徐深气田汪深1—达深3区块火山岩储层岩性岩相特征
|
摘要
松辽盆地徐深气田汪深1—达深3区块深层火山岩酸性、中基性都比较发育,岩性难于识别,岩相不易划分。在岩心观察、镜下鉴定和全岩分析进行火山岩岩性判别基础上,利用常规测井、电成像测井资料结合录井地震资料进行了全井段岩性识别。研究结果:识别出爆发相、溢流相、火山通道相和火山沉积相等4种火山岩岩相和11种亚相,亚相包括爆发相中的空落亚相、热碎屑流亚相、热基浪亚相,溢流相中的下部亚相、中部亚相、上部亚相,火山通道相中的火山颈亚相、次火山亚相、隐爆角砾亚相,火山沉积相中的再搬运亚相、含外碎屑亚相。
Both acidic and intermediate-basic volcanic rocks are highly developed in the deep blocks Wangshen-1 and Dashen-3 of the Xushen gas field,Songliao Basin,making it difficult to recognize lithologies and lithofacies.Lithologies of the volcanic rocks were identified through integrated core observation,thin section analysis and bulk rock analysis.On the basis of this,conventional log data,imaging log data,borehole log data and seismic data were integrated to recognize lithologies in the whole well interval.Four facies and 11 subfacies have been identified in the volcanic rocks.The 4 facies are eruptive facies,effusive facies,volcanic conduit facies,and volcanic sedimentation facies.And the 11 subfacies include pyroclastic fall deposits,pyroclastic-bearing lava flow and pyroclastic surge deposits of the erruptive facies;lower,middle and upper effusive subfacies of the effusive facies;volcanic neck,subvolcano and subtle eruptive breccias of the volcanic conduit facies;re-transportation and extraclast-bearing subfacies of the volcanic sedimentation facies.
