Abstract
The utility model relates to a sleeve head bowl-slip release control tool which is used in oil-field auger operating process, essentially comprising a rope (1), a pull-ring seat (2), a body (3), a fixing pin (4), and a moving pin (5), which is characterized in that the body (3) is of split structure, the upper end-face is designed with the pull-ring seat (2), the cavity bottom of the body (3) is arranged with longitudinal grooves, the position and quantity of the grooves are corresponding to the position and quantity of guide rods (6) on a sleeve head hanger, the movable pin (5) connects the split portions of the body (3) together. The utility model can operate on a drill floor surface by engaging with the bowl-slip hanger without detaching the blow-out preventer, thereby control and hanging operation on the sleeve at any position is realized. The utility model is simple in structure and convenient for operation.
Description
Technical field
The utility model relates to a kind of in oil field drilling operation process, is used to realize the instrument of controlled release suspension sleeve slips in the casing head, belongs to oil well head device class.
Background technology
In oil drilling (well cementation) operation process, the slip-type hanger of suspension sleeve can be finished suspension operational after all needing to dismantle blowout preventer in the casing head when suspension sleeve, and this will cause, and well head is in no control state in the operating process, brings hidden danger to safety in production.The then requirement of thick oil thermal extraction special cementing technology must have control condition (promptly being with blowout preventer) to construct in the well cementation process, and all can carry out the sleeve pipe suspension operational at an arbitrary position, to guarantee prestressed implementation result.And present existing wellhead assembly and slip-type hanger all can't satisfy the requirement of site operation.
Summary of the invention
For realizing that the band preventer carries out the sleeve pipe suspension operational and guarantees prestressed implementation result, eliminate the potential safety hazard that exists in producing at present, the purpose of this utility model is to provide a kind of casing head slips to discharge control tool, can under the situation of not dismantling preventer, cooperate slip-type hanger in rig floor face operation, realize having control and at an arbitrary position sleeve pipe is carried out suspension operational.
The utility model mainly is made up of rope 1, draw ring seat 2, body 3, steady pin 4, removable pin 5, body 3 is a split type structure, its upper surface design has draw ring seat 2, body 3 intracavity bottoms are processed with longitudinal groove, the position and the number of the guide rod 6 on the position of groove and quantity and the casing head hanger 10 are corresponding, and removable pin 5 links together body 3 subdivision bodies.
The utility model can cooperate slip-type hanger in rig floor face operation under the situation of not dismantling preventer, realize having control and at an arbitrary position sleeve pipe is carried out suspension operational.Has simple in structure, convenience operation.

The specific embodiment
Be described in further detail below in conjunction with 1 pair of the utility model of accompanying drawing.
The utility model mainly is made up of rope 1, draw ring seat 2, body 3, steady pin 4, removable pin 5, body 3 is a split type structure, its upper surface design has draw ring seat 2, body 3 intracavity bottoms are processed with longitudinal groove, the position and the number of the guide rod 6 on the position of groove and quantity and the casing head hanger 10 are corresponding, and removable pin 5 links together body 3 subdivision bodies.Body 3 can adopt tooth embedding split type structure or L shaped step split type structure.
At first slips is controlled the removable pin (5) of releasing tool on rig floor and extracted, the subdivision body of body (3) can be opened for rotating shaft by steady pin (4), body (3) obvolvent after will opening is plugged removable pin (5) then and is locked on sleeve pipe.With the longitudinal groove of body (3) bottom with transfer after the guide rod (6) on the hanger (10) is aimed at, make slips control releasing tool and be sitting on the hanger (10), guide rod (6) just in time is positioned at longitudinal groove and is in the state that does not stress.The casing coupling that utilization is transferred is pressed into body (3) and hanger (10) and body (3) assembly in the casing head, and the other end of rope (1) is stayed on the rig floor face.Upwards lift prestressing force after well cementation finishes, make casing coupling up and leave the certain distance of body (3).When after lifting the stressing operations end, needing to carry out suspension operational, need only carry body (3) on the rope (1) utilizing on the rig floor face, and, make groove and guide rod (6) produce dislocation when the guide rod (6) of hanger (10) makes it rotate an angle after the longitudinal groove of body (3) bottom is thrown off.Unclamp rope (1) body (3) the bump guide rod (6) that hurtles down is cut off stop pin (7), bump subsequently makes that slips (8) is descending to be finished suspension to sleeve pipe and (can clash into repeatedly repeatedly to guarantee cutting off stop pin (7) and the assurance sleeve pipe reliably hangs.
Claims (3)
1, a kind of casing head slips discharges control tool, mainly form by rope (1), draw ring seat (2), body (3), steady pin (4), removable pin (5), it is characterized in that: body (3) is a split type structure, its upper surface design has draw ring seat (2), body (3) intracavity bottom is processed with longitudinal groove, the position and the number of the guide rod (6) on the position of groove and quantity and the casing head hanger (10) are corresponding, and removable pin (5) links together body (3) subdivision body.
2, casing head slips according to claim 1 discharges control tool, it is characterized in that: body (3) adopts tooth embedding split type structure.
3, casing head slips according to claim 1 discharges control tool, it is characterized in that: body (3) adopts L shaped step split type structure.
