| 英文摘要 | MWD (Measurement While Drilling) technology require greater precision for the high precision of magnetic azimuth with the emergence of horizontal wells and multi-branch wells. The normal correction for magnetic azimuth have a relatively big error that cannot meet the request of horizontal wells and multi-branch wells. In recent years, many people has derived a series of algorithm to improve multi-station analysis based on the multi-station analysis of Brooks in foreign countries. But, there is no such high precision magnetic azimuth correction algorithm in China. This paper deduced an improved multi-point analysis algorithm based on the multi-station analysis method and a single point analysis method, and the algorithm is convergence. Then we make an experiment to verify the effect of the improved multi-station analysis method in the laboratory. The azimuth that is corrected by improved multi-point analysis algorithm very close to real azimuth, and its accuracy is within in 0.2 degrees. The results show that the improved multi-station analysis can improve the precision of the magnetic azimuth and reach or approach advanced international standards, which is suitable for the drilling process of the larger slope. This algorithm meet the demand of a high precision magnetic azimuth correction in China. |
