摘要:
在国内外尚无成熟、有效的聚合物驱末期提高采收率技术的情况下,如何在含水回升期充分挖掘聚合物驱剩余潜力,对进一步提高油藏采收率具有重要意义。综合应用模糊数学、经验回归、驱替特征曲线及分类图版等方法,可以定量预测聚合物驱在含水回升期的剩余潜力,并将剩余潜力值细化到井组。依据井组动态特征,对分注、调剖、压裂等挖潜效果进行了定性、定量评价。该方法在A区块进行了现场应用,调整后的采出程度提高了1.89百分点,增油量14.48×104 t。该研究成果可为聚合物驱在含水回升后期的开发方案调整,并最大程度地提高阶段采出程度提供理论依据。
Abstract:
When there is no mature and effective EOR method at the end of polymer flooding at home and abroad, how to fully exploit the residual potential of polymer flooding in water-cut rising period is of great significance to further improve the recovery degree. By applying fuzzy mathematics method, experience regression method, displacement characteristic curve and classification chart method, the rest of the potential value for the polymer flooding in water-cut rising period is refined to the well group. According to the dynamic characteristics of well group, the potential exploitation measures, such as layered water injection, profile control and fracturing, are evaluated quantitatively and qualitatively. The application in A block shows that recovery rate increase by 1.89% with oil production increase of 14.48×104 t. The results of this study can guide the development adjustment in later water-cut rising period of polymer flooding, and provide theoretical basis for the maximum improvement of the staggered recovery.
