%X This dataset is generated through simulation calculations using a self-developed software module for optimizing the hydraulic parameters of deepwater subsea pump dual gradient drilling. The basic simulation conditions are sea surface temperature of 0 ℃ and water depth of 1500m. By simulating the hydraulic parameters of the return pipeline under different water depths, inner diameters of the return pipeline, and drilling fluid densities, the required pump pressure and pump power data of the subsea pump under different conditions are obtained, which serve as the basis for optimizing the parameters of the subsea pump and the size of the return pipeline. The dataset consists of 165 sets of data, with each set containing 2 data points, and the dataset is fully open for sharing.
