松辽盆地南部深层火山岩识别及成藏条件分析

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4.6×105m3/d的工业气流，推算无阻流量1.5×106m3/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。

Identifying of volcanic rock and analysis of hydrocarbon accumulation conditions in southern part of Songliao basin

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¡Á10ª¬5 mª¬3/d industrial gas flow after test from the volcanic formation. The openª²flow capacity is above 1.5¡Á10ª¬6 mª¬3/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 oilª²gas indication.ª¤
