Core Initiation Pressure Gradient Tester

Core Initiation Pressure Gradient Tester


(1) Determination of single-phase fluid startup pressure: Select different fluids (kerosene, simulated oil, formation water, injection water, distilled water, etc.) for core displacement experiments to obtain the startup pressure of each fluid flowing through the core; (2) Measurement of oil-water two-phase startup pressure gradient: Select oil-water two-phase for displacement experiments, respectively conducting: ① oil phase startup pressure under bound water conditions ② water phase startup pressure under residual oil conditions; (3) Study the influencing factors of the water lock effect and its prediction methods: Accurately determine the gas phase and oil phase permeability values of gas reservoirs and oil reservoirs before and after contamination by drilling fluids or other media, and evaluate the damage caused by different drilling fluid systems to gas reservoirs and oil reservoirs.
