Liaohe oil field block 58 for Huancai, the efficiency of production of thickened oil is low, and the efficiency of displacement is worse, likely to cause other issues. Researching and developing an type of Heavy Oil Viscosity Reducer for exploiting. The high viscosity of W/O emulsion changed into low viscosity O/W emulsion to facilitate recovery, enhanced oil recovery. Through the experiment determine the viscosity properties of Heavy Oil Viscosity Reducer. The oil/water interfacial tension is lower than 0.0031mN•m-1, salt-resisting is good. The efficiency of viscosity reduction is higher than 90%, and also good at 180°C.

Fluid Characteristics

Biosurfactants “U-Champ” is made by microorganisms, it could be changes the fluid characteristics which are, viscosity and Interfacial tension (IFT). In this study, will be presented the effect of Biosurfactan “U-Champ” injection into the heavy oil sample on laboratory experiment. Viscosity and IFT measurement was carried out in this experiment to analyze the characteristic changes. Coreflooding experiment also occur to measure the incremental of oil recovery. We used some of concetration of Biousrfactant “U-Champ” (1%;2,5%;5%;10%). In this experiment, we found 5% concetration of Biosurfactant “U-Champ” as the CMC value. The result of observation indicates the reduction of viscosity from 5.57 cp to 1.76 cp at 30oC, and from 1 cp to 0.95 cp at 80oC, and reduced the IFT value from 10.05 mN/m to 3.81 mN/m. Based on the result, Coreflooding experiment was occur to measure the incremental of oil recovery and obtained the increasing of recovery factor from 37,5% after waterflooding process to 81,25%. Finally, this studies feasible to continue in pilot project.
