摘　　要：歧口凹陷与车镇凹陷以埕宁隆起相隔。由于构造背景和演化不同,致使歧口凹陷成烃演化、沉积条件、油气藏类型与车镇凹陷存在差异。歧口凹陷长期继承发育,晚期断裂活动强烈、有机质演化程度高、是其多层系含油气的主要原因。歧口凹陷与车镇凹陷存在的成藏条件差异表明,歧口凹陷具有形成巨型、大型油气田的条件,文章认为目前勘探方向应该以北西向调节带和泥岩裂缝油气藏为目标。Qikou sag and Chezhen sag are separated by Chegning uplift.The hydrocarbon generation,deposition condition,reservoir type are different between two sags,since they are located on different tectonic setting and evolution.Long inheritance,active late fault and high organic evolution degree are the main reasons to multiple strata reservoir.The differences of reservoir formation conditions and distribution between Qikou sag and Chezhen sag demonstrate that Qikou sag is full of the conditions to form large oil and gas field,and the exploration objects should be predominantly NW accommodation zone and mud-fractured hydrocarbon reservoir.
