水平井咨询系统的原理与应用

Theory and Application of Horizontal Well Advisement System

水平井咨询系统是利用连续的井斜和井斜方位曲线确定水平井的井眼轨迹 ,再结合测井资料判断水平井是否钻遇了目的层以及钻遇了目的层靶点的位置等 ,为测井解释和地层评价提供准确的水平井咨询。简要介绍了水平井咨询系统的原理和处理方法 ,通过实例重点介绍了水平井咨询系统在提高测井解释准确性方面的实际应用效果。

In Horizontal Well Advisement System, the continuous well deflection and azimuth curves are used to determine the hole trajectory of the horizontal wells. Combining with log data, the system allows us to judge whether the intervals of interest is drilled or not, and determine the target points of the intervals, thereby providing precise consultation information for logging interpretation and formation evaluation. In this paper, we introduce briefly the principle and processing method of Horizontal Well Advisement System. The applications have proved this system can improve interpreting precision.
