摘要

在蒸汽辅助重力排水(SAGD)系统磁测距中，为了提高测量范围和方位的精度，提出了卡尔曼滤波方法，克服了磁场容易被井内套管干扰和衰减的问题。卡尔曼滤波可在钻孔过程中应用，适当的卡尔曼滤波深度可使精度提高至少一个数量级。

High precision magnetic ranging for Steam-Assisted Gravity Drainage system

In the magnetic ranging for Steam-Assisted Gravity Drainage (SAGD) system, the Kalman filtering is proposed to increase the accuracy of the measured range and azimuth, which overcomes the problem that the magnetic field is easy to be interfered and attenuated by the tube in the well. The Kalman filtering can be applied within the process of drilling, and the accuracy is increased at least one order with an appropriate depth of Kalman filtering.
