摘　　要：辽河盆地红星地区在沙三中亚段发育的不同期次的火成岩储集层,在近年来出现了高产油流井。但由于该套储集层岩性致密坚硬,裂缝发育不均,且油质较轻,现场气测录井资料很难区分油水层,对以往的试油井资料进行分析也可以看出,该火成岩储集层的气测全烃值异常幅度与产能响应关系不明显,这给解释评价带来了很大的难度。为了提高解释符合率,从气测录井的烃组分和派生参数特征分析入手,通过研究该地区沙三段火成岩储集层的气测全烃值、组分含量、含油性特征与油气产能的关系,提出了基于火成岩气测录井相关参数C_2/C_3及其与W_h和B_h关系的解释标准,并在H-15、H-11等6口井的验证中取得成功,解释符合率达85%以上。该解释标准对红星地区火成岩油气层的解释评价具有一定的指导意义。High-yielding oil stream wells have been found in recent years in different stages of volcanic reservoirs developed in the middle part of the third member of Shahejie formation of Hongxing area in Liaohe Basin. However, it is difficult to distinguish the oil and water layers from field gas logging data due to the tight and hard lithology, uneven fracture development and light oiliness. The analysis of previous testing well data shows an unobvious relation between the anomalous magnitude of the total hydrocarbon value and productivity, which brings great difficulty to interpretation and evaluation. To improve the coincidence rate of interpretation, based on the analysis of hydrocarbon component and derived parameter characteristics of gas logging, by studying the relationship between total hydrocarbon value, component concentration, oil-bearing characteristics and oil and gas production capacity of the third member of Shahejie formation in the area, the relevant parameter C 2/C 3 based on volcanic gas logging and the interpretation standards of its relationship with W h and B h are proposed. It has been proved to be successful in six wells, such as H-15 and H-11 wells with coincidence rate over 85%. This interpretation standards have certain guiding significance for the interpretation and evaluation of volcanic reservoirs in Hongxing area.
