Title: Weidong Zhou: Innovator in Rock Drillability and Cementing Engineering
Introduction
Weidong Zhou is a notable inventor based in Shandong, China. He has made significant contributions to the fields of rock drillability evaluation and cementing engineering. With a total of 2 patents, his work addresses critical challenges in the oil and natural gas industry.
Latest Patents
One of Zhou's latest patents is a method for evaluating rock drillability by nano-indentation test on rock cutting. This innovative method involves conducting a nano-indentation test on a rock cutting sample, acquiring a displacement-load curve of an indenter, and calculating micro-hardness. It also includes calculating the mineral composition of the rock cutting sample based on the statistical distribution characteristic of the micro-hardness. This method effectively overcomes the limitations of sample size and shape in conventional testing, providing a solution for mechanical parameter testing of deep rocks.
Another significant patent is related to a foam stabilizer composition, foamed cement slurry, and an additive composition thereof. This invention is particularly relevant to oil and natural gas well cementation engineering. The foam stabilizer composition includes C6-C20 alkyl amido alkyl amine oxide, C6-C20 alkyl amido alkyl betaine, and triterpenoid saponin compound. The composition enhances the stability of foamed cement slurry, making it suitable for well cementing operations in oil and natural gas exploration and development.
