| 摘 要： | 井眼净化始终是斜井钻井中的关键问题之一.为了使现场的工程技术人员较准确地确定井眼清洗水力参数和施工参数,达到指导实际工程的目的,从实用的思想出发,以井斜角不同岩屑的运移机理和井眼清洗要求不同为依据,将整个井眼按井斜角的不同划分为多个井段,分段建立了能进行工程实际计算的井眼净化模型,并开发了相应的应用软件.该软件能依据给定的井眼条件和施工参数,预测是否能满足井眼净化要求;或从满足井眼净化的需求出发,给出合理的施工参数.

| Abstract: | Hole cleaning is one of the difficulties in drilling deviated wells.In order to help the on-site engineers and technicians to determine the hydraulic parameters and operation parameters for well cleaning accurately,the hole cleaning models are established.Since the migration mechanism of cuttings and the requirement to hole cleaning are different to different deviation angle,different hole cleaning models are established in different deviation angle ranges.The established models are suitable to practical en... |
