摘要
根据热采井产出流体变化与油藏动态变化规律,利用产出流体组分变化监测杜84块油藏动态.其一,利用产出液中氯离子及总矿化度的变化,判断生产井中产出水的来源;其二,产出液离子变化,判断注汽过程中是否发生汽窜;其三,产出液离子含量变化,判断注汽井补层效果;其四,生产井气组分分析,判断井间连通情况及注气受效情况.在不关井、不作业、不下井下测试工具的情况下,不需要额外注入任何化学药剂,只是利用对注入井的注入流体和生产井的产出流体中化学成份的分析来实现生产动态监测.
The thesis demonstrates that analysis of chemical components of the produced fluid is an effective approach to achieve dynamic production monitoring. The variations of output fluid indicate the dynamic changes of reservoir in thermal recovery well Du-84wells, the dynamic changes of the reservoir is thereby monitored. First, the production well gas components are analyzed to determine well correlation of the wells and the efficiency of gas injection. Without shut-in, operation, or utilizing downhole testing tools, and additional chemical injection, only analyzing the injected fluid and production fluid can determine the origin of water in produced fluid by analyzing the chloride ions and total mineralization in the production fluids; Second, changes of the output liquid ions can determine whether Steam channeling has occurred during steam injection; Third, ion content changes in the output fluid are employed to determine the effect of injection well layering.
