| 摘 要： | 提出了水平井轨迹“曲率－并斜角”二段控制方法，即以初始控制点为起始．点，控制段终点为目标点，用两种造斜率控制井段，根据造斜特点决定中间点的井斜角大小，找出二造斜段的配伍曲率，从而满足控制要求．文中给出了中间点的选择和控制段的确定方法，并对塞平－１井作了实例分析．结果表明，该方法简便，灵活，实用性强． |

| Abstract: | two-section controlling method of controlling the curvature-drift angle is presented in this paper.In this method,controlling started at the initial controlling point and ended at the final controlling point.The section was controlled by two kinds of curvature' The drift angle of the intermediate point in the controlling section was determined according to the features of deviating and the matching curvature of the two deviating sections was found to meet the requirement of controlling The method of selecting the imtermediate point and determining the section is given in the paper. The controlling practice of this method in SP-1 Horizontal well is analysed. The results show that the method is easy,flexible and practical. |
