文安斜坡内带岩性地层油气藏勘探

Lithostratigraphic reservoir exploration inside Wen'an slope

结合霸县凹陷勘探实践,分析了文安斜坡内带深层岩性地层油气藏形成的有利条件,并对圈闭资源量进行了预测。研究表明,文安斜坡内带深层具有有利的沉积构造背景,紧邻生烃洼陷,储集砂体发育,以岩性地层圈闭为主的多种类型圈闭发育,是岩性地层油气藏发育的有利部位,具有较大的勘探潜力。

This paper addresses the favorable forming conditions of the lithostratigraphic reservoirs in the deep layers of Wen'an inner slope belt in Baxian Depression and predicts the volume of trap resources.The research shows that the deep layers in Wen'an inner slope belt has favorable structural setting,being close to hydrocarbon generation depression,has developed reservoir sands and various traps mainly involving lithostratigraphic traps,and has big exploration potential.
