油气真假显示判别是准确评价储层流体性质的前提和保证。该文从分析混油或加入有机添加剂对录井的影响因素入手,探讨了其对录井的影响程度,总结了地质、定量荧光、气测录井技术判别及消除假油气显示的方法,并对现场录井方法提出了具体要求,为今后准确评价储层流体性质提供了依据。
True or false oil and gas shows that discrimination is the premise and guarantee for accurate evaluation of reservoir fluid properties. This paper starts with the analysis of influencing factors on mud logging with mixed oil or adding organic additives, discusses its influence on mud logging, and summarizes the methods of geology, quantitative fluorescence and gas logging technology to discriminate and eliminate false oil gas display. Put forward specific requirements for on-site mud logging methods, and provided a basis for accurate evaluation of reservoir fluid properties in the future.
