In order to research the influences produced by sidetracking position, the primary hole deviation and azimuth of used wells on the primary section of the re-entry horizontal wells, it is necessary to consider the 3d trajectory design of the re-entry horizontal wells 为了考虑侧?点位置及老井的初始井斜、方位对侧?水平井起始段的影响,需要对侧?水平井进行三维轨迹设计考虑。
The method can not only satisfy the oilfield construction condition and the well trajectory design while drilling, but also assure the designed well trajectory to be the most slip, the shortest and possible optimized well trajectory 此方法不仅能够满足现场施工条件的限制和待钻井眼轨迹设计的要求,而且能够确保得到的待钻井眼轨迹为一条最光滑的、最短的、可行的最优待钻井眼轨迹。
