The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The utility model mainly is made up of body 13, plunger 11, central tube 12 and controlling organization etc., setting upright of body 13 has several holes on the rib, plunger 11 is installed in the hole, upper end surface at control joint 1 is equipped with differential pressure pickup 2, in the annular groove at its middle part drive motors 3, intelligent control unit and electrokinetic cell 4 is installed; Driven wheel 5 is installed on the motor output shaft that its underpart end face stretches out to be meshed with the driven gear ring that control is overlapped on 6; The bottom design of control cover 6 has uniform boss (quantity of boss should greater than 2 integer), supports and be positioned the upper surface of locating ring 8 by ball; The upper design of thrust piston 9 endoporus has and the control cover corresponding boss of 6 lower boss (quantity, size are all identical), and it adopts plug-in type to be connected with central tube 12, by black box 14 realization sealings between the two; And between the interior step of the bottom of central tube 12 and body 13 bottoms back-moving spring 15 is housed, differential pressure pickup 2 corresponding positions are drilled with intercommunicating pore on body 13 and control joint 1, and be connected with annular space, be processed with dovetail groove on the cylindrical of central tube 12, and the hole of opening on the rib with setting upright of body 13 is corresponding, and the bottom of plunger 11 is processed with measure-alike trapezoid boss; The bottom design of control cover 6 has raceway, and identical raceway has also been designed in the upper surface of corresponding locating ring 8, is placed with the ball of some between the two; The upper design of control cover 6 has driven gear ring; Design has a guide peg on the lower surface of locating ring 8, matches with the pilot hole of thrust piston 9.
Store the coding of the multiple duty of variable gauge stabilizer in the intelligent control unit.Before instrument is gone into the well at first on rig floor by slush pump being left-termination of pumping operation, with the pressure pulse code signal that sends, check the control of variable gauge stabilizer reducing whether working properly, only just often can go into the well at tool work.The original state of variable gauge stabilizer is set to minor diameter, promptly the corresponding boss of boss and thrust piston 9 endoporus tops of control cover 6 bottoms is aligned with each other, this moment control cover 6 will be placed restrictions on thrust piston 9 and be promoted 10 times enforcements of central tube plunger 11 stretch out under the effect of mud pressure reduction, make stabilizer be locked in the minor diameter state.When needs are adjusted to the major diameter duty with variable gauge stabilizer, can by open-termination of pumping operation sends a pressure pulse code signal, be transferred to intelligent control unit 4 after detecting by differential pressure pickup 2, the output control instruction is handled drive motors 3 rotations after identification is judged, the driven gear ring rotation that is driven on the control cover 6 by driven wheel 5 makes control cover 6 rotating certain angle, the corresponding boss of boss and thrust piston 9 endoporus tops of control this moment cover bottom staggers mutually, control cover 6 will not placed restrictions on its motion, thrust piston 9 promotes 10 times enforcements of central tube plunger and stretches out under the effect of mud pressure reduction, thereby makes stabilizer become the major diameter duty up to termination of pumping once more.Termination of pumping rear center pipe 10 is exercised plunger 11 withdrawals under the promotion of back-moving spring 15 once more, and stabilizer turns back to initial minor diameter duty again.If the value that the termination of pumping time surpass to be set, then again behind the turn on pump stabilizer will continue maintenance major diameter duty.Change back the minor diameter duty if desired, only need carry out termination of pumping operation and termination of pumping time above the value of setting, intelligent control unit detect and judge this pulse signal after will send control instruction, handle drive motors 3 rotations, make control cover 6 rotating certain angle once more, the boss of control this moment cover bottom aligns once more mutually with the corresponding boss in thrust piston 9 endoporus tops, control cover 6 recovers the motion of thrust piston 9 is placed restrictions on, and variable gauge stabilizer is reset to the minor diameter state.The general pump operated change that can not cause tool state of start-stop in drilling process.
