摘　　要：钻井过程中影响井斜的因素很多,井斜是钻井工程中比较普遍的现象,其直接影响着钻井井身质量和钻井速度,并造成巨大经济损失。复合钻井防斜打快技术不仅可以在直井钻进中实现防斜打快目的,而且可以实现定向井轨迹的连续控制,并且大幅提高钻井速度,减少起下钻次数。复合钻井防斜打快技术在地层倾角大的地方具有广阔的应用前景。Many factors affecting borehole deviation in well drilling, and borehole deviation is a common phenomenon in well drilling engineering which directly influences the wellbore quality and drilling speed and may causes huge economic loss. Composite borehole deviation and fast drilling technology not only can realize borehole deviation and fast drilling in vertical wells but also can realize continuous control of the locus of directional wells and improve drilling speed significantly and reduce the drilling times. Composite borehole deviation and fast drilling technology has wide application prospect in the area of large stratum dip.
