摘要: 火山岩有效储集层主要分布在火山口-近火山口相带的有利亚相中。以松辽盆地 YX 地区营城组上部火山岩为例,综合利用反射强度属性、倾角属性、波形属性进行有效储集层预测。将反射强度弱、倾角值大和波形杂乱的区域划为有效储集层发育区;而反射强度强、倾角值小、波形连续的区域划为有效储集层不发育区;中间过渡区域有效储集层较发育。据此在研究区新识别出 23 个火山岩储集层有利目标区,为火山岩油气藏勘探提供了依据。

Abstract: Volcanic effective reservoir is mainly distributed in sub-facies of crater and near-crater zones. Taking the volcanic rocks of upper part of Yingcheng formation in YX area in Songliao basin as an example, these attributes such as single envelop reflecting reservoir porosity feature, dip angle reflecting volcanic edifice and waveform reflecting volcanic facies are utilized to predict the effective reservoir. The area of low single envelop, big dip angle and disorder reflection is classified into developed effective reservoir; the area of high single envelop, small dip angle and continuous waveform into undeveloped effective reservoir; the transition area into some effective reservoir. 23 favorable and target areas for forming the effective reservoirs are identified using this method as bases for further exploration of volcanic reservoirs in this area.

Key words: Songliao basin, volcanic edifice, volcanic facies, reservoir, seismic attribute
