基于改进ID3算法的轨迹化决策研究

Research on track optimization based on improved ID3 algorithms

初步对决策树算法在钻井工程中水平井方面的应用进行了研讨。在水平井钻井工程中,轨迹优化设计的重要性不言而喻,它对整个的施工过程都具有重要的指导意义。在工程实践中,主要是依据设计人员的经验来确定造斜点位置,从而确定整个优化轨迹。这个过程中,设计人员的经验决策起了主要的作用,这就为应用决策树学习算法来学习设计人员的决策经验提供了可行性。基于此思路,应用改进了的ID3算法,进行了初步实现。

The application of decision tree arithmetic on engineering for horizontal well is discussed. It is very important for optimizing design of well trajectory to the construction of horizontal well. In practices engineering, it is mainly relying on the operators' experiences to ensure the position of the making lean point and to design the whole optimize track. During the source, the experiences of the designers plays the main pole for which apply the feasibility of applying the decision tree to study the decision of designer. Applying the improved ID3 arithmetic makes the research based on this thoughtfulness.
