Abstract
The utility model relates to the technical field of petroleum well cementation, in particular to an inner-clamping type top-driving casing pipe running device which is matched with a top-driving well drilling device or a well-drilling power swivel in use. The inner-clamping type top-driving casing pipe running device comprises an upper central pipe and a lower central pipe, which are connected with each other, wherein a reset oil cylinder, a drive oil cylinder, a drive mechanism, a slip mechanism, a leather cup type sealer and a guiding cone are arranged on the upper central pipe and the lower central pipe from top to bottom in sequence. According to the utility model, after blockage happens, a pump can be started at any time to circulate slurry without configuration of a pair of casing pipe tongs and special grouting equipment, so that the operation safety is enhanced and the operation cost is reduced; in addition, the defect that the slurry cannot be circulated in time when a casing pipe is blocked or gets stuck during running in the prior art is overcome.
Description
Technical field:
The utility model relates to a kind of oil cementing technology field, and the setting of casing device is driven on particularly a kind of inner blocking type top that is used with top-drive drilling or drilling well power swivel.
Background technology:
According to the requirement of oil drilling technology, after accomplishing, each drillng operation all to carry out corresponding setting of casing, well cementing operation.Purpose is the packing stratum, reinforces the borehole wall.Conventional setting of casing equipment mainly comprises slips, the casing tong that is used for the splicing sleeve screw thread, the open mud grouting device that is used for interrupted mud grouting that are used for fixing casing string, be used to other aids such as make-up sheath of promoting the casing elevator of whole casing string and being used for the protective sleeve pipe thread.
Cased flow process is: it is single to well head to promote sleeve pipe with elevator, with well head sleeve pipe make-up, uses hydraulic casing tongs rotation top single connection of sleeve pipe; On carry casing string, unclamp stationary slip, transfer casing string to well head; Lay stationary slip, open casing elevator, on request grout injection between the casing string and the borehole wall; Accomplish a sleeve pipe G.I.H, the above flow process that circulates is up to the whole G.I.Hs of required sleeve pipe.
When adopting the conventional tool setting of casing, hole quality can influence cased process, and timely circulating mud when being hampered, meeting card is in the time of seriously even cause work accident.
The utility model content:
The technical problem that the utility model will solve provides a kind of inner blocking type top and drives the setting of casing device, and this device has been realized need not to dispose casing tong and special grouting equipment, and turn on pump circulating mud at any time after being hampered improves operational security, reduces operating cost.Overcome existing setting of casing and be hampered, met the timely deficiency of circulating mud of when card.
The technical scheme that the utility model is taked is: the setting of casing device is driven on a kind of inner blocking type top, comprises upper center tube and lower center tube; Upper center tube is connected with lower center tube, and drawback cylinder, driving oil cylinder, driving mechanism, slips mechanism, the sealing of leather cup formula and leading cone are installed on upper center tube and lower center tube from top to bottom successively.
The beneficial effect of the utility model is: the utility model can be given full play to the superiority of top-drive drilling or drilling well power swivel, need not to dispose casing tong and special grouting equipment after being used, and drilling well troop can carry out casing job voluntarily; At any time turn on pump circulating mud after being hampered improves operational security, reduces the operating personnel, improves operating efficiency, reduces operating cost.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Accompanying drawing is the structural representation of the utility model.
The specific embodiment:
Shown in accompanying drawing, the setting of casing device is driven on a kind of inner blocking type top, comprises upper center tube 1 and lower center tube 5; Upper center tube 1 is connected with lower center tube 5, and drawback cylinder 2, driving oil cylinder 3, driving mechanism 4, slips mechanism 6, the sealing 7 of leather cup formula and leading cone 8 are installed on upper center tube 1 and lower center tube 5 from top to bottom successively.
In the utility model when work,, hydraulic oil gets into driving oil cylinder 3 backs and promotes driving mechanisms 4 and move downward, and drives slips mechanism 6 and moves downward along the inclined-plane and open, tighten internal surface of sleeve pipe.On carry the back under the effect of sleeve pipe load formation self-locking.Can carry out put-on and delegated, the rotary operation of sleeve pipe this moment.Operation fixes sleeve pipe after accomplishing, and hydraulic oil gets into drawback cylinder 2 and accomplishes homing action, and slips mechanism 6 loosens, and waits for next instruction.
It is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
