摘　　要：在东濮凹陷 ,洼陷的勘探有利目标应在烃源岩 ,中央隆起的勘探有利目标应在盖层之下。因为在洼陷处无断层、地层连续、油气横向运移 ,如遇有利圈闭即可聚集成藏 ;若有断层 ,则有可能向上运移至高部位 ,在圈、运、保三方面条件较好的地方聚集成藏。以主要接受前梨园洼陷 (区内最大的生油洼陷 )供油的白庙构造油气藏为例说明 ,生油岩是前梨园沙三3～ 4 地层 ,油气在邻近生油洼陷的前 8块中首先富集 ,然后顺断层向白庙构造高部造运移。正是这种运移成藏式作用 ,形成了白庙地区油气藏在构造高部位以中浅层富集为主 ,构造低部位以中深层油气藏分布为主的油气藏分布格局。In Dongpu sag and sub-depressions, favarate exploration target may exist in source rocks while in the Central uplift it may exist under the cap rock. There is no fault in the sub-depressions and the beds are successive, where hydrocarbon migrates laterally and may accumulate when favorable traps are encountered. If there are some faults, it may migrate upward to high part then accumulate at the places with good trapping, migrating and preserving conditions. Take Baimiao structural reservoir as example, it is mainly supplied by Qianliyuan sub-depression (the largest oil-generating sub-depression in this area), the 1source rock is Qianliyuan S3 3～4 interval, hydrocarbon may accumulate primarilyin Qian block 8 adjacent to oil-generating sub-depression, then migrate to high position of Baimiao structure along fault. For this migrating and reservoir forming action, the reservoir distribution pattern in Baimiao is formed: middle and shallow accumulation is dominant at the high part while middle and deep accumulation is dominant at the low.
