Abstract
The utility model relates to a kind of high angle hole, horizontal well setting of casing instrument, and particularly one rotates reaming formula guide shoe.The reaming lower body part external surface of this device is inlaid with Talide, reaming main body lower end inner wall connects spool, rotating eccentricity top guide upper end also can rotate freely through spool in spool, and rotating eccentricity top guide upper end outer wall connects pressure cap, and pressure cap is articulated on spool.The utility model achieves and ensures that high angle hole and horizontal well casing pipe are transferred smoothly to design attitude, and reduce the resistance that sleeve pipe is transferred, use procedure is convenient and safe.Overcome existing casing guide to be hampered in high angle hole and horizontal well casing job process, cause sleeve pipe can not transfer deficiency to design attitude.
Description
Technical field:
The utility model relates to a kind of high angle hole, horizontal well setting of casing instrument, and particularly one rotates reaming formula guide shoe.
Background technology:
At present, conventional casing guide structure is generally made up of dome-type (or taper) guide shoe head and housing, and be mainly used in preventing mouth at the bottom of sleeve pipe from touching and scrape or insert the borehole wall, guiding sleeve is smoothly down to shaft bottom.
Continually develop utilization along with petroleum gas, turn to deep layer, Complicated as reservoir gradually, the exploitation of ocean conventional gas and oil utilizes.Drilling crew is also faced with the technical problem of the Holes of Complicated Wells such as deep-well, high angle hole, horizontal well, wherein just there is darker high angle hole, technological difficulties that horizontal well casing pipe is transferred.Conventional casing guide often occurs that the problem be hampered transferred by sleeve pipe in high angle hole and horizontal well casing job process, causes sleeve pipe not transfer to design attitude smoothly.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of rotation reaming formula guide shoe, and the arrangement achieves and ensure that high angle hole and horizontal well casing pipe are transferred smoothly to design attitude, reduce the resistance that sleeve pipe is transferred, use procedure is convenient and safe.Overcome existing casing guide to be hampered in high angle hole and horizontal well casing job process, cause sleeve pipe can not transfer deficiency to design attitude.
Technical solution adopted in the utility model is: a kind of rotation reaming formula guide shoe, comprises reaming main body; Reaming lower body part external surface is inlaid with Talide, reaming main body lower end inner wall connects spool, rotating eccentricity top guide upper end also can rotate freely through spool in spool, and rotating eccentricity top guide upper end outer wall connects pressure cap, and pressure cap is articulated on spool.
The beneficial effects of the utility model are: the utility model ensures that high angle hole and horizontal well casing pipe are transferred smoothly to design attitude, and reduce the resistance that sleeve pipe is transferred, use procedure is convenient and safe.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is external surface schematic diagram of the present utility model.
Detailed description of the invention:
As shown in Figure 1 and Figure 2, a kind of rotation reaming formula guide shoe, comprises reaming main body 1; Reaming main body 1 lower external face is inlaid with Talide, reaming main body 1 lower end inner wall connects spool 3, rotating eccentricity top guide 4 upper end also can rotate freely through spool 3 in spool 3, there is gap between rotating eccentricity top guide 4 and spool 3 can rotate freely, maybe can design bearing and rotate freely; Rotating eccentricity top guide 4 upper end outer wall connects pressure cap 2, and pressure cap 2 is articulated on spool 3.
Because the spinfunction of rotating eccentricity top guide 4 makes the guiding incline of rotating eccentricity top guide 4 against well track all the time in sleeve pipe decentralization process, reduce the resistance that sleeve pipe is transferred.If be hampered, can carry out rotation casing job, the Talide in reaming main body 1 can eliminate obstacle in well, ensures to enter to design attitude under sleeve pipe smoothly.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
