变向器是用于定向钻井的新型井下工具,它有特殊的结构设计,可有效地用常规转盘钻井纠正方位角,或用于克服地层漂移力取得定向钻井的稳方位钻进。新工具在辽河油田进行了多次现场试验,平均可得1.5°/30米的“扭方位”效果。
Inverters are new downhole tools for directional drilling. They have a special structural design that can effectively correct azimuths with conventional turntables or to achieve steady-state drilling for directional drilling over strata drift forces. New tools in the Liaohe Oilfield conducted a number of field trials, an average of 1.5 ° / 30 meters of “torsional orientation” effect.
