摘要
This paper discussed and analyzed an important parameter—build-up intensity which influences the hole section designed. It has established the build-up intensity model through the whole stress analysis on drilling tool and has obtained the formula of build-up intensity affected by the resistance of soil and the curve of drilling tool in the preliminary stage of angle building. Then it analyzes the primary factors that affect the build-up intensity in the basis of formula and has got some conclusions. This paper also gives qualitative explanation on the rule of continuous build-up intensity by indoor tests.oft-com:office:office" />
