摘　　要：在安全条件下,提高钻井速度是钻井工程技术人员追求的目标和紧迫任务。根据大庆长垣通用钻速方程,分析影响钻速的主要因素及提高钻速的有效途径,以供钻井工程设计及现场工程技术人员参考,并用莺深1井、达深2井实钻数据在通用钻速方程中验证,其预测钻速与实际钻速误差仅为4.3%和4.8%,取得较好的符合率。Under safety condition, improving drilling rate is the goal and urgent task for the drilling engineers and technicians. According to Daqing Changyuan general drilling rate equation, the analysis was made on main factors affecting drilling rate and effective approach to improving drilling rate, which was helpful for drilling engineering design. Actual drilling data of well Yingshen t and Dashen 2 were verified by general drilling rate equation with the fault only 4. 3% and 4. 8% between the predict and aetual drilling rate, good coincidence rate was acquired.
