摘要

白音查干凹陷的油气藏主要分布于下白垩统巴彦花群腾格尔组中、上部

稠油油藏在成油门限之上

稀油油藏在成油门限之下。油藏类型主要有 :(1)逆牵引背斜油藏;(2)披覆背斜油藏;(3)断块、断鼻油藏。油气藏的类型和规模受控于生油洼陷、区域生储盖组合、背斜构造或早期形成的断块构造以及沉积相带或砂体类型。

Abstract

Oil-gas pools of Baiyinchagan Depression are principally distributed in the Middle and Upper parts of Tenggar Formation of Bayanhua Group

Lower Cretaceous.The reservoirs of thick oil is above the oil generation threshold

thin oil is below that.There main oil-gas pool types of the depression are:(1)the reverse drag-anticlin oil pools;(2)drape-anticlin oil pools;(3)fault-block and fault-nose oil pools.The pool types and scales are controlled by oil source sag

regional source-reservoir-cap rock complex

anticlinal structures or fault-blocks and sedimentary facies or sandbody types.
