Description

A kind of Waterpower hydraulic pressure vibrator

Technical field

The utility model relates to a kind of vibrator in the drilling engineering technical field, particularly a kind of Waterpower hydraulic pressure vibrator.

Background technology

The Waterpower hydraulic pressure vibrator is applied in horizontal well inclination section or horizontal segment, backing pressure and frictional resistance are greatly that horizontal well creeps into a difficult problem in the process, the backing pressure problem not only has a strong impact on the rate of penetration of horizontal well, also is very easy to cause the generation of the down-hole complex accident such as sticking card simultaneously.The research of optimizing the technical measures such as well track, pit shaft sliding agent, rigid centralizer has been carried out for problems such as backing pressures in the oil field both at home and abroad, and the horizontal segment frictional resistance is large, the backing pressure problem but above technology can't effectively solve.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the horizontal well that exists in the background technology to creep into backing pressure and the large problem of frictional resistance in the process, and provide a kind of Waterpower hydraulic pressure vibrator, this Waterpower hydraulic pressure vibrator, the pressure of the drill can be applied on the drill bit effectively, reaches the purpose that reduces frictional resistance, prevents backing pressure, improves rate of penetration.

The invention for solving the technical problem can reach by following technical solution: this Waterpower hydraulic pressure vibrator involving vibrations axle and top connection, lower contact, the top connection endoporus is six square sets, top connection and spring are enclosed within vibrating shaft upper end step place from top to bottom, the vibrating shaft of described connection top connection and spring is packed in the body, top connection is threaded with body, body lower end thread connecting joint, the joint lower end connects lower body, in the lower body stator is housed, rotor, rotor is packed in the stator, rotor lower end screw thread universal-joint and upper valve body, the upper valve body lower end is equipped with lower valve body, alignment bearing is inserted on the outer shaft of rotor upper end, the lower contact that is threaded of lower body lower end, and lower valve body is packed in the hole of lower contact.

The utility model is compared with the above-mentioned background technology can have following beneficial effect: this Waterpower hydraulic pressure vibrator is owing to adopting said structure, axially produce the vibration of the little amplitude of high-frequency at drill string, can reduce the frictional resistance of drill string and the borehole wall, be about to stiction and be transformed into kinetic force of friction, the pressure of the drill can be applied on the drill bit effectively, reaches to reduce frictional resistance, prevent backing pressure, improve rate of penetration.The instrument vibration frequency is high, and vibration is stable, and the Waterpower hydraulic pressure vibrator can be put in down horizontal well inclination section or horizontal segment, the on-the-spot speed-raising successful that uses, satisfy on-the-spot instructions for use, this instrument can with the downhole tool couplings such as LWD, MWD, the well rate of penetration of improving the standard.

Description of drawings:

Accompanying drawing 1 is structural representation of the present utility model.

Among the figure: valve body, 13-lower contact under body, 10-universal joint, 11-upper valve body, the 12-under 1-vibrating shaft, 2-top connection, 3-spring 4-body, 5-joint, 6-alignment bearing, 7-rotor, 8-stator, the 9-.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, this Waterpower hydraulic pressure vibrator involving vibrations axle 1 and top connection 2, lower contact 13, top connection 2 endoporus are six square sets, top connection 2 and spring 3 are enclosed within vibrating shaft 1 upper end step place from top to bottom, the vibrating shaft 1 of connection top connection 2 and spring 3 is packed in the body 4, top connection 2 is threaded with body 4, body 4 lower end thread connecting joints 5, joint 5 lower ends connect lower body 9, in the lower body 9 stator 8 is housed, rotor 7, rotor 7 is packed in the stator 8, rotor 7 lower end screw thread universal-joints 10 and upper valve body 11, upper valve body 11 lower ends are equipped with lower valve body 12, and alignment bearing 5 is inserted on the outer shaft of rotor 7 upper ends, the lower contact 13 that is threaded of lower body 9 lower ends, lower valve body 12 are packed in the hole of lower contact 13.

After the Waterpower hydraulic pressure vibrator is lowered into horizontal segment or inclination section, turn on pump creeps into, drilling fluid is passed through by vibrating shaft 1 endoporus, when flowing through rotor 7 and stator 8, because the variation of the pressure chamber that rotor 7 and stator are 8 makes rotor 7 produce High Rotation Speed, rotor 7 links to each other with upper valve body 11 by universal joint 10, upper valve body 11 High Rotation Speeds, lower valve body 12 is fixed and is not rotated, and upper valve body 11 causes mud flow rate to change with lower valve body 12 relative rotations, thereby produces pressure oscillation, pressure oscillation acts on vibrating shaft 1 lower surface, upper end, when pressure increases, vibrating shaft 1 Compress Spring 3, vibrating shaft 1 is up, when pressure reduces, it is descending that spring 3 promotes vibrating shaft 1, makes vibrating shaft 1 axially reciprocating, and vibrating shaft 1 links to each other with drill string, the drive drill string moves back and forth, and reduces frictional resistance.
