概述钻井作业的主要目的是以经济、高效、安全的方法获得质量合乎技术要求的钻孔.机械钻速是衡量钻井工作效率的重要指标.随时监测钻速的变化,可以帮助判断孔内钻进状态,及时调整钻进参数,保持合理的机械钻速,使钻进过程处于最优条件下进行.传统的人工计算钻进速度方法的主要缺点在于每次测取读数时间过长.在中硬地层使用金刚石钻头钻进,至少需半小时才能有供测取的钻杆移动,需要几次比较才能选定钻进参数
Overview The main objective of drilling operations is to obtain drilled holes of a quality that meet the technical requirements in an economical, efficient and safe way.Raw penetration is an important indicator of the efficiency of drilling operations.During the monitoring of the variation of the drilling speed, it can help to judge the drilling in the holes State, timely adjustment of drilling parameters, to maintain a reasonable rate of penetration, the drilling process in the optimal conditions for the traditional manual calculation of drilling speed method is the main disadvantage of each reading time is too long reading in the hard Strata drilled with a diamond drill, it takes at least half an hour to move the drill pipe for the test, a few more times to select the drilling parameters
