Abstract
The utility model relates to a measurement while drilling apparatus for the well drilling of an oil field, in particular to a guiding shoe lockout device for a keyseat sticking type measurement while drilling apparatus. According to the guiding shoe lockout device, a screw hole is formed in a positioning joint; a hole is formed at the position corresponding to the screw hole of the positioning joint on a circulating sleeve; a jack screw cap is arranged at the upper end of a jack screw, external threads are arranged outside the middle of the jack screw, and a pin nail is arranged at the lower end of the jack screw; and the jack screw is screwed in the screw hole of the positioning joint, the lower end of the jack screw penetrates through the hole of the circulating sleeve, and the bottom of the jack screw jacks in anti-trip groove of a guiding shoe. By the guiding shoe lockout device, the axial vibration of the measurement while drilling apparatus is avoided, key-escaping accidents are prevented, and the defects of high possibility of axial vibration and even key escaping of the conventional measurement while drilling apparatus during construction are overcome.
Description
Technical field:
The utility model relates to a kind of oil drilling measurement while-drilling instrument, particularly a kind of seat key formula steering tool guide shoe locking device.
Background technology:
At present, directional well and horizontal well have become the important channel of efficient development of fields.Sitting key formula steering tool is the real-time monitoring tool of a kind of advanced well track that generally adopts in current directional well and the horizontal well drilling industry.Existing some the no anticreep key of key formula steering tool instrument string of sitting designs, and some adopts the anticreep key design of the guide shoe of circulation cover+anticreep groove of being with spring, steel ball, and these instrument strings are in the practice of construction process; When drilling or switch pump; Under the high-pressure slurry effect, all make instrument produce strong axial vibrations easily even take off key, be prone to cause instrument damage even can't operate as normal; Increase drilling period, increase cost of drilling engineering.
The utility model content:
The technical problem that the utility model will solve provides a kind of seat key formula steering tool guide shoe locking device, and this device has realized preventing the steering tool axial vibrations, anti-anti-avulsion key accident.Overcome the deficiency that existing steering tool is prone to the generation axial vibrations even takes off key in construction.
The technical scheme that the utility model is taked is: a kind of seat key formula steering tool guide shoe locking device, comprise landing nipple, circulation cover and guide shoe, and circulation is placed in the landing nipple, and guide shoe places in the circulation cover; Have screw on the landing nipple, circulation puts the position perforate of corresponding landing nipple screw, and the jackscrew upper end is designed to the jackscrew cap, and the outside, middle part is designed with external screw thread, and the lower end is designed to pin; Jackscrew is screwed in the screw of landing nipple, and the hole that circulation puts is passed in the lower end, and the bottom withstands in the anticreep groove of guide shoe.
The jackscrew cap outer wall of jackscrew upper end is provided with groove, and O-ring seals is installed in the groove.
The beneficial effect of the utility model is: the utility model puts the mode that jackscrew locking guide shoe is installed owing to having adopted in landing nipple and circulation, thereby has the function that prevents the steering tool axial vibrations, prevents anti-avulsion key accident.
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, a kind of seat key formula steering tool guide shoe locking device comprises landing nipple 1, circulation cover 2 and guide shoe 4, and circulation cover 2 places in the landing nipple 1, and guide shoe 4 places in the circulation cover 2; Have screw on the landing nipple 1, the position perforate of corresponding landing nipple 1 screw on the circulation cover 2, jackscrew 3 upper ends are designed to the jackscrew cap, and the outside, middle part is designed with external screw thread, and the lower end is designed to pin; Jackscrew 3 is screwed in the screw of landing nipple 1, and the hole on the circulation cover 2 is passed in the lower end, and the bottom withstands in the anticreep groove of guide shoe 4.The jackscrew cap outer wall of jackscrew 3 upper ends is provided with groove, and O-ring seals is installed in the groove.
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.
