Abstract: Drilling fluid techniques have been enhanced in an all-round way, with the development of China's oil industry. Statistics show that CNPC owns more than 5200 employees, more than 2000 technicians, and over 100 senior technical experts, with technical service and products sales covering both home and abroad, and annual income exceeding 4 billion RMB. Now the 3 systems and over 100 drilling fluid technical series developed by CNPC could basically meet the requirement of various complex strata and drilling. In recent years, the construction in high-temperature ultra-deep wells, horizontal wells, and extended reach wells got more difficult, as the targets for exploration and development became increasingly complicated. In addition, the "going-out" pace sped up continuously, so the requirement on technical performance of drilling fluid got unprecedentedly high, and forging efficient drilling fluid technical service was faced with a series of new challenges. This paper introduced CNPC's important achievements in drilling fluid techniques, analyzed the complex environment for the development of drilling fluid business, and proposed the development orientation during the "12th Five-Year Plan" period.
