Oil production optimization and enhanced recovery method and apparatus for oil fields with high gas-to-oil ratio |
摘要 |
A method for optimizing oil production rate from an oil well with high gas-to-oil ratio is disclosed to include modeling an Inflow Performance Relationship curve and calculating an optimal level of bottomhole pressure to be higher than zero. Maintaining the bottomhole pressure at that calculated optimum level by using a bottomhole tool of the invention or other known means such as gas injection provides for maximum oil recovery from a given well. The bottomhole tool includes a multi-stage flow resistor and a needle moved in and out of the resistor by a spring-biased piston responsive to a difference in pressure between a bottomhole pressure and a pipe pressure. Automatic adjustment of the bottomhole pressure is maintained over a wide range of operating parameters throughout the life of the well.
