摘要

为了有效监测多段塞逐级调控过程中地层参数和波及状况的动态变化情况,结合裂缝性特低渗透油藏逐级深部调控技术主要特点和化学示踪监测技术的基本原理,提出多级井间化学示踪动态监测技术,并进行了矿场应用。依据逐级调控设计方案及裂缝性特低渗透油藏水窜水淹特征,建立了多级井间化学示踪级次设计方法,优化了多级化学示踪剂筛选原则和用量计算公式,研究了裂缝性特低渗透油藏逐级调控示踪剂分类解释模型,形成了基于多级井间化学示踪的逐级调控参数优化预测方法。矿场应用结果表明:逐级调控多级井间化学示踪技术可有效反映裂缝参数动态变化规律,监测结果与矿场实际生产动态测试结果吻合,具有很好的适用性。图7表1参20

Abstract

To monitor the dynamic variations of sweep area and formation parameters during the process of multiple slugs step-by-step profile control, the multistage interwell chemical tracing technique was proposed and tested in field, in line with the features of the step-by-step profile control in fractured ultra-low permeability reservoirs and the basic principle of chemical tracing test. According to the design scheme of step-by-step profile control and the characteristics of water channeling and flooding in fractured ultra-low permeability reservoirs, this study worked out times-design method for interwell tracing, optimized the selection principle of chemical tracer and calculation formula of tracer dosage, and set up the parameter optimization forecasting method of step-by-step profile control based on multistage interwell tracing. The application results of the method show multistage interwell chemical tracing can reflect dynamic variation of fractured parameters effectively, and the monitoring results match with the dynamic production testing results, demonstrating good adaptability of the method.

Key words： fractured reservoir; ultra-low permeability reservoir; step-by-step profile control; multistage interwell tracing; dynamic monitoring
