[Abstract]:In order to solve the problem of orientation position optimization of gyroscope and adjustment of directional attached traverse in downhole control survey, the theoretical research and simulation analysis method are used synthetically. The optimization method and the general adjustment model of the conjunctive traverse along the isobaric straight extension direction are studied in this paper. The main conclusions are as follows: (1) based on the Lagrange multiplier method, the theoretical basis of the optimal direction attached traverse form of the gyro directional edge is discussed, and the different types of penetration are further analyzed. The law of gyroscope directional edge measurement with different orientation accuracy; (2) based on conditional adjustment, the adjustment model of directional traverse for any gyroscope is derived, and the correctness of the model is verified by an example of direction-attached traverse. The research results have important reference value for optimization and data processing of downhole directional attached conductors.
