摘　　要：井斜控制是井身质量控制的关键因素,能够在极大程度上影响井底的水平位移增长速度。作为钻井工程中的难点,特别是哈萨克斯坦克孜项目KK区块钻井过程中,其地质特点具有地层倾角大、断层分布不规律等特性,井斜控制难度更大。基于此,文章以KK区块5口井斜控制情况为例,分析了井斜控制措施的应用效果,对该区块其他井井斜控制方式的选择具有一定的指导作用。Well deviation control is a key factor in wellbore quality control,which can greatly affect the growth rate of horizontal displacement at the bottom of the well.As a difficult point in drilling engineering,especially in the drilling process of the KK block of the Kyrgyz project in Kazakhstan,its geological characteristics have characteristics such as large stratigraphic dip angle and irregular fault distribution,making it more difficult to control well deviation.Based on this,the article takes the deviation control situation of 5 wells in KK block as an example to analyze the application effect of deviation control measures,which has a certain guiding role in selecting other well deviation control methods in this block.
