Study on pattern transition of oil-water pipe flow

CHEN Jie, YU Da, YAN Da fan (Department of Petroleum Engineering, Petroleum University, Beijing 102249,China)  
New criteria for oil water pipe flow pattern transition principle was developed, according to the characteristics of two phase flow in the steel pipe, including the stability criterion of oil water stratified flow, the regime transition lines of dispersion flow, semi stratified flow and semi dispersion flow and oil water inversion. The predictied results agree with experimental flow pattern of white oil water and diesel oil water two phase pipe flows, and some discrepancy exists when compared with the experimental flow pattern results in acrylic resin tubes, which is consistent with experimental result of P.Angli. Research indicates that the flow pattern transition criteria presented in this paper can predict the oil water flow pattern in steel pipe well, which is of great importance for the design and operation of multiphase flow pipe in oil field.
