松南盆地长岭凹陷腰英台区块断裂构造及储层特征

根据最新的三维地震解释成果和钻探资料,分析了松辽盆地南部长岭凹陷腰英台区块断裂构造特征。根据物性和岩矿报告,分析了该区块储层特征。腰英台圈闭群是由多组走向近南北向的正断层分割成不同的构造,即西部的斜坡带、中部的地堑和东部的地垒,各构造带内又被次级断层分割成不同的构造。腰英台区块主要含油层系为泉头组顶部、姚家组和青山口组砂岩;储层样品平均渗透率为3.1 8×1 0 ^-3 μm² ,平均孔隙度为13.13% ,平均含油饱和度为1 8.80 % ,平均含水饱和度为20 .2 4 %。在腰英台区块,泉头组、姚家组和青山口组地层走向近南北向,倾向近西,地层倾角4°～8°左右,整体呈现向东部一直抬高的缓坡单斜形态。

THE RUPTURE STRUCTURE AND RESERVOIR CHARACTER IN SOUTH SONGLIAO BASIN IN CHANGLING SAG YAOYINGTAI AREA

On according the newest three earthquake preserve explaining fruit and drilling data of South Songliao basin in Yaoyingtai Changling sag area, analysis the rupture structure character. On according analyse report of character and rock mine, analysis reservoir character.
