Production Description:
Drilling tool stabilizer is a device that keeps the slender drill pipe running smoothly when the drill pipe string rotates at high speed in the hole, so that the axis of the drill bit is as close as possible to the center line of the drilling hole, also called centralizer. The stabilizing function is mainly to reduce the violent vibration of the drill pipe string elastic system in the radial and axial directions in the hole, to reduce the eccentric wear of the drill bit and the drill pipe, to ensure the coring quality, to prevent the well deviation or artificial directional drilling. The structure of the stabilizer is relatively simple, which is a thick-diameter joint with rib pieces (straight or spiral).
Drilling tool stabilizer is an important tool to prevent the change of well deviation in oil, gas and geological exploration drilling engineering. The form of the stabilizer can be divided into drill string type and bottom hole type.
Product Advantages:
Control the wellbore trajectory: the stabilizer mainly plays the role of pointing and righting in the drilling tool assembly. The installation position of the stabilizer controls the well inclination and the curvature of the wellbore within the specified range, and also makes most of the weight of the drill collar concentrated in the drill collar. On the drill bit, reduce the non-borehole center force and other external forces on the drill string and the drill bit. With the development of stabilizers and the massive production of horizontal and directional wells, stabilizers have become an indispensable bottom hole tool in modern wellbore trajectory control technology.
Reaming effect: in the curved wellbore or the diameter of the wellbore, it is drilled with the drill string, and the chamfer at the transition between the lower body and the working section plays a certain role in reaming.
Shaping the well wall: During the frictional contact between the stabilizer and the well wall, it has different degrees of dressing effect on the well wall, making the well wall smoother and smoother and improving the quality of the well body.
