| Abstract: | Through a lot of studies and experiments, the surfactant JHSS-01 has been developed. This surfactant is cheap, salt resistance, with good rigidity, and it may reduce the viscosity of heavy oil through emulsion, thus improving the percolation rheological characteristics of non-Newtonian crude oil. Lab simulation indicates that the oil production rate can be increased by 20-50% through taking in and sending out a large quantity of JHSS-01.In Bamianhe and Jianghan Wanchang oilfields, pilot projects have been conducted with this surfactant, additional 1283t oil has been produced in 7 wells .The input- output ratio is 1:5.2, and economic results have been obtained. |
