Using Interwell Electric Potential Monitoring Technique to Control Surface Steam Breakthrough in HeavyOil Reservoir of Zhong32 Wellblock in Junggar Basin

Abstract

Abstract: The Qigu reservoir in Zhong?32 Wellblock of Junggar basin belongs to a shallow super heavy?oil reservoir. Since bringing into production in 2007, the first surface steam breakthrough occurred in September 2007. Up to February 2011, there are 13 surface steam breakthrough spots appeared in 6 areas, and 138 wells have been affected by 317.7 t/d reduction of output, resulting in that 247.3×104 t OOIP can not be produced. By using the interwell electric potential monitoring technique to verify the surface steam breakthrough channels, seal the steam breakthrough node well from underground by means of high temperature formation sealing technique, the surface steam channeling problem have been well solved, with measure successful ratio of 100% and remarkable economic benefits
