摘要
以往应用饱和烃气相色谱资料判断储集层产液性质,主要是根据谱图特征进行人为判断,受人的影响因素多。从对原始资料处理出发,通过对饱和烃气相色谱资料表征处理,直接给出数据,解决了气相色谱原始分析数据转换和存储难题,为该项资料的定量化应用奠定了基础。通过从处理参数中优选评价油水层的特征参数,将反映图形特征与反映含油性特征的参数结合,建立了油水层解释评价图板,提出了求取饱和烃气相色谱含水性评价指数(Fwqx)方法,不但对储集层的产液性质进行判断,而且通过含水性评价指数的大小,对油水层的油水产出比例给出了一个相对值,为储集层油水产出比例解释评价提供数字化依据,使该项资料的解释达到了定量化。目前,该方法已在生产中全面推广应用。
Previous application of saturated hydrocarbons gas chromatography data to determine the nature of reservoir fluid production was mainly judged by manual based on the spectral characteristics,which was influenced by man factor at large extent.Starting from the raw data processing,by processing characterization for the saturated hydrocarbon gas chromatographic information,the data can be read directly,which has solved the problem of the conversion and storage of the original analysis data of the gas chromatography,thus providing the foundation for the quantitative application of the data.By the optimization and evaluation of the characterization parameters for the water layer from the processed parameters,and by combination of the parameters reflecting the graphical features with that reflecting oil-bearing characteristics,the interpretation and evaluation chart for oil and water has been established,and the extracting method for water-bearing property evaluating index of the saturated hydrocarbons gas chromatography is put forward.Not only can the reservoir fluid productive properties be judged,but also can a relative value be given about the oil and water output proportion in the oil and water layers according to the water bearing evaluating index,which provides the digital basis for the interpretation and evaluation of reservoir oil and water output ratio,thus making the data interpretation quantitative.At present,the method has been applied in the production.
