球形稳定器：球形稳定器结构短小紧凑、钻井阻力小，适用于打水平井及定向井。主要用于大斜度或水平井的钻井工程中，是控制井斜变化的重要工具。合理使用球形钻具稳定器，能有效地防止卡钻事故地发生，提高井深质量和钻井速度，降低钻井成本。
Spherical Stabilizer
Spherical Stabilizer is an important tool to control hole deviation when drilling a horizontal well or a
deflecting well. The stabilizer can prevent from stucking in drilling and improve the quality of well and
speed of drilling,which decrease the cost of drilling. Because of ***all size, simple structure, it is so
applicable for horizontal and directional well .The guide inclined plane covered with polycrystalline
compact and cutting edges covered with spherical tungsten carbide stud ,during stabilizer contacts
with roughed hole wall , can cut or scraped off raised or irregular well wall, therefore, the spherical
stabilizers are widely used in various of drilling operation.
