摘要
受钻井工程及地质等因素影响,常规油气检测技术录取的数据精度不确定性较大。通过对渤海油田大量的气测录井数据分析,建立了气相烃类衍生参数解构法,该方法包含基础数据的筛选与校正以及衍生参数的选取与解释等流程,通过把地层油气信息解构成烃组分单元,并找出烃组分及其衍生参数与储层特性的内在联系,从而建立储层流体解释、储层界面识别以及生物降解程度分析等方法,创立了烃类数据评价储层的新模式。渤海油田应用效果表明,本文方法解释结论与测井及测试结果吻合度较高,分析方便快捷,极大地提高了气测录井烃类数据评价储层的效果。
Data accuracy from conventional gas logging is unstable for some drilling engineering and geology factors. Through analyzing large amount of gas logging data in Bohai oilfield, the decomposition method of gaseous hydrocarbon derived parameters is established, which includes basic data screening and correction, derived parameter selection and interpretation. The formation hydrocarbon data is decomposed into hydro-carbon component, and the intrinsic relationship between hydrocarbon component, derived parameters and reservoir characteristics is examined. Therefore, such methods as formation fluid interpretation, reservoir interface identification and biodegradation degree analysis are established, thus building a new model of reservoir evaluation with hydrocarbon data. The application in Bohai oilfield shows that interpretation with new method agrees with logging and testing results. The method is convenient and can improve reservoir evaluation effect with gas logging hydrocarbon data.
