Abstract
The utility model relates to a top driving device for sleeve well drilling which is suitable to be used for surface sleeve well drilling. Based on the prior top driving system, the technical proposal of the utility model is that the top driving system is connected with the screw thread of the short segment of the drill rod; the integrated slip of the sleeve well drilling driving device and the taper sealed leather bowl are both inserted into a sleeve; the external diameter of the slip is larger than the internal diameter of the sleeve; the slip is supported on the inner wall of the sleeve; the slip is joggled with a taper body when a main body steering keying and the taper body steering keying are in the same quadrant with a slip steering groove; the top driving system drives the taper body to move upwards; the slip is expanded by taper body; the slip tooth seizes the inner wall of the sleeve; a protective sleeve lock locks the sleeve coupling to prevent the slip from rolling out; the top driving system lifts and rotates the sleeve through the driving device; and transmits the torsion moment so as to achieve sleeve well drilling. When the driving device is lifted upwards, the top driving device rotates rightwards for 1/4 circle; the main body steering keying and the taper body steering keying are reversed with the slip steering groove; the slip and the taper are no longer joggled with each other; and the top driving device moves upwards and lifts the slip from the sleeve.
Description
Technical field
The utility model relates to a kind of casing drilling top-drive device, mainly is applicable to the surface pipe drilling well, belongs to the oil drilling machine field.
Technical background
At present, the type of drive of external casing drilling adopts top-drive device more, and is easy to control, quick, reliability is high, but costs an arm and a leg.Up to now, domestic also do not have a casing drilling top-drive device, and casing drilling only adopts rotating disk to drive usually, by sleeve pipe driver transfer torque,
Summary of the invention
The purpose of this utility model is to provide a kind of casing drilling top-drive device, and promptly this device can utilize existing top to drive drive unit system and implement casing drilling.
The technical solution adopted in the utility model is as follows; be a kind of casing drilling with top-drive device from top to bottom successively by drill pipe nipple; cone; leather cup constitutes; it is characterized in that rib-loop is connected between drill pipe nipple and cone; cone is certain gradient; the angle that is cone generatrices and top-drive device axis is between 10 ~ 45 degree; there are cone reversing key and body reversing key in the surface of cone; slips has the commutation groove; slips and protective sleeve are assembled together; lock ring is equipped with in the protective sleeve lower end; slips and protective sleeve parts are by the slips groove that commutates; cone commutation groove and body commutation groove are sleeved on the cone, with swivel nut above-mentioned sunk key changement are fixed.Leather cup is installed in the bottom of cone.
Operating principle of the present utility model is the screw thread of top drill pipe nipple and being threaded of TDS with this device; rely on the monolithic slips of TDS with the casing drilling drive assembly; cooperate cone and sealing cup together to be inserted in the sleeve pipe; the slips external diameter is a bit larger tham casing inner diameter; slips is supported on the internal surface of sleeve pipe; body reversing key and cone reversing key and slips commutation groove are at same quadrant; ensure the engagement of slips and cone; it is descending that TDS drives cone; cone forces the slips expansion; watt tooth is bitten internal surface of sleeve pipe; the protective sleeve lock ring pins casing coupling; prevent that slips from skidding off; with sleeve pipe lifting and rotation and transfer torque, sealing cup plays reverse sealing by circulating pressure to TDS by driver at this moment, realizes that sleeve pipe creeps into.If the proposition driver, this moment, top-drive device drove driver 1/4 circle of turning right, and body reversing key and cone reversing key commutate with the dislocation of slips commutation groove, and slips and cone can not mesh, and was about to the slips of driver on the top-drive device put forward in sleeve pipe.
The utility model has been realized domestic TDS casing drilling, and simple operations is convenient, seal reliable convenient disassembly, sleeve pipe is difficult for skidding, damaging, long service life.
