吉林油田CO2试验区数值模拟和方案设计

SIMULATION STUDY TO DESIGN CO2 FLOOD PLOT IN JILIN OILFIELD

    摘要
  • 摘要: 数值模拟和油藏工程研究相结合,对吉林油田CO2试验区方案进行优化设计,并对最优方案作了长期预报。研究结果表明,试验区对CO2驱有较好的适应性。CO2合理用量为15%HCPV,最佳注入方式为段塞尺寸逐渐减小的改进交替注气水方式。达到经济极限产量时,试验井组内CO2可波及区采收率提高15.9个百分点。

     

    Abstract: Reservoir engineering research and reservoir simulation study were conducted to design and optimize the CO2 flood project in Jilin oilfield. The result shows that the reasonable total amount of CO2 is 15%HCPV, and the optimum injection style is suggested as tapering WAG (water-alternating-gas). When the oil production reaches the economic limit, an additional recovery of 5.2 percent of original oil-in-place(OOIP) within the well pattern or 15.9 percent in the CO2 flooded area can be achieved.
