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 )
Stratified production capacity of mixed oil wells is generally determined through production logging or formation testing, but the time required is high and the cost is high. Geochemistry provides a simple, economical and rapid method of determining stratified production capacity. It is based on the chromatographic fingerprints of single-layer crude oil and mixed crude oil, with laboratory experiments of different proportions in the laboratory to obtain the contribution of stratified capacity. The results show that the error between the actual formulation and the crude oil fingerprinting is small, the error between the two layers is about 5%, the error between the three layers is less than 7.0%, which is in good agreement with the result of production logging. Therefore, Layered production capacity contribution, monitoring the work of the reservoir. Figure 2 Table 2 Participation 4 (Chen Shijie picking)
