大港油田关家堡地区不同含油层系气测解释方法探讨

大港油田关家堡地区油气藏特征复杂，不同含油层系油气显示特征不同，气测录井解释符合率相对较低。针对这一情况，通过分析关家堡地区明化镇组、馆陶组和沙河街组的地质和气测显示特征，结合试油结论，提出不同含油层系相应的气测录井解释方法——TR与Wh（湿度比）气测解释法和三角形图板法，归纳总结了全烃及组分在不同层系的变化规律。应用实例表明，效果较好，对于复杂油气藏多层系油气层的解释评价具有一定的借鉴作用。

Discussion about gas logging interpretation methods of the different oil-bearing layer series for Guanjiapu area of Dagang Oilfield

The features of Guanjiapu reservoir in Dagang Oilfield are complex,so the features of oil and gas shows from dif- ferent oil-bearing series are different,and the gas logging interpretation coincidence rate is relatively low.In view of this situation,by analyzing geological and gas logging show features of Minghuazhen,Guantao and Shahejie groups of Guanjiapu area,combining with oil testing results,the pa- per put forward the gas logging interpretation methods of T_g & W_h (humidity ratio) and triangle chart,which corre- sponded to the different oil-bearing layer series,and it also summed up the laws of total hydrocarbon and component variations from the different layer series.The applied re- suits indicated these methods were good,and they had a certain reference functions for oil-gas layer interpretation and evaluation to the multiple layer series of the complex hydrocarbon reservoir.
