Abstract: In the LN2 and 3 wellblocks of Lunnan oilfield in Tarim Basin,gas chromatographic analysis of oil from three Trassic reservoirs was used to evaluate vertical and lateral continuity within and between these reservoirs.The result was compared with early conclusion continuity.The method is helpful to understand the structure of the reservoirs,the oil field development,management programs for primary prodcuction,and also provide evidence for planning secondary and tertiary recovery programs thoroughly.

Key words: Lunnan Oilfield, reservoir, oil, gas chromatography

摘要： 塔里木盆地轮南油田三叠系原油是来自下古生界源岩的成熟海相原油,原油的物理性质和地球化学性质都十分相似,用总的特性很难区分不同油藏的原油.用原油气相色谱指纹法对轮南油田2、3井区三叠系油藏的连续性进行了研究,并与早期研究的结论进行了对比.结果表明,这种方法是评价油藏原油连续性的一种有效手段,它的应用有助于对油藏构造形态的深入了解,并能为油藏早期开发方案的设计提供辅助性依据.
