Description
Technical field
The present invention relates to technical field of petroleum extraction, particularly relate to a kind of drill bit the pressure of the drill that effectively increases in the exploitation of the complex structural well such as high angle hole, horizontal well to improve the drilling water forced oscillation device of rate of penetration.
Background technology
Current known hydroscillator is using singe screw as vibration power motor.Due to single-screw rotor High Rotation Speed in stator, cause the packing element life-span in stator greatly to shorten, the thorn that comes unstuck bad phenomenon, can not meet on-the-spot needs.
Summary of the invention
The object of the invention is to solve existing hydroscillator singe screw oscillating motor short for application life, the problems such as stator processing difficulty is large, a kind of turbine oscillator simplifying oscillator structure, improve application life is provided.
The object of the present invention is achieved like this: turbine oscillator, comprise be threaded successively from the bottom to top lower contact, urceolus, top connection, connect lower disc seat at the upper end internal thread of described lower contact, the upper end of lower disc seat arranges lower disc, lower disc is arranged semicircular arc lower disc hole; In described urceolus, rotor mandrel is set, the lower end diameter of rotor mandrel is greater than upper end diameter, in the lower end of rotor mandrel, axially blind hole is set, valve block seat on blind hole internal thread connects, valve block on the lower end of upper valve block seat connects, upper valve block is arranged valve block hole on semicircular arc, upper valve block correspondence is arranged on the top of lower disc; Between the upper end and urceolus of described rotor mandrel, arrange turbine stator and turbine rotor, turbine stator is fixed on the inwall of urceolus by stator retaining ring, and turbine rotor is fixed in rotor mandrel by locking nut; Form ring cavity between rotor mandrel below described turbine rotor and urceolus, rotor mandrel arranges axle through hole, ring cavity is connected with the blind hole of rotor mandrel by axle through hole.
Operating principle of the present invention: in drilling process, cement paste, through turbine stator water conservancy diversion impact rotor blade, makes turbine rotor High Rotation Speed, and rotor driven mandrel rotates, and then band moving valve plate rotates.Because lower disc maintains static, therefore valve block through hole is for a moment overlapping, closes for a moment, i.e. the descending ascending mechanical periodicity again of flow channel area.The sectional area (maximum value and minimum value) that periodic relative motion causes fluid to flow through instrument periodically changes.
When valve block hole is in minimum, fluid is minimum by the sectional area of instrument, by the Pressure Drop that after instrument, just generation one is maximum; When valve block hole is in maximum, fluid is maximum by the sectional area of instrument, so the pressure drop produced is minimum; The mechanical periodicity that sectional area cyclically-varying causes upstream pressure synchronous.
Due to little time large during pressure, the downward thrust produced in drilling tool also with regard to time large time little, simultaneously under the elastic reaction of drilling tool, cause other drilling tool is connected with instrument to produce reciprocating motion in the axial direction, formed and vibrate.Make the drilling tool static friction temporary transient in shaft bottom become dynamic friction, reduce frictional resistance, so instrument effectively can reduce the drilling tool produced because of well track draw phenomenon, periodically pressurization is produced to its underpart drilling tool simultaneously, realize fast drilling.
The present invention has following characteristics:
1. structure is simple, and the life-span is long, stable performance.
2. change the pressuring method of drill bit.The pressurization of simple mechanical type is changed into the pressuring method that combines with fluid power of machinery, for drill bit provide truly, effective the pressure of the drill;
3. avoid false the pressure of the drill and drilling tool buckling phenomenon occur when high angle hole section is crept into, elimination high angle hole, horizontal well are subject to the impact of drilling tool partical gravity, buoyancy and frictional resistance, obtain true, stable the pressure of the drill;
4. reduce frictional resistance, prevent backing pressure.Oscillator makes its upper and lower drilling tool produce longitudinal reciprocating motion in well in drilling process, drilling tool is made to become dynamic friction in the static friction of down-hole, greatly reduce frictional resistance, instrument can reduce the drilling tool backing pressure phenomenon produced because of well track effectively, ensures effective the pressure of the drill.
