摘要
针对气测录井常用的解释评价方法存在的纯气层、油水或气水同层、水层难以识别的不足,该文提出了一种新的油气层解释评价方法C2/C3烃比值法。文章介绍了该方法的解释评价标准。通过QMQ潜山奥陶系6口井的试用,证实该方法恰好适合此类储层解释评价,用此方法评价油气层具有准确、快捷和方便的特点,而且还能从纵向上对储层的优劣和产能的高低进行评价。这对不同地区、不同地层、不同岩性摸索、优选一种有效解释评价方法具有一定的指导意义。
In order to easily diagnose net gas zone,oil-water or gas-water same layer and water layer,the paper provides a new hydrocarbon interpretation and evaluation method C_2 /C_3 hydrocarbon ratio technique,introduces the interpretation and evaluation criterion of this technique.Through testing 6 wells in QMQ Buried Hill Ordovician System,this technique is verified to be suitable to the cases of such reservoir productivity evaluation and interpretation.This technique not only has accurate,fast and convenient features,but also has thr feature of evaluating good and bad reservoir and the amount of productivity from vertical orientation.It has a certain guiding meaning for different areas,different formations and different lithology to find out and optimize an effective interpretation and evaluation method.
