摘要
由于地化录井对取样对象及分析条件要求较高,因而对轻质油层、凝析油层等级别显示较低的地层的解释评价符合率相对较低。通过对印尼区块的含油特点和操作上的延时性分析了显示较低的原因,阐明了烃类比值法识别这类储集层的理论,提出了地化录井识别和评价这类储集层的方法———比值法和剖面法,有效地解决了该类地层解释符合率较低的问题。
Geochemical logging has a high requirement for sampling object and analysis condition, so it has low accordance percentage of interpretation and evaluation for light oil reservoirs and condensate oil reservoirs which have poor shows. This paper analyzes the cause of poor shows basing on the oil-bearing characteristics of Indonesia block and the time delay property of operation, illustrates the theory of identifying this type of reservoirs using hydrocarbon ratio method, and proposes ratio method and profile method for identifying and evaluating this type of reservoirs using geochemical logging.
