This dataset compiles and collects experimental research data on the performance evaluation of low-temperature drilling fluid formulations during project implementation. Indoor experimental methods were used to establish and evaluate water-based drilling fluids with excellent low-temperature rheology, forming a dataset that meets the assessment criteria. The low-temperature viscosity increase rate AV (0 ℃)/AV (30 ℃) of the low-temperature antifreeze drilling fluid system is less than 2. The main elements of this dataset include apparent viscosity, plastic viscosity, dynamic shear force, filter vector, density, and pressure. The indoor experiment of this project started on February 1, 2019 and ended on February 28, 2019. A total of 17 sets of indoor experiments were conducted in Qingdao, Shandong Province, and the experimental dataset was fully open and shared.
Independently generated.
Data collection was conducted using a low-temperature test chamber in the laboratory of China University of Petroleum (East China) to create a low-temperature environment. Six speed rotational viscometer, medium pressure filtration apparatus, and drilling fluid were placed in the low-temperature chamber for testing the filtration loss and rheological properties of the drilling fluid.
