辽河坳陷兴隆台古潜山深部油藏地质特征及勘探意义

对辽河坳陷兴隆台古潜山储层特征、油藏分布特征、构造应力、成藏关键因素和成藏模式的分析和研究认为，兴隆台古潜山油藏可分为表生淋滤型和深部裂缝型古潜山油藏。表生淋滤型潜山油藏的储层形成与风化壳有关；深部裂缝型潜山油藏储层形成不仅与潜山岩性有关，还与区域应力场改变所形成的断裂有关，断裂带发育的部位是潜山储层裂缝最好的部位，而且断裂还是沟通油源与潜山圈闭的油气运移通道。此项研究对类似成藏条件的古潜山油气藏勘探具有一定的借鉴意义。

Geologic characteristics and exploration significance of Xinglongtai deep buried hill in Liaohe Depression, China

Analysis and study of Xinglongtai buried hill in Liaohe Depression in terms of reservoir characteristics,distribution,tectonic stress,key factors of oil accumulation,and reservoir forming pattern indicate that this buried hill reservoir can be classified into surface leaching reservoir and deep fractured reservoir.Surface leaching buried hill reservoir was related to weathering crust;deep fractured buried hill reservoir was not only related to buried hill lithology but also to the faults formed due to the change of regional stress field.The place where faults were well developed is the best fractured buried hill reservoir,and fractures also serve as oil and gas migration path from oil source to buried hill trap.This study provides a reference to oil and gas exploration in buried hills with similar reservoir forming conditions.
