Abstract: CNPC Great Wall Drilling Company has developed and produced organic clay named Sinol Gel in large quantity for the purpose to localize oil-based drilling fluid, reduced OBM cost and improve its international competitiveness. Sinol Gel was produced by means of solid-liquid coupling method, which was used for the first time in China. The gelling ratio reached and even exceeded 98 percent while the temperature tolerance was up to 230℃. The performance of Sinol Gel was better than its domestic counterparts and could match with the world-leading organic clay from US MI Company. Helpful to clean production process, this product has been successfully used at more than 90 wells drilled with OBM in China’s Sichuan, Venezuela, Algeria, Cuba and Indonesia.

Key words: organic clay, high temperature tolerance, solid-liquid coupling method, clean production, world-leading
