一种进化算法的应用研究

该文对丛式井组井口定位进行了研究。丛式井就是由同一井场出发打多口井,它可以发挥井场的最大作用,节约用地,提高经济效益。这样如何选择最优点进行打井就成为了一个关键问题。这个问题可以抽象为一个求平面多边形内最优点的问题。该文推导了较有价值的求解本问题最优解的算法,包括目前采用的经验法和基本的穷举法。该文在较新的进化策略算法方面做了一些改进,达到更好的效果。通过实例验证,进化策略算法较以往通常采用的算法有优势。

The Research on Evolutionary Algorithms of Wellhead Orientation

It is very important to process the application of orientation of collecting well group on engineering for horizontal well.This paper discusses the application of orientation of collecting well group.The application of collecting well group can make the track field exert much more function,save the tracking ground,decrease the exploiting cost,improve the economic benefit.Then how to select the correct point to set the well field becomes the key problem.The problem can be abstracted to the problem the shortest sum of distances to each peak of the polygon.The paper gives several algorithms :including experience method,following up method and so on.Furthermore,the paper makes some improvement on Evolutionary Algorithms to get much more effort of which superiority been proved by the examples.
