摘　　要：石油钻井测斜参量的量传方法是技术监督部门对定向测斜仪器的计量管理方法,其参量量传体系中倾角和工具面角的量传可通过倾角仪和国家标准进行传递,但磁方位角的量传目前国内尚无直接的标准可进行传递。因此,通过天文测量定位、建立磁偏角校正模型,在绝磁数显转台上建立了一个高精度的磁方位基准,为定向井测斜仪器磁方位角的量值传递与溯源提供了基准源头,从而建立了石油钻井测斜仪磁方位角的量传方法。石油钻井测斜仪参量的量传方法对定向井测量仪器和测量标准器的定期检定管理具有重要的意义。Surveying data transmission method in well drilling is the measurement control method used by technical supervision department. Wellbore inclination and toolface angle can be transmitted by clinometer and state specifications, while there is no general standard for magnetic azimuth data transmission. Therefore, a magnetic azimuth reference with high accuracy has been established on a non-magnetic digital rotary console based on astronomic surveying and a compass declination correction model, which provides the reference for magnetic azimuth. The surveying data transmission method is important for checking and correcting directional surveying instrument regularly.
