Distribution of ancient ditches in Leikoupo Formation and its control over gas accumulations in Yuanba Gas Field

  • 摘要: 在详细论述元坝气田雷口坡组古溶沟形成条件、识别方法及展布特征的基础上,重点剖析了古溶沟对储层、圈闭、流体及油气富集区的影响,提出有利的勘探目标区。剥蚀作用、早期断裂及湿热气候控制了古溶沟的形成;溶沟区具有残留地层薄、上覆地层增厚及潜流带发育等特征,地震剖面上可见“下凹”及“双向上超”等现象。工区内发育4个主要溶沟区,单条溶沟宽度一般在2~3 km,切割深度为30~60 m;岩溶残丘地层保存较全,储集空间发育,为有利目标区。
