| 摘要: |
| 埕北断坡区具有优越的成藏地质背景,具有含油目的层多,油气藏类型多样,纵向叠置、平面连片的特点,油气勘探潜力巨大。通过对已发现油气藏的成藏要素剖析,认为充足的油气源、良好储集条件和储盖组合、基岩潜山背景下的断阶构造、长期继承性发育的断层、晚期成藏等是控制该区油气富集的主要因素。 |

| Abstract: |
| The Chengbei fault terraces are host to many target strata,where the oil and gas pools tend to be vertically stacked and laterally connected, and thus have great potential for oil and gas exploration.The main controlling factors for oil and gas accumulation in the study area include sufficient hydrocarbon sources,good reservoir-seal associations,fault terrace development,inherited fault development,later oil accumulation and diverse migration patterns for oil and gas. |
| Key words: accumulation oil and gas accumulation controlling factor Chengbei fault terraces |
