Abstract
It is known that the multi-phase flows are widespread in the oil-gas production, as well as in the collection and transportation of hydrocarbons from offshore fields. These gravitational upward and downward flows are characteristic for the rising pipes of gaslift and flow wells, as well as for the risers of subsea multi-phase pipelines. A new approach for the estimation of the real parameters of multi-phase flows considering the phase displacement is offered in the paper and the perspectives of their definition based on the microscopic parameters of well operation shown as well. A possibility of the specification of the real density, real gas content and phase displacement of gas-fluid flows in the rising pipes of gas-lift wells based on the actual operation data in the context of the wells of Guneshli (OFP-15) offshore field is shown.
