| 摘 要： | 随着钻井采矿技术的应用从石油、盐井向天然碱井、煤层气等行业的日益拓展，钻进靶区面积越来越小，这对传统的中靶测量技术提出了严峻的挑战。不同时期的钻井测量技术，需要对应不同大小的靶区，以实现较高的连通率。针对MWD导向和高精度磁中靶导向技术，分析了各自的误差大小，提出了对靶区尺寸的基本要求。

| Abstract: | As the applications of drilling mining technology are extended from petroleum and salt well to trona solution and CBM mining industries, the thin or weak ledges can provide only a smaller target area, which makes the target-hitting more and more difficult.Different kinds of ranging technology depend on different size of target cavities so as to realize the con-nection between the drilling well and target well.In this paper, the analysis is focused on the deviation errors produced by MWD and rotary magnet ranging system, and the appropriate size of the cavity development is proposed. |
