Technical field
The utility model relates to the instrument that oil measurement while drilling, well logging during data in real time are uploaded, and is specifically related to a kind of mud pulse generator.
Background technology
Mud-pulse transmission signal is that the most general, the most reliable and the most stable a kind of method is used in crossing on present oil measurement while drilling, the well logging during data in real time.As shown in Figure 1, in the drilling well 34 of oil reservoir 26, drilling fluid 30 has formed the continuous media on shaft bottom to ground, and this continuous drilling well fluid column becomes desirable signal transmission passage.The signal transmission is that depended on pressure poor (pressure pulse) is realized.The power source that produces pressure pulse is the core component main pump body in the pulser, and the effect of drilling well fluid column is to help the cone valve of impulse generator to reset to minimum point rapidly, prepares the generation of next positive pulse signal.Between impulse generator 28 in the drill string 29 and the inserting tube 27 connecting line 12 is arranged, impulse generator 28 is subjected to the control of inserting tube 27 to produce pressure pulse, the signal of inserting tube 27 being measured by drilling fluid 30 is sent to ground-pressure pick-up 33, pressure sensor 33 is sent to ground instrument 31 with pressure signal by pickup wire 32 again, ground instrument 31 is handled to the received signal, knows the parameter such as hole deviation, orientation, tool-face, temperature of down-hole measuring point.
Three types mud pulse generator is arranged at present, i.e. positive pulse, negative pulse and continuous wave impulse generator, the utility model belongs to positive pulse generator.Electromagnetic valve in the mud positive pulse generator and following instrument all need power supply, and prior art is battery-powered, but the replacing of battery is very inconvenient, and cell voltage is also unstable.
The utility model content
The technical problems to be solved in the utility model provides a kind of mud positive pulse generator, can realize electricity generate function.
In order to solve the problems of the technologies described above, the utility model provides a kind of mud positive pulse generator, comprise the stifled and socket of plunger displacement pump, plunger, plunger displacement pump swash plate, magnetic axis, main valve, end that is installed in the pulser urceolus, be characterized in, also comprise a generator, the rotor that this generator has magnet is connected with the end of described magnetic axis near main valve, and the coil stationary of this generator is on described plug, be provided with at interval with described generator amature, and be electrically connected with described socket.
Further, above-mentioned mud positive pulse generator also can have following characteristics: described generator is a turbogenerator.
Further, above-mentioned mud positive pulse generator also can have following characteristics: the coil of described generator is positioned at the described main valve outside.
Further, above-mentioned mud positive pulse generator also can have following characteristics: the inclination angle of the whole axis of described swash plate and pulser is 8 °～9 °.
Further, above-mentioned mud positive pulse generator also can have following characteristics: the diameter of the suction oil circuit of described plunger is 2～3mm.
As from the foregoing, mud positive pulse generator of the present utility model carries turbine generator, can give self electromagnetic valve and the power supply of following instrument, need not use battery, provide convenience for manipulating, and its supply voltage is more stable than cell voltage.Further, the utility model makes mud positive pulse generator can produce bigger thrust by to the suction oil circuit of pump housing plunger and the design of swashplate angle, is suitable for operation in the deep-well, and has avoided the scratch of swash plate termination.

Fig. 2 is the structural representation that the present embodiment mud positive pulse generator is installed in drill string.
Fig. 3 is the fragmentary detail view of generator among Fig. 2.
The specific embodiment
As shown in Figure 2, be the structural representation that the present embodiment mud positive pulse generator is installed in drill string 1, wherein mud positive pulse generator mainly comprises cone valve 3, guide rod 15, piston 16, plunger displacement pump 5, plunger 6, main valve 17, plunger displacement pump swash plate 18, magnetic axis 19, center oil pipe 9, control valve 10, turbine generator 40, control valve coil 24, end stifled 11 and the socket 25 that is installed in the pulser urceolus 21.Be provided with restrictor ring 2, gasket ring 14 and water conservancy diversion cover 4 between mud positive pulse generator and the drill string, and be socketed with rotor assembly 7 in the outside of magnetic axis 19.Socket 25 receives the control signal of inserting tube by connecting line 12.
During work, drive turbo blade rotor assembly 7 rotation at a high speed from the mud of drill string 1 by restrictor ring 2 centre bores, group of magnets 8 is housed in the rotor assembly 7, on the correspondence position corresponding group of magnets 20 is housed in the magnetic axis 19, rotor assembly 7 drives magnetic axis 19 rotations when rotating, one end and the plunger displacement pump swash plate 18 of magnetic axis 19 are spirally connected, and the rotor 22 of the other end and generator is spirally connected.Swash plate 18 drives plunger displacement pump 5 when rotating plunger 6 replaces back and forth, realizes the work of plunger displacement pump.
Generally, control valve 10 is in open mode, and fluid is let out from main chamber toward the side chamber, and plunger displacement pump 5 is in Light Condition.When electromagnetic valve 24 drives generation magnetic force closed control valve 10 by signal, the cavity of piston 16 produces pressure and promotes piston 16 and guide rod 15 drive cone valves 3 upwards close restrictor rings 2, thereby make drilling fluid form a surge pressure wave, compression wave is upwards propagated the pressure sensor until the face of land.This compression wave can effectively carry signal, thereby realizes underground signal wireless transmission earthward.
In order to be adapted to operation in darker well, the inclination angle of the whole axis of the utility model swash plate and pulser is 8 °～9 °, as 8 ° 30 ', promote plunger with its axial spacing and produce pump housing pressure source, the inclination angle increases, and the plunger pump delivery also increases thereupon, can produce bigger thrust, even in darker well, also can operate as normal.After ring scratch easily on the termination of existing swash plate and the bearing, the utility model were adjusted the inclination angle of swash plate, above-mentioned phenomenon had been eliminated in evidence.In addition, the suction oil circuit overstriking of the utility model pump housing plunger, diameter is 2～3mm, and the driving force of the pump housing is strengthened, pulse is stronger, transmits rapider.
In order to realize electricity generate function, present embodiment is provided with the turbogenerator of being made up of generator amature 22 and generator coil 23 40, shown in the fragmentary detail view of Fig. 3, generator amature 22 includes magnet, it is screwed onto the end of magnetic axis 19 near main valve 10,23 outsides that are socketed in main valve 10 of generator coil, and be fixed on the end stifled 11, and a little distance is arranged between the generator amature 22.When magnetic axis 19 rotates, also rotation thereupon of the magnet on its terminal generator amature 22 that connects, generator coil 23 cutting magnetic lines produce induced electromotive force, form the three-phase high-frequency alternating current.And be transferred to socket 25 by circuit, export again for the pulser electromagnetic valve and below inserting tube use.
