Method for assessing the performance of PDC for a drilling explorationtools

Abstract

The purpose of this work was to develop a rapid assessment method and a detailed study of the performance of PDC with activating additives in the destruction of solid rock. Experimental studies were carried out with longitudinal cutting with a given depth of penetration of the core surface of granite X of the category by drillability. The wear kinetics of PDC during cutting in real time were studied taking into account the change in the components of the cutting force. The PDC with an activating silicon additive showed a 42% higher wear resistance of the cutting edge in the destruction of solid rock compared to the work of the PDC of the serial production of the ISM, and also 1.14 times higher than the average value of the vertical component of the cutting force PY. Specific energy consumption of rock destruction  when working with a plate with an activating additive was 1.45 times lower than when operated by a serial plate due to a larger (in 1.64 times) volume of the destroyed rock, which indicates a more efficient plate with activating additive, which is provided greater wear resistance of its cutting edge. The use of PDC with an activating silicon additive in exploratory drill bits can be effective in extending the range of solid rock to be drilled due to greater wear resistance of its cutting edge
