Abstract

Due to the large fluctuation of pressure difference between injection and production wells during the preheating and start-up process of SAGD steam injection cycle in continental heterogeneous ultra-heavy oil reservoirs in Xinjiang Oilfield,it is difficult to control on site.Steam is easy to enter the oil layer of high permeability horizontal section,which is easy to cause local preferential connection or steam channeling in horizontal section.The development of steam chamber is not balanced, which leads to the low utilization degree of horizontal section,thus affecting the production effect of SAGD.Therefore,the development method of putting electric heaters into the horizontal section of SAGD in double horizontal wells is proposed.The oil layer between injection and production wells is uniformly heated by the principle of heat conduction,and the key operation parameters of SAGD electric heating preheating start-up are optimized,including SAGD electric heating start-up wellbore pretreatment,fluid replacement cycle operation parameters and SAGD production time.The SAGD electric heating preheating start-up operation process is formed.SAGD electric heating preheating start-up field test was carried out in the shallow ultra-heavy oil double horizontal well of FHW01TW Well Group in Chong A Well Area of Xinjiang Oilfield.The preheating startup time was reduced from 320 days to 163 days,3.79×104 t steam was saved and 4 846.6 t CO2 emission was reduced.This technology will become one of the important means to reduce CO2 emission in SAGD development of shallow double horizontal wells.
