摘    要:混采油井分层产能的确定通常用生产测井,分层测试及示踪剂跟踪方法,但它们成本高,周期长,对窜层油井不适用,且对流速低和窜层油井不适用,有时还需在关井停产条件下进行,作业过程中还易伤害油层。介绍了一种产能监测的新方法-原油色谱指纹法,利用单层原油色谱批纹差异及井口混合原油的指纹变化特征,配合室内原油配方实验,求得混采井分层产能贡献,研究表明,不同类型不同比例二元及三元原油配方与指纹计算的误差在10%以内,指纹计算结果与生产测井的误差在15%以上,可用来计算混采油井分层产能贡献,监测油层出力情况。

关 键 词:混采油井 原油色谱批纹法 配方 实验 产能监测

Abstract:Commonly used methods of production allocation of multi?zones commingled wells in oil field include production logging, separate test and tracer logging. These methods however are expensive, time?consuming, and not applicable for low rate reservoirs. In this paper, oil chromatographic fingerprinting technique is introduced. The method is based on the difference of oil fingerprints for individual zones and the fingerprint variations of commingled oils. Laboratory artificial formulation is conducted to "match" the observed variations. With the best match obtained, individual zone production can be directly allocated. Results show that the difference between artificial formulation and oil chromatographic fingerprinting calculation is less than 10% for two?zones commingled oil well, and the difference between oil fingerprints calculation and production logging is less than 15%. With the proposed method, production allocation of commingled oil wells could be made faster, cheaper and simpler.
Keywords:commingled oil wells  production allocation  oil chromatographic fingerprinting  formulation experiment
