摘　　要：现场录井油气显示落实和岩性识别是两个技术难点也是重点。特别是在辽河外围盆地,油层存在气测值较低未见明显异常,且分布不稳定的特点;区域岩性复杂,特殊岩性居多,邻井远且被断层隔开,岩性的落实难度大的特点。因此对录井施工过程中油气显示的落实和岩性识别提出较高要求。运用现场的录井经验,综合地化录井、元素录井、定量荧光录井以及薄片分析和扫描成像技术,通过这些先进的特色录井技术来证明,进而反向回推,为现场油气显示和岩性的落实提供依据。The implementation of on-site logging and oil-gas display and lithology identification are two technical difficulties and priorities.Especially in the Liaohe Peripheral Basin,there is no obvious anomaly in the oil layer and the distribution is not stable.The regional lithology is complex,the special lithology is mostly,the adjacent well is far and separated by the fault,and the lithology is difficult to implement.Great features.Therefore,higher requirements have been put forward for the implementation of oil and gas displays and lithologic identification during the construction of mud logging.Using on-site mud logging experience,comprehensive geochemical logging,elemental logging,quantitative fluorescence logging,and slice analysis and scanning imaging technology have been proven through these advanced and characteristic logging techniques.Reverse pushback provides the basis for the on-site oil and gas display and the implementation of lithology.
