An Experimental Study of Oil-Gas-Water Three-phase Flow Regimes

Visual experiment on flow regimes of oil-gas-water flow in a 40 mm bore horizontal pipe were carried out at a pressure of 0. 4 MPa. Characteristics of observed flow patterns were described and a flow pattern map were generated. The observed flow could be classified into seven patterns. They were water-oil based wavy flow, slug flow, and stratified flow. Also many new flow regime configurations were found in this paper.
