取心钻进工艺方法的技术经济学分析——施工时间分析

Technical Economics Research on Different Core Drilling Methods——Drilling Time Analysis

介绍了一项取心钻进技术经济学研究的成果。此研究将技术经济学研究的思想引入钻探技术设计,实现取心钻进方法的评价和优选。推导了钻进施工时间的计算公式,并对几种国内常用的或正在改进完善的取心钻进工艺方法进行了评价。评价结果表明,液动潜孔锤钻进方法是一种值得大力推广的高效钻进方法。

The result of a technical economics research on core drilling methods is described in this article.This research aims at introducing the idea of technical economics in drilling technical design,to realize the optimization of core drilling method selection.The formula for calculation of drilling time has been deduced.Through calculation and comparison,several core drilling methods that are being widely used or just being improved in China,have been evaluated.The evaluation result shows that hydro-hammer dril...
