摘要

Abstract

Foam fracturing is an important technology in the development of low permeability oil/gas reservoirs. The heat transfer characteristics of foam fracturing fluid are directly relevant to the calculation of pressure drop in the well

the optimum choice of fracturing parameters and the accurate evaluation of fracturing results. CO2 foam fracturing fluid behaves as a non-Newtonian fluid. The convective heat transfer characteristics of CO2 foam fracturing fluid were experimentally investigated on the newly constructed large-scale test loop under downhole conditions with CO2 in supercritical state

the pressure up to 40MPa. From the test data

corresponding correlations for convective heat transfer were obtained and the influences of pressure

temperature and flow rate were also studied. The convective heat transfer coefficient increased with the increase of temperature and flow rate

while the effect of pressure was much more complicated.In most cases

with the increase of pressure the coefficient tended to decrease.
