摘    要:确定油藏有效含油边界及预测油藏单井原油产能是储量评价和合理确定井位的基础。文中提出了一种用地球化学参数圈定油藏有效开采边界的方法。该方法中的地球化学参数是根据单井油层有效厚度和抽提物含量求出的 ,能反映单井的含油程度。该方法只需通过分析岩心或岩屑抽提物含量 ,结合少量井的试油成果 ,便可圈定出油层的合理经济开采下限范围。以松辽盆地新站油田为例介绍了这一方法的基本思路、参数选取、运算步骤及应用成效。

关 键 词:油藏地球化学  抽提物  油藏  含油边界

Abstract:To identify the effective boundary of oil reservoir and to predict potential production capacity in a single well are the foundation of reserves evaluation and drill_site selection. This paper has proposed a method that can identify effective recovery boundary of oil reservoir using geochemical parameters. These parameters may be drived from effective pay thickness in a single well and extractable hydrocarbon content of rock samples, and is capable of reflecting single_well oil abundance. Using this method, the recovery boundary with marginal economics can be identified for a reservoir only by analyzing core data or extractable hydrocarbon content and combining with a few well_testing data. With a case of Xinzhan Oilfield, Songliao Basin, the basic principles, parameter selection, calculation procedure and application results are discussed for the method.
Keywords:reservoir geochemistry  extract  reservoir  oil?bearing boundary
