Experimental Study And Economic Evaluation Of Low Temperature Drying Treatment Of Abandoned Water-Based Drilling Fluid, Li Zhijun, Liu Xusan, Wang Bo, Zhao Wei

Coal Geology & Exploration

Abandoned water-based drilling fluids are the waste of oil drilling engineering operations. It will not only keep the cost of drilling fluid high, but also have a very adverse impact on the environment if it is directly discharged. Reusing of abandoned water-based drilling fluid after low-temperature drying treatment is one of treatment methods which is economic and conforms to the modern development trend. In this paper, the experimental study and economic evaluation of the low-temperature drying technology of polymer drilling fluid system, sulfonated drilling fluid system and Sichuan shale gas well drilling fluid system were conducted. The results show that …
