The accuracy requirement of monitoring and controlling the trajectory of horizontal well in drilling is higher and higher, especially in the old wells and ultra dense marginal reservoirs wells. Due to the environment, the precision of the instrument, the change of the magnetic field, and so on, the influence of the factors on the measuring instrument in the measuring process is measured. So there is deviation between the real drilling trajectory and design trajectory. By recognizing the importance of measuring instrument error on trajectory control, this error can be reduced in slim hole trajectory control, and it also can improve the control precision of the well trajectory. It can reduce the ri
