摘要: 重32井区齐古组油藏属于浅层超稠油油藏。自2007年投产后,至2011年2月,共有地表汽窜影响区域6个,汽窜点13个,减产317.7 t/d,导致247.3×104 t地质储量无法动用。通过井间电位监测技术查清地表汽窜通道,采用高温封堵技术从地下封堵汽窜节点井,从根源上治理地表汽窜,措施成功率达100%,取得显著经济效益。

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
