well is in runaway condition.To ensure well control safety, tradition is changed shaft mouth operation and is first pressed
Well, acts tubing string in well, then dismantles old well head, more renews well head.There is problems with this mode for changing well head：1st, kill-job
Liquid is missed, and causes reservoir pollution, causes reservoir possible permanent damage.2nd, flow chart is complicated, long construction period, increases labour intensity
And operating expenses.
The content of the invention：
The purpose of this utility model is to overcome prior art because working procedure is complicated, pollution reservoir, long construction period, cost
A kind of high problem, there is provided cutting ferrule sealer for changing well head.
Cutting ferrule sealer of the present utility model, by component and black box is set and solid lower contact is constituted, sets component
Constituted by body, drive link, wedge shape sliding sleeve, slips, slip spider, spring, spacing ring is set, it is tubular structure to set body, if
There is stepped central through hole, upper end is threadedly coupled with the central tube of black box, and lower end is threadedly coupled with solid lower contact, thereon
Bar shaped slip groove is evenly equipped with portion's outer tube wall；Drive link is inverted " t " character form structure, is inserted into and sets in body and black box
In the central through hole of heart pipe；Up big and down small wedge shape sliding sleeve is threadably mounted on drive link；Slip spider is concave structure, is passed through
Its lower end central through hole is sleeved on drive link, is fixed by spacing ring, and its internal diameter is opened more than the external diameter of drive link on its outer tube wall
There is the longitudinal bar shaped sliding groove corresponding with the slip groove set on body outer tube wall；Slips is " H " shape structure, is inserted into slips
In longitudinal bar shaped sliding groove of seat, on the inside of the slip spider and slips between annular space in adjustable spring is installed；Black box by
Central tube, packing element, spacer ring and compression cylinder composition, packing element is sleeved on the outer shoulder in central tube middle part, and compression cylinder is threadably mounted at glue
On the central tube on cylinder top.
The binding site tapering transition section of slips and wedge shape sliding sleeve.
Described black box is made up of central tube, packing element, spacer ring and compression cylinder, and packing element is sleeved on central tube middle part between outer land
On shoulder, compression cylinder is threadably mounted on the central tube on packing element top.
The packing element of described black box is at least two grades, and every grade of packing element is separated by spacer ring.
Effect of the present utility model is to realize that OIH pipe hangs by setting component, and by black box sleeve pipe is realized
Sealing, makes well in safe control condition, reaches no killing well, does not play the purpose that tubing string in well changes well head, shortens the activity duration,
Operating expenses is reduced, reservoir pollution and construction cost is reduced.
Description of the drawings：
Fig. 1 is structural representation of the present utility model.
Specific embodiment：
The utility model is further illustrated with reference to the accompanying drawings and examples.
Referring to the drawings 1, cutting ferrule sealer of the present utility model, by setting component 1 and black box 2 and solid lower contact 3
