摘要
文章介绍了连接三角法一井定向的原理,结合实际工作经验分析了误差产生的原因,并提出了减小误差的方法。研究一井定向连接三角形最有利形状对提高一井定向精度有重要的意义,文章阐述了利用误差理论建立连接三角形平差模型,通过分析得出了连接三角形最有利形状。
The paper introduced the one well directional principle of the connected Triangle method. In combination with the actual working experiences, the causes of the error occurred were analyzed and a method to reduce the error was provided. The study on the most favorable shape of the triangle for the directional connection in one well would have important significances to improve the directional accuracy in one well. The paper stated the establishment of the connected triangle adjustment model with the error theory. The most favorable shape of the connected triangle was obtained with the analysis.
