【摘要】 钻井过程中保证井眼清洁有利于安全高效地钻进,钻进时加放岩屑床清除器能有效保证井眼的清洁。通过对Moore滑落末速公式的修正引用及岩屑床清除器的流场分析,得出岩屑床清除器的加放间距的简单计算方法,对现场施工具有指导意义。更多还原

【Abstract】 In the process of drilling,keeping the hole cleaning is important for drilling safely and efficiently.Cutting-bed-remover is added when drilling can effectively guarantee the wellbore cleaning.Quotes from Moore particle slip velocity formula and flow field analysis of cutting-bedremover is amended,a simple method of calculating spacing for cutting-bed-remover in highly deviated well simple calculation method is given to guide the construction in this article.更多还原
