Control of borehole trajectory: The liquid crystal stabilizer mainly plays the role of pointing and righting in the drilling tool assembly. The installation position of the liquid crystal stabilizer controls the inclination angle and the borehole curvature within the specified range, and also makes most of the weight of the drill collar Concentrate on the drill bit to reduce the non-borehole center force and other external forces on the drill string and the drill bit. With the development of liquid crystal stabilizers and the exploitation of a large number of horizontal and directional wells, liquid crystal stabilizers have become an indispensable bottom hole drilling tool in modern borehole trajectory control technology.
Reaming function: It is drilled along with the drill string at the curved borehole or the borehole shrinkage, and the chamfer at the transition between the lower end body and the working section plays a certain role of reaming.
Resting the well wall: as the liquid crystal stabilizer is in frictional contact with the well wall, it has different degrees of trimming effect on the well wall, making the well wall smoother and smoother and improving the quality of the well.
