摘要：

采用井下化探综合评价与解释技术,提出了检验指标有效性的背景基准层和标志层的比拟衬托法、油气层预测中的概率分析法、油气叠加作用强度分析法和烃类气体浓度梯度法,评价油气层的派克斯勒图解法、三角图解法、轻烷烃比率法、D函数分析法。并建立了生油层、储集层(油层、气层)的化探异常模式。

关键词: 井下化探, 预测评价, 异常模式, 微渗漏行迹

Abstract:

By using synthetic assessment and interpretation of downhole geochemical exploration,this paper proposed following methods such as the analogy-foil method of both key horizon and marker horizon which could be used to check the effectiveness of geochemical exploration index; the probability analysis for oil and gas reservoir prospercting; the method to analyse hydrocarbon superimposition intensity and the density gradient of hydrocarbon gas; Paxle graphic method for hydrocarbon-bearing formation evaluationl triangular diagram;light alkane ratio;D-function analysis.According to the methods mentioned above,the model of geochemical exploration anomoly for hydrocarbon generation and reservoiring was established in this paper.
