摘　　要：长庆油田是典型的具有"低渗、低压、低丰度"特点的"三低"油气藏。近年来,随着勘探领域不断深入,勘探难度越来越大,部分探区油气成藏复杂,油水关系识别难度大。为了有效勘探开发致密油气藏,加速在新区、新领域寻找新发现、获得突破,针对性地开展了录井检测技术的创新研究,长庆油田2007年首次将红外光谱分析技术引入勘探领域,于2011年在长庆油田全面推广应用。介绍了红外光谱技术的基本原理、关键技术及实现方法、录井中的评价方法研究、与传统色谱技术性能对比等,通过170余口各类油气探井的现在试用验证,该技术分析速度快,更有利于薄差油气层的识别,且参数丰富,仪器性能稳定可靠,显示了其技术优势,录井综合解释符合率由61.5%提高到81.8%。结合实例阐述红外光谱的气体录井技术在长庆油田的应用效果及前景展望。Changqing Oilfield is a typical '3 low' oil and gas reservoir with the features of low permeability,low-pressure and low-abundance.In recent years,with the deepening exploration areas,the exploration difficulty is growing,hydrocarbon accumulation is complex and the recognition of the oil-water relationship is difficult in part of the exploration areas.Effectively explore and develop tight oil and gas reservoirs,and search for new discoveries in the new areas to obtain a breakthrough,all these put forward higher requirements on mud logging technology.To promote the development of mud logging technology in low-permeability oil and gas field,in 2007 Changqing Oilfield introduced the infrared spectroscopy technology for the first time into the exploration fields,which lasted more than three years of field trials to obtain better results.In 2011 the application of the technology was promoted in Changqing Oilfield.The paper introduced the infrared spectroscopy's technology and its basic principles,key technologies and implementation methods,evaluation methods and research in mud logging,technical performance comparison with conventional chromatography and clarified the effects and prospects of the application of infrared spectra of gas logging technique in Changqing Oilfield combining with the practical examples.
