Intelligent drilling fluid is a new research direction in the oil drilling industry. Compared with the problems of insufficient directivity, weak adaptive ability, difficult monitoring and overly cumbersome manual operation of traditional drilling fluids, intelligent drilling fluids have better targeted, drilling fluid The performance is more prominent, and at the same time, the degree of manual intervention can be greatly reduced. Therefore, the research on the intelligentization of drilling fluid is of great significance. This article reviews the synthesis and development of intelligent drilling fluid chemical system, the enhancement of the function of drilling fluid intelligent auxiliary system, the development and application, and the current status of the main research. Other research directions have been developed, but in terms of intelligent chemical systems, precise control of drilling fluid performance parameters has not yet been achieved. The intelligent direction in the development of intelligent drilling fluids and the construction of intelligent drilling fluid platforms is too single to meet the needs of current drilling sites. It is suggested that the intelligentization of drilling fluid in the future should develop in a comprehensive and diversified direction.
