Effects of Pressure, Temperature, and Type of Oil on Vaporization of Oil During Gas Cycling

摘要

Data are presented to show oil vaporization resulting from the passage of natural gas through a sand-packed tube saturated with synthetic reservoir oils. The Bureau of Mines performed 13 experiments, using reservoir oils synthesized with base crude oils of approximately 22 deg, 35 deg, and 45 deg API, at 100 deg, 175 deg, or 250 deg F and 1,100, 2,600, or 4,100 psia. It has been determined that the amount of vaporization is significant if proper conditions exist. These experiments show that oil vaporization depends on pressure, temperature, volatility of the oil, and amount of gas cycled. Increases in each of these conditions increase the volume of oil vaporized. (Author)
