摘　　要：研究了一套抑制碳酸盐岩结晶的高密度水基钻井液体系及现场复杂防控钻井液技术,安全钻进至完钻井深,全程无事故,不仅消除了低温下盐结晶对井控装备的影响,且阻止了井下盐岩溶蚀的进一步恶化,将有助于玛湖凹陷咸湖沉积环境页岩油的勘探开发。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.
