| 摘 要： | 传统观念认为从钻井轨迹的计算得出的中靶精度即为实际中靶精度，随着钻井技术及测量技术的不断发展，这种观念在被逐渐打破。在数学计算模型中的靶点位置与实际的靶点位置有相当大的出入，即使使用主动磁测量技术测得的靶点位置也是存在不确定性。由H1-H2井组的对接施工过程作为案例，分析出现这种不确定性的原因，以及在施工中采取主动的手段完成工程任务，以达到施工目的。

| Abstract: | In the traditional view, the target accuracy derived from the calculation of the drilling trajectory is the actual target accuracy, but along with the development of drilling technology and measurement technology, this concept is gradually broken. There is considerable discrepancy between the target location calculated by mathematical calculation model and the actual location in practical operation, even the target location measured by active magnetic measurement technology is uncertain. With H1-H2 well group as the case, the reasons of this uncertainty are analyzed and active means were adopted to complete the project in the construction. |
