Indoor experimental methods were used to complete the optimization of ultra-low temperature drilling fluid base fluid and ultra-low temperature drilling fluid treatment agent, forming the dataset. The dataset contains the elements of apparent viscosity, plastic viscosity, dynamic shear force, filter vector, density, pressure, and filtration area. The indoor experiment of this project started on March 1, 2019 and ended on April 30, 2019. The collection location was in Qingdao, Shandong Province, and a total of 26 indoor experiments were conducted. The experimental dataset was fully open and shared.
