Title: Innovations by Xianbo Lei in Rock Drillability Evaluation
Introduction
Xianbo Lei is a notable inventor based in Qingdao, China. He has made significant contributions to the field of rock drillability evaluation through his innovative methods. His work is particularly relevant in the context of deep rock mechanics, where traditional testing methods often face limitations.
Latest Patents
Xianbo Lei holds a patent titled "Method for evaluating rock drillability by nano-indentation test on rock cutting." This method involves conducting a nano-indentation test on a rock cutting sample to acquire a displacement-load curve of an indenter. It also includes calculating micro-hardness under the nano-indentation test and determining the mineral composition of the rock cutting sample based on the statistical distribution of micro-hardness. The method transforms micro-hardness into macro-hardness and calculates a rock drillability grade based on the correlation between macro-hardness and rock drillability. This innovative approach addresses the challenges posed by limited downhole rock samples and high testing costs.
