Abstract
The utility model relates to the technical field of oilfield drilling tools, in particular to a one-trip drilling tool for a directional well, which comprises a drill bit, a single curved screw body centralizer, a single curved screw, a short drill collar, a centralizer, a non-magnetic drill collar and an MWD wireless inclinometer while drilling, wherein the drill bit, the single curved screw body centralizer, the single curved screw, the short drill collar, the centralizer and the non-magnetic drill collar are sequentially and fixedly arranged together from bottom to top, and the MWD wireless inclinometer while drilling is fixedly arranged in the non-magnetic drill collar. The one-trip drilling tool for the directional well is reasonable and compact in structure, and convenient to use, and can realize one-trip drilling engineering of a straight well section-a directional section-a stable inclined section, thus greatly enhancing drilling speed, shortening drilling cycle, and having good inclining prevention effect.
Description
Technical field
The utility model relates to oil field drilling tool technical field, is brill drilling tool of a kind of directional well.
Background technology
Along with deepening continuously of oil field prospecting exploitation, directional well drilling is not subjected to the supremacy clause of the influence of topography and geomorphology with its output height, and quantity constantly increases.Directional well drilling is divided into straight well section-three sections constructions of orientation section-steady tilted section usually, need multiple trips to switch drilling tool structure, especially in the bigger stratum construction of stratigraphic dip, the control of straight well section wellbore quality is strict, and the anti-oblique effect of common pendulum assembly is undesirable.Therefore exist rate of penetration slow, the problem that drilling period is long.
Summary of the invention
The utility model provides a kind of directional well a brill drilling tool, has overcome the deficiency of above-mentioned prior art, and it can effectively solve directional well drilling needs multiple trips to switch the problem of drilling tool structure.
The technical solution of the utility model realizes by following measure: brill drilling tool of a kind of directional well, comprise drill bit, single curved screw rod body centralizer, single curved screw rod, stub boring quickly, centralizer, non magnetic drill collar and MWD wireless drilling inclinometers; Drill bit, single curved screw rod body centralizer, single curved screw rod, stub boring are quickly, centralizer and non magnetic drill collar be fixedly installed togather from bottom to top in regular turn, are installed with the MWD wireless drilling inclinometers in non magnetic drill collar.
Be further optimization and/or improvements below to above-mentioned utility model technical scheme:
The center of above-mentioned drill bit can be between 0.8 meter to 0.9 meter to the distance of single curved screw rod body centralizer mid point.
The center of above-mentioned drill bit can be 0.84 meter to the distance of single curved screw rod body centralizer mid point.
Distance between curved screw rod body centralizer mid point of above-mentioned list and the centralizer mid point can be between 12 meters to 13 meters.
Above-mentioned drill bit, single curved screw rod body centralizer, single curved screw rod, stub boring are quickly, centralizer and non magnetic drill collar can be fixedly installed togather by screw thread from bottom to top in regular turn.
The utility model reasonable and compact in structure, easy to use, it can realize driller's journey of straight well section-orientation section-steady tilted section, has therefore greatly improved drilling speed, has shortened drilling period, and anti-tiltedly effective.
