不同二类油层聚合物驱区块开发效果研究

摘要

本文根据二类油层工业化区块基本概况地质概况,通过物理模拟,对比分析二类油层各区块聚驱开采特点.研究注入压力、注入浓度、流动压力、产液量的变化及分层、注水、调剖等措施对波及效率、驱油效果的影响,建立一套判定聚驱驱替效果和调整注入参数的方法,实现实时分析油井生产数据、控制给小层波及状况、降低聚驱过程中的不确定性和风险因素,改善聚驱效果,提高油藏采收率.%In this paper,according to the basic situation of the two types of oil reservoirs,the physical characteristics of the two types of reservoirs are analyzed and compared.The injection pressure and the influence of concentration,flow pressure,fluid volume changes and stratification,water injection,profile control of sweep efficiency and oil displacement effect were studied,a determination method of polymer flooding displacement effect and adjustment of injection parameters was established,real-time analysis of oil well production data,to control layer affects the condition,to reduce the uncertainty in the process of polymer flooding and risk factors,improve the effect of polymer flooding,the oil recovery efficiency.
