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. |
