摘　　要：栗园地区是河南油田近两年来老区精细勘探取得突破的一个地区,为解决该区录井含油级别偏低、气测绝对值偏低、气测组分不全及地化分析数据受岩性影响所带来的解释难题,在分析该区油气显示特点的基础上,针对气测全烃异常相对幅度明显、地化录井油层段显示相对较好的优势,提出利用气测全烃曲线形态识别储集层流体性质的方法并建立了气测全烃相对幅度与灌满系数解释图板、地化B-P解释图板。经B315井实际应用,证实这些图板有较好的实用价值,表明录井技术在栗园地区油气发现与评价中有着重要作用,常规地质录井、气测录井、地化录井技术相互结合能够准确发现与评价油气层。Liyuan is one of areas in which a breakthrough has been made during the fine exploration in Henan Oilfield in recent two years.In order to solve the interpretation problems of the area which were brought from low oil bearing level in mud logging,relative low value in gas logging,incomplete components in gas logging and geochemical data influenced by lithology,on the basis of analyzing characteristics of gas and show of the area,in view of the advantages of the relative obvious range for total hydrocarbon of gas logging and the relative better oil and gas shows in the geochemical logging well intervals,the authors provide the method of distinguishing reservoir fluid properties by using total hydrocarbon curve form of gas logging,establishes the interpretation chart of the relative range of gas logging total hydrocarbon and filling up coefficient and the geochemical B-P interpretation chart.It was verified by the practical application in Well B 315 that these charts have better using value and the logging technology plays an important role in discovery and evaluation of oil and gas in Liyan area,and the inter combination of conventional geologic logging with gas logging and geochemical logging technology can discover and evaluate oil and gas zones accurately.
