J230井区齐古组油藏是九区齐古组边缘的岩性构造控制的低饱和度稠油油藏,2008年～2010年进行了加密调整。通过系统总结分析调整后油藏注蒸汽开发中的注采特征及变化规律,掌握了影响热采动态特征的主控因素;动静结合,采取有针对性的治理措施,加密调整井取得了良好的生产效果,总体达到了方案设计产能。油藏年采油速度保持在2%以上,综合递减下降了10.9%,采出程度提高2%,为保持J230齐古组J3q3层高效、持续、稳定开发及进一步充分挖掘油藏潜力、提高采收率具有重要的现实意义。
The Qigu Formation reservoir in J230 well is a low-saturation heavy oil reservoir controlled by lithologic tectonics on the margin of the Qigu Formation in the 9th District. From 2008 to 2010, it was encrypted and adjusted. Through the systematic analysis and analysis, the key characters and rules of injection and production in the steam injection steam development of the adjusted reservoir are mastered. The main controlling factors that affect the dynamic characteristics of the thermal recovery are grasped. Combining the dynamic and the static control, the targeted control measures are taken and the well Production results, the overall plan to achieve production capacity. In order to maintain the high efficiency, sustained and stable development of J3q3 layer of J230 Qiugu Formation and to further fully tap the potential of the reservoir and enhance the recovery of production, the annual oil recovery rate of the reservoir should be maintained at above 2%, with a decrease of 10.9% in aggregate decrease and an increase of 2% in recovery. Rate has important practical significance.
