TY - Data T1 - Ultra low temperature drilling fluid formula optimization and performance evaluation data set (May June 2019) A1 - Gao deli DO - 10.12072/ncdc.SRIPE.db1713.2022 PY - 2022 DA - 2022-02-25 PB - National Cryosphere Desert Data Center AB - During the implementation of the project, the data set of ultra-low temperature drilling fluid formulation optimization and performance evaluation is sorted and collected in this data set. The indoor experiment method is used to complete the optimization of ultra-low temperature drilling fluid formulation, the performance evaluation of ultra-low temperature drilling fluid and the construction of drilling fluid formulations in different low temperature ranges, forming a data set. The main elements of the data set are apparent viscosity, plastic viscosity, dynamic shear force, filtration vector, density, pressure and filtration area. The indoor experiment time range of the project starts from May 1, 2019 and ends on June 30, 2019. The collection place is Qingdao City, Shandong Province. A total of 27 groups of indoor experiments have been carried out, and the experimental data set is fully open and shared.
