伊通盆地储集层解释评价方法及应用

针对吉林探区伊通盆地储集层地质条件复杂、难以评价的问题,通过对该盆地储集层气测录井参数进行深入分析,筛选出适合储集层评价的气测优势参数,建立了适用于该盆地储集层评价的气测录井解释评价方法———甲烷与全烃法、甲烷与全烃峰基比法、气测全烃曲线形态法、气体比值法。在此基础上,利用岩石热解地化分析中的含油气总量参数,分别建立了与气测全烃和甲烷对应评价图板。应用这些方法解决了该盆地粗碎屑岩低显示和细碎屑岩高显示储集层油气评价的难题,提高了储集层录井评价水平,解释符合率由71%提高到85%以上,为油气勘探开发提供了技术支持,对其他盆地类似储集层的油气评价有一定的借鉴作用。

Reservoir interpretation and evaluation method and its application for Yitong Basin

In view of the problem that the geologic condition is complex and evaluation is difficult for the reservoirs in Yitong Basin of Jilin exploration area,and through making further analysis of gas logging parameters of reservoirs in Yitong Basin,the dominant gas logging parameters were screened out,which are suitable for reservoir evaluation,and the gas logging interpretation and evaluation methods were set up,which are applicable to reservoir evaluation in Yitong Basin,that is,the method of methane and total ...
