Abstract
The invention relates to a gyroscopic-effect well drilling speed-increasing tool in the field of petroleum drilling. The tool is mainly characterized in that an upper joint, a drill collar pup joint and a lower joint are sequentially connected from top to bottom through screw threads to form a tool shell; bearing pairs are arranged at the upper end and the lower end of a central gyrorotor inside the tool; the two bearing pairs are arranged in an upper bearing pedestal and a lower bearing pedestal respectively; the upper bearing pedestal and the lower bearing pedestal are fixed into a concave ring groove of the drill collar pup joint; bearing pedestal end covers are arranged at the upper end of the upper bearing pedestal and the lower end of the lower bearing pedestal; a turbine stator is arranged at the lower end of the upper bearing pedestal, and is in screwed connection and fixed with the upper bearing pedestal; a turbine rotor is arranged on the large-diameter upper end of the gyrorotor and is in screwed connection and fixed with the gyrorotor; and sealing rings are arranged at the lower end of the upper joint and the upper end of the lower joint for being sealed with the drill collar pup joint. According to the gyroscopic-effect well drilling speed-increasing tool, due to the fact that the vibration and the reciprocating motion do not exist, accidents such as tool fatigue and damage or leakage are avoided, and therefore the tool is safe.
Description
Technical field
The invention belongs to the instrument increasing drilling machinery drilling speed in a kind of the drilling well speedup instrument, particularly a kind of drilling process of field of oil drilling.
Background technology
Drilling tool is in drilling process, and the mechanical property that lithology inhomogeneities and drilling tool due to stratum rotate makes drill bit not poly-middle rotary drilling in shaft bottom, but sweeps thorax and beat rotary drilling.Such result makes drilling machinery drilling speed reduce, and drill bit utilization rate reduces, and causes drilling cost to increase.In order to effectively improve drilling machinery drilling speed, people have invented mechanical type and hydraulic type vibratory instrument, to increase drill bit to the cutting dynamics of rock stratum and frequency, increase rate of penetration; Also have simultaneously and adopt spring or fluid pressure type vibration dampening tool, try hard to reduce and sweep thorax and beat, to improve rate of penetration caused by bit bounce.This kind of instrument is owing to adopting vibration and moving back and forth, and instrument self exists mechanical fatigue and seal failure problem, and serious meeting causes the accident of creeping into.
Summary of the invention
In order to solve the deficiency that background technology exists, the invention provides a kind of gyroscopic effect drilling well speedup instrument.The present invention is according to gyro approximation theory, namely when the rotating speed of gyrorotor in instrument be far longer than drill bit sweep the rotating speed of thorax and beat time, this gyrorotor can regard as gyro, and it has gyroscopic effect; When in drilling process, the instrument stub boring that the motoricity that drill bit sweeps thorax and beat generation can be installed by nearly drill bit quickly passes to gyrorotor through bearing, according to gyroscopic effect, generation reaction force goes to offset the motoricity that drill bit sweeps thorax and beat generation by gyrorotor, creep into pressure holding state in making drill bit maintenance poly-, so just can effectively improve drilling machinery speed.Because there is not vibration and moving back and forth in gyroscopic effect drilling well speedup instrument of the present invention, therefore instrument self is very safe.
The technical solution used in the present invention is: a kind of gyroscopic effect drilling well speedup instrument, top connection, drill collar pipe nipple and lower contact from top to bottom order screw thread are connected to form tool outer casing, the upper and lower side of tool interior center gyrorotor is all equipped with bearing pair, two bearing pairs are placed in top chock and step respectively, the outer upper end of top chock contacts with gasket ring, lower end, outside contacts with turbine spacer, they fix by the concave ring groove that formed with top connection lower end of topping bar of drill collar pipe nipple, the outer upper end of step contacts with guiding cover, lower end, outside contacts with gasket ring, they fix by the concave ring groove that formed with lower contact upper end of getting out of a predicament or an embarrassing situation of drill collar pipe nipple, the upper end of top chock and the lower end of step are all mounted with bearing cover, turbine stator is arranged on top chock lower end, and fix with top chock screwed connection, turbine rotor is arranged on the large through upper end of gyrorotor, and fix with gyrorotor screwed connection, the lower end of top connection and lower contact upper end are equipped with sealing ring and are used for sealing with drill collar pipe nipple.In drillng operation, when drilling fluid flows through instrument, drilling liquid flow kinetic energy can be converted to the rotational of the High Rotation Speed of gyrorotor by turbine rotor, thus produces gyroscopic effect.Wherein bearing pair is combined by arc raceway ball bearing group to be assembled.In addition, this instrument of two or more can be connected in series when an instrument speedup effect is undesirable and carry out wellbore construction operation.
The invention has the beneficial effects as follows: the present invention goes to offset the motoricity that drill bit sweeps thorax and beat generation due to the gyroscopic effect of employing gyrorotor, creeps into, so just can effectively improve drilling machinery speed in making drill bit maintenance poly-with pressure holding state.And because there is not vibration and move back and forth in gyroscopic effect drilling well speedup instrument of the present invention, so there will not be the accidents such as instrument fatigue failure or leakage, therefore instrument self is very safe.
