摘要
混采油井分层产能的确定一般是通过生产测井或地层测试 ,但所需时间长 ,费用高。地球化学提供一种简便、经济、快速的确定分层产能技术 ,它是根据单层原油与混合原油的色谱指纹特征 ,配合室内不同比例人工配方实验 ,求得分层产能贡献。研究表明 ,实际配方与原油指纹计算的结果误差较小 ,两层的误差为 5%左右 ,3层的误差小于 7.0 % ,与生产测井的结果也较吻合 ,因此可用来计算混采油井的分层产能贡献 ,监测油层的工作情况。图 2表 2参 4(陈世加摘 )
Individual zone production allocation of the commingled oil wells is usually determined by production logging or formation test, but these methods need longer time and cost a lot. Reservoir geochemistry provides a simple and inexpensive technique which is based on oil fingerprint difference of individual zone and commingled oil, as well as artificial formulation, individual zone production allocation can be determined. The study shows that the difference between artificial formulation and oil fingerprint calculation is small, two zones <5.0%, three zones <5.0%, the result of oil fingerprint calculation is compared with production logging data, the difference is less than 10.0%, so the technique can be used to determine separate zone production allocation of commingled oil wells, and to monitor oil reservoir changes in production with time.
