Research on inhibiting carbonate crystallization drilling fluid technology of Fengyun 1 well
In this paper,a set of high-density water-based drilling fluid system and complex on-site prevention and control drilling fluid technology have been developed to inhibit carbonate crystallization,safely drilling to the complete drilling depth without accidents,not only eliminating the influence of salt crystallization on well control equipment at low temperature,but also preventing the further deterioration of underground salt rock dissolution,which will contribute to the exploration and development of shale oil in the sedimentary environment of the salty lake in the Mahu Depression.
