摘要
在定性分析影响造斜率的基本因素的基础上,利用定量分析方法,导出了一含有多因素的造斜率计算公式,并对其进行了分析.影响造斜率的基本因素有:井底钻具组合结构参数、井眼几何参数、钻井工艺参数、地层特性参数和钻头特性参数.利用该公式可预测特定钻具组合的造斜率大小,也可根据设定的造斜率大小来设计钻具结构.
The main factors influencing deviation rate of horizontal well are analyzed, and a new formula containing many parameters for calculating deviation rate is deduced by means of quantitative analysis method. The influencing factors include structure of bottom\|hole assembly (BHA), wellbore geometry, drilling technology, formation and bit parameters. The new formula can be used to predict the deviation rate of a special BHA and to design BHA, a bottom\|hole assembly can be designed in the light of the planned range of deviation rate.
