对于某区聚驱来说,有机铬凝胶体系调剖技术应用较为广泛。本文主要基于某试验区油层发育状况及聚驱过程中存在问题对有机铬凝胶体系调剖技术进行深入分析,通过室内研究评价调剖体系成胶及稳定性,并结合动静态资料给出具体选井、选层等方法,进一步评价该技术在某区聚驱开发中效果。通过分析,确定有机铬凝胶体系对某区聚驱有较好效果,在聚驱前可以有效缓解层间、层内矛盾,降低聚合物低效无效循环,中期可增加油层动用厚度,提高开发效果。实践证明,有机铬聚合物凝胶调剖体系是改善聚驱开发效果有效措施,对于某区聚驱具有良好适应性。
For a certain area of poly flooding, organic chrome gel system profile control technology is more widely used. In this paper, based on the development of the reservoir in a certain experimental area and the problems existing in the process of poly-flooding, the paper deeply analyzes the profile control technology of the organochromium gel system, evaluates the gelation and stability of the profile control system through indoor research, Well selection, selection and other methods to further evaluate the technology in a district poly flooding development effect. Through the analysis, it is confirmed that the organochromium gel system has a good effect on poly-flooding in a certain area, which can effectively relieve the inter-layer and intra-layer contradictions and reduce the ineffective ineffective circulation of polymer before poly-flooding. effect. Practice has proved that organochromium polymer gel profile control system is effective measures to improve the development of poly flooding, for a certain area poly flooding has good adaptability.
