TY - Data T1 - Optimization data set of ultra-low temperature drilling fluid base fluid and treatment agent (March April 2019) A1 - Gao deli DO - 10.12072/ncdc.SRIPE.db1692.2022 PY - 2022 DA - 2022-02-25 PB - National Cryosphere Desert Data Center AB - This dataset compiles and collects the optimal selection of ultra-low temperature drilling fluid base fluid and treatment agent during the project implementation period. 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.
