摘要

英台断陷发育营城组一段火山岩岩性—构造气藏,营城组二段致密沉火山碎屑岩岩性气藏及登娄库组—泉头组砂岩气藏3种类型气藏。在分析气藏特征与成藏主控因素的基础上,指出了每种类型气藏的分布规律,并针对不同类型气藏分别采用特尔非法、容积法及地质分析类比法计算了天然气资源量。评价结果表明,英台断陷天然气总资源量为2 848×108m3,剩余资源量为2 228×108m3,占总资源量的78%,其中营城组二段的致密沉火山碎屑岩气藏资源探明率仅为18%,剩余资源潜力大,为下一步勘探的重要接替领域。

Abstract

There are three kinds of gas reservoirs in the Yingtai fault depression,southern Songliao Basin:Structure-lithology reservoir in the volcanic rock of the Yingcheng-1 Formation,lithology reservoir in the sedimentary pryoclastics rock of the Yingcheng-2 Formation and sand stone reservoir in the Denglouku-Quantou Formations.Based on analysis of the gas pool features and controlling factors,distribution of each kind has been studied.The resources of these gas reservoirs have been estimated by Delphi method,volumetric method and geological analytical analogy method,respectively.The results of the resources assessment show the total gas resources of the Yingtai fault depression is 284.8bcm,while the remaining is 222.8bcm,accounting for 78%.Especially,the exploration proven rate is only 18% for the lithology gas pool in the sedimentary pryoclastics rock of the Yingcheng-2 member,thus there will be great exploration potential in the future.
