DFS System is the field version of the drilling fluid/drilling engineering digital/intelligent service series products (DFS Series Products) developed, designed and produced by CPBW for five years. Since 2020, the DFS System has been tested/verified at the sites affiliated to CNOOC, PetroChina and Sinopec, and relevant identification reports have been formed. To overcome the impact of the epidemic and the initial hesitation and hesitation in the market to accept new technologies/products, the first two-year service contract of PetroChina for DFS System was implemented on the first day of the New Year construction in 2022! The contract is based on the daily fee and lasts for two years. At that time, the contract will be renewed based on the actual situation.
