摘要
文章深入研究了主成分分析方法。通过大量钻头使用资料分析,根据每米成本、进尺、机械钻速和井深4个因素构建综合指标来评价钻头的使用效果,该方法与钻头每米成本评价方法总体是一致的,但又体现了钻头带来的潜在效益。利用该方法对中原油田濮城区块沙河街组地层使用的钻头型号进行了评价优选,并评价出其中使用效果较好的几只钻头。经过现场初步应用,取得较好效果。
The paper deeply researched the method of principle component analysis. By analyzing a great number of working information of bits, the application effect of bit can be evaluated by the model according to the aggregate indexes of four factors such as the cost per meter,the footage of bit, penetration rate and the depth. It shows that this method has no difference with the evaluation method of bit cost per meter overall. But this new method objectifies the potential benefits of bit. Using this method, the type of bits used in the subterranean formation of Zhongyuan Oilfield had been evaluated. A few bits which had better application effect were picked out. After on site application, good economic effect has obtained.
