摘要
Abstract
The"four in one"drilling tool is a directional drilling tool that combines the drill bit,screw,short drill collar,and stabilizer in a fixed order.It has a double stabilizer rigid structure.By utilizing the characteristics of a single bending screw,it is possible to achieve anti deviation straightening in the straight section,sliding directional drilling in the inclined section,and composite drilling in the stable,increased,and lowered sections.This article focuses on the different effects of different"four in one"drilling tool combinations on wellbore trajectory control.Combining with the construction case of Tao7-15-17X1 natural gas development directional well drilling project,the key factors affecting wellbore trajectory control by this drilling tool combination are discussed.The main reasons why different drilling tool combination parameters affect wellbore trajectory control are analyzed,which is of great significance for promoting the development of directional well trajectory control technology and improving the efficiency of directional well drilling construction.关键词
