This paper introduces the principle and method of using acid residue and asphalt semi-finished products as raw materials to produce drilling anti-sticking additive. Acid residue from Nanchong refinery lubricants sulfuric acid refining process. Asphalt semi-finished products from the vacuum residue isopropyl alcohol deasphalting process. The text provides the principle of the process, the nature and use of the product. The research provided new technologies and good economic benefits for eliminating the acid residue pollution, purifying the environment and comprehensive utilization of acid residue, and obtained a profit of 250,000 yuan per year.
