摘要
与传统意义上的气测录井系统相比,FLAIR气测录井系统的烃类气体检测分析不仅包括C_1—C_5,而且扩展到nC_6、nC_7、nC_8、C_6H_6、C_7H_8和C_7H_(11),烃类气体检测能力的提高.为研究"重组分"在油、气、水层解释评价中的规律奠定了基础。从这一角度出发.以该系统在渤海和南海油田几口井的应用实践为例,通过"重组分"数据特征的统计分析,提出了依据"重组分"快速识别油、气、水层的原则与方法。实际应用表明,该方法简便、可行,可作为现场快速评价油、气、水层的一种有效辅助手段。由于至今未在气井钻探中应用FLAIR,该方法对于水层和气层的识别尚无明确的界定原则。
Compared with traditional gas logging system,the de- tecting analysis for hydrocarbon gases by FLAIR gas log- ging system not only includes C_1-C_5,but expands to nC_6, nC_7,nC_8,C_6H_6,C_7H_8 and C_7H_(14).The improvement of detecting level for hydrocarbon gases laid the foundation for studying the rules of'heavier components'in the interpre- tation and evaluation of oil,gas and water layers.In view of this aspect,taking the application practice experienced by the system for a number of wells in Bohai Sea and South China Sea as the examples,the author put forward the prin- ciple and method for fast distinguishing oil,gas and water layers in accordance with'heavier components'by analyti- cal statistic for the data characteristics of'heavier compo- nents'.It was showed by practical application that the method was simple,feasible and can be taken as an effective auxiliary means for fast evaluating oil,gas and water lay- ers.As FLAIR has not been used in gas well drilling,there is no clear dividing law in distinguishing water layer and gas layer for the method.
