Abstract: At a time when environmental protection is becoming more and more important, how to effectively deal with the oil and gas generated during gas well testing in the offshore high production well is very important.Combined with John F.Widmann's simplified Mie scattering theory, calculation and simulation are conducted.Summarizes are conducted based on the existing oil and gas processing technology for offshore gas well testing, the new operation mode of environmental protection ship + super sprinkler system is established.Combined with the actual oil and gas processing results of high production gas wells in Block BZ, a set of oil and gas processing technology suitable for offshore high production gas wells is finally formed.
