聚驱跟踪调整措施的优化设计

Optimization and Design for Measures Tracking and Adjusting Polymer Flooding

针对聚合物驱过程中不同阶段出现的油层非均质性严重、注入压力低、存在高渗透层或高吸水层、层间渗透率级差大、注采困难、生产井流压较高等问题进行了跟踪措施调整,在总结已有现场试验和做法的基础上,通过数值模拟与矿场试验相结合,对注聚合物工业化区块的开发及调整措施效果进行了综合评价分析,建立了聚合物驱过程中综合调整措施优化方法,完成了聚合物驱降本增效技术的筛选.

Due to the emergence problems such as serious inhomogeneity of oil layer, low injection pressure, highly permeability or water accepting layer, high permeable contrast between various layers, difficult injection and production, and high flowing pressure in production well, measures tracking and adjusting polymer flooding were taken based on the fact that practical experience was acquired during the industrialized popularization and application of Daqing oilfield in China. Compositive valuation and analysis of measures for exploitation and adjustment in zones that applied industrialized polymer flooding were carried out. Optimization methods of compesitive adjusting measures during polymer flooding were foundation. Technologies for screening and valuating of enhancing benefit were studied. And, optimization design methods in measures track and adjusting polymer flooding were studied through numerieal simulation and field experimentation.
