【摘要】 松辽盆地北部徐深1井在营城组火山岩获得油气突破后,在松辽盆地南部长岭断陷针对火山岩部署了长深1井。在长深1井营城组火山岩地层测试获4．6×105m3／d的工业气流,推算无阻流量1．5×106m3／d以上, 预示松辽盆地南部深层火山岩气藏是下步勘探开发的主要领域。通过大量的火山岩岩心资料,利用岩石学、矿物学、测井和地震地层学等多学科技术,首次在松辽盆地南部建立了火山岩识别标准,在东南隆起区部署探井1 口,在火山岩中见到了较好的气显示,取得很好的效果。更多还原

【Abstract】 After the breakthrough from the volcanic rocks of Yingcheng Formation in well Xushen 1, which locates in the north of Songliao basin, well Changshen 1 was deployed at Changling rift in the south of the basin, which yields 4. 6× 105 m3 /d industrial gas flow after test from the volcanic formation. The open-flow capacity is above 1. 5 × 106 m3 /d. The results indicate that the deep volcanic rocks maybe the next primary targets of exploration. We established a criterion for volcanic rock classification with multidisciplinary techniques such as mineralogy, petrology, well logging, and seismic stratigraphy. One exploratory well was drilled at the southern uplift, which yields good oil-gas indicatioa更多还原
