摘要:  如何优选出既与所钻地层相匹配又经济有效的钻头,以实现安全高效钻井,一直是国内外学者不懈 努力的方向。提出了一种新的钻头主成分多层次模糊综合优选法,首先根据井史、完工报告等相关资料统计钻头 使用参数,利用多种多参数钻头选型方法对钻头进行初选;之后,采用主成分分析理论与模糊优选理论相结合的方 式,计算得到钻头选型的综合评价值,按照该评价值的大小顺序将与之对应的钻头型号进行推荐度排序。该方法 采用系统层次分析的方式将钻头选型流程分为三层系统单元,评价指标权重采用主客观结合的方式确定。现场应 用结果表明,该钻头选型方法合理有效,优选的钻头提速效果明显,现场推广和应用前景广阔,对于钻井提速增效 具有重要意义。

Abstract:

How to optimize the drill bit that is compatible with the strata being drilled and cost-effective to achieve safe and efficient drilling has been the domestic and foreign scholars unremitting efforts direction. A new method of drill bit selection is proposed, named principal component multi-hierarchy fuzzy comprehensive optimization method. Firstly, according to the well histories, completion reports and other relevant data, to statistic drill bit usage parameters, using a variety of multi-parameter bit selection methods to preliminarily optimize the drill bit. And then, the combination of principal component analysis and fuzzy optimization theory is adopted to figure out the synthetic appraisal values of drill bit optimization, according to the size of the evaluation value, the recommended degree of the corresponding drill bit is sorted. This method divides the drill bit selection process into three hierarchies of system units by means of systematic hierarchy analysis. The evaluation index weight is determined by the combination of subjective and objective factors. Field application results show that this method is reasonable and effective, the drilling speed of optimized drill bit is raised significantly. This method has broad prospects of promotion and application and is great important for increasing drilling speed and efficiency.

Key words:  , drill bit selection, principal component analysis, fuzzy optimization, systematic hierarchy analysis, evaluation index weight
