Abstract
The invention relates to a petroleum hollow drill rod convenient for scrap guide. The hollow drill rod comprises a cylindrical main rod body, wherein a through hole is formed in the main rod body; a column sleeves the outer wall of the main rod body; the outer wall of the column is provided with a plurality of grooves; a groove I is cooperatively formed in each groove; the diameters of cross sections of the grooves I and the grooves are the same; the distance of openings in the top ends of the grooves I is less than the diameter of the cross sections of the grooves I; all the grooves I protrude out of the grooves in both the axial direction and the transverse direction; the lower parts of the grooves I are provided with annular baffle plates; the annular baffle plates are provided with scrap accommodating grooves in the axial direction of the grooves I. By forming the grooves I with the scrap guide and fixation functions, waste scraps produced during drilling can be excellently collected and fixed, and the problem of blockage in a well due to incapability of scrap discharge of the existing drill rod is solved.
Description
Technical field
The present invention relates to field of petroleum machinery, particularly, relate to a kind of oil hollow drill being convenient to dust lead.
Background technology
hollow drill is when degree of depth drilling well, the drilling well excretas such as a lot of soil bits, aggregate chips and mud can be produced in well, if these chip removal things can not be discharged in time, well, excreta in well can be caused to pile up, blocking in well is not only to the destruction that drill bit, drilling rod etc. cause, but also there will be the problems such as drill bit is stuck, drilling rod can not move, not only destruction caused to rig but also have impact on the operating efficiency of rig, being unfavorable for practicality and development.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of oil hollow drill being convenient to dust lead, chip removal can not cause the problem that blocks in well to overcome existing drilling rod.
The present invention's adopted technical scheme that solves the problem is: the oil hollow drill being convenient to dust lead, comprise columniform main rod body, through hole is offered in main rod body, main rod body outer wall is arranged with cylinder, cylinder outer wall offers multiple groove, groove I is equipped with in each groove, groove I is identical with the diameter of the cross section of groove, the distance of the opening on groove I top is less than the diameter of groove I cross section, groove I is in axis, laterally all protrude from groove, the bottom of groove I is provided with ring baffle, ring baffle is axially provided with chip pocket in groove I.Cylinder the stability strengthening hollow drill is set, be convenient to arrange groove I on drilling rod, arranging on the one hand because it is in axis of groove I, laterally all protrude from groove, groove I is made to carry out second time drilling well, improve smoothness and the planeness of the borehole wall, Reinforcing Shaft, on the other hand, the soil bits that groove I produces when can collect drilling well, some scrap of aggregate chips etc., the scrap being can not block drilling well, guarantee carrying out smoothly of drilling well, simultaneously, ring baffle is provided with in groove I, this ring baffle and groove I have identical radian, and be provided with chip pocket in ring baffle, ring baffle and chip pocket with the use of can well the scrap collected is fixed in groove I, improve effect and the stability of groove I dust lead, the present invention is by arranging the groove I having dust lead and admittedly consider function to be worth doing, the scrap produced when can be good at collection and fixing drilling well, overcome existing drilling rod and chip removal can not cause the interior problem blocked of well.
Further, one end that main rod body coordinates with ring baffle is provided with locating shaft, and described through hole runs through locating shaft.Oil drill rocker locating shaft when connecting, by oil drill rocker and connector location, prevents oil drill rocker from occurring tilting, ensures the guidance quality of oil drill rocker and connector.
Further, the length of locating shaft is 60-80mm.Locating shaft mainly plays well location and a guide effect when connecting, consider the problem of locating shaft location and guiding intensity and material, the length of locating shaft is set to 60-80mm, while minimal material, strengthens its location and guiding intensity in use.
Further, groove I is evenly provided with 6.Groove I offers the structural stability having influence on cylinder too much, and dust lead effect is bad very little, and 6 groove I derive the scrap in well simultaneously, while guaranteeing cylinder stability, improve operating efficiency.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is by arranging the groove I having dust lead and admittedly consider function to be worth doing, the scrap produced when can be good at collection and fixing drilling well, and overcoming existing drilling rod chip removal can not cause the interior problem blocked of well.
2, the present invention is by arranging locating shaft, ensures the guidance quality of oil drill rocker and connector.
