摘要

泌阳凹陷浅层原油和中等深度原油均来自中等深度的生油岩

前者以向上运移为主

后者以短距离侧向运移为主。埋藏较深的原油来自深部生油岩

以较长距离侧向运移为主。

Abstract

Based on the data of steranes and terpanes of 17 source rock samples and 6 crude oil samples collected from Biyang depression

Nanxiang Basin

the authors considered that crude oil produced from middle-depth reservoirs or reservoirs buried shallower than threshold-depth(2100m)were migrated from middle depth source rocks.But the former is mainly in a state of lateral migration within a short distance;while the later is upwards primarily.Crude oil buried in a greater depth was generated from much more deeper source rocks

and bound to migrate for a long distance.
