套管井井身轨迹测井技术

文章介绍了一种用于已下套管的油水井重新测量其井身轨迹的动力调谐陀螺测井技术。这项技术以动力调谐速率陀螺测量地球自转角速度分量 ,以石英加速度计测量地球重力加速度分量 ,经计算机解算可得出井筒的倾斜角、方位角、工具面角等参数。通过对井筒不同深度的测量 ,即可得出井身轨迹曲线。可应用于有磁屏蔽的套管、油管、钻杆内和有磁干扰的丛式井组进行井眼轨迹测量以及定向钻井

Well body trace logging technology for cased wells

This paper introduces a kind of dynamical tuning gyroscopic logging technology to re survey the well body track in cased production and injection wells. It uses dynamical tuning top to survey the directional of rotation angle velocity of the earth, and uses quartz accelerometer to survey the directional of acceleration of gravity, then to calculate the parameters such as the dip angle, azimuth angle, etc. by computer. Well body track curve can be drawn out through surveying the depth in the hole. It can be applied in casing, tubing and drill pipe with magnetic shield, and cluster well pattern with magnetic disturbance and directional drilling.
