Abstract: Before 2017, clean production of traditional drilling in Sichuan and Chongqing area mainly adopted real-time solidified landfill technology to treat drilling debris. To adopt this technology, large areas are needed. The anti-risk ability of landfill pools is weak. The final disposal of wastes cannot be realized. There are high environmental risks. In 2017, in order to promote clean production of drilling continuously, Chuanqing Drilling Engineering Company Limited carried out the application of reutilization technology of drilling debris in ultra-deep wells in Western Sichuan and truly realized the goal of reutilization of drilling debris in accordance with the general idea of “less production, reutilization and zero emissions”. Up to now, this technology has been used to treat 58600 cubic meters of drilling debris and 26.4 million bricks have been fired, achieving 100% reutilization of resources. The fired bricks met the requirements of relevant standards. This proved the feasibility of the technology and the treatment mode and provided technical guarantee for the large-scale application of this technology in Sichuan in the future.
