Through the comparison of synthetic base fluid properties, in combination with the characteristics of deep sea drilling, a study is conducted on a poly α-olefin synthetic base drilling fluid, which is of good and low temperature stability for effectively inhibiting gas hydrate and stabilizing the formation, the emulsifier for creating a poly α-olefin synthetic base drilling fluid is synthesized, screened and evaluated. Series treating agents, such as emulsifiers, fluid loss reducers are proposed for matching with the system, and through study of a treating agent for the synthetic base drilling fluid, a poly α-olefin synthetic based drilling fluid system is established in laboratory.
