Comprehensive Research on Development of the New Blade Bits Design

摘要

This article presents data on the development of the peak-shaped blade bit with an increased productivity, resistance and reduced energy capacity used at drilling wells in soft rocks and partially in rocks of medium hardness. In order to achieve this goal a comprehensive research with the theoretical, design and development and experimental works were carried out. It is shown that the distribution of the axial load on the radial cutters of the bit is uneven, which is a reason for such complication as the "hanging" of the bit over the bottom of the well. As a result of the research works, the peak-shaped blade bit was developed and patented, which increases drilling productivity by 24%.
