During the period of 1920s~1960s, water-based drilling fluid was used. At that time, water-based drilling fluid was rather simple and the main type in this stage was dispersed water-based drilling fluid. (1) From 1921 to 1922, barite and iron oxide powder were used as weighting materials. (2) In 192
