摘　　要：塔河油田奥陶系碳酸盐岩储层非均质性强、储集空间类型复杂多样,储层中流体性质的识别比较困难。在利用测井资料划分储集空间类型的基础上,结合试油资料对不同储集空间类型的油水层的气测值进行统计,讨论不同储集空间类型中油水层气测响应特征。研究表明,流体性质相同储集空间类型不同的储层,其全烃及组分绝对含量的分布范围、异常幅度和组分的齐全程度也不相同。这些结果为在测井资料划分储层类型的基础上利用气测资料识别流体性质提供了依据。In Ordovician carbonate reservoirs of Tahe Oilfield,the reservoir heterogeneity was strong,its space was complex and variable and reservoir fluid identification was difficult.On the basis of reservoir space identification by using logging data and in combination with formation test data,the gas logging value of oil-water layers with different reservoir spaces was discussed,the response characteristics of the gas logging in oil-water layers in different reservoir spaces were discussed.The study shows that the reservoirs with the same fluid property and different reservoir spaces,the distributive range of the total hydrocarbon and its components and extent of gas abnormal characteristics were different.These results provide the basis for fluid property identification by gas logging on the basis of known reservoir space type.
