New drilling fluid system

Development of drilling fluid system and additives is facing new breakthroughs to adapt to requirements of deep well, ultra deep well and complex formation drilling and increasingly valued environmental requirements, as well as further reduce drilling cost. New treatment agents have to adapt to ultra deep well requirements with stable temperature resistant performance and environmentally friendly, preventing formation damage and later environmental problems. New synthetic base drilling fluid will have further development. With deepening of environmental protection philosophy, environmentally friendly drilling fluid is leads the development trend. Low toxicity and non-toxic oil-based drilling fluid is given more attention. Due to rapid development of synthetic base drilling fluid, it has be
