Temperature Model of an Advanced Artificial Lift Technology--Cyclic Nature Gas Heat Insulation and Geothermal Temperature Heating Technology

Abstract:

In view of the questions that heavy oil has badly flow condition and lifting efficient, and considering low carbon, energy conservation and environment as goal, an advanced artificial lift technology of cyclic nature gas heat insulation and geothermal temperature heating is developed, and the temperature calculation model of the technology was founded. The analysis that different cyclic nature gas volume, cyclic depth and oil production affect the formation produced fluid temperature distribution was made. The result is that the formation produced fluid temperature increases with the addition of cyclic depth and the function of rising temperature decreases from cyclic depth to wellhead, and that the formation produced fluid temperature increases with the addition of oil production and cyclic nature gas volume. A certain well as example, using the technology, the formation produced fluid temperature increases 11.14°C, compared to the conventional artificial lift technology. And it is favorable for surface transportation.
