摘要： 从油气来源、输导体系、古构造演化等方面探讨白家海凸起成藏的主控因素。油气主要是源于二叠系烃源岩、侏罗系煤系烃源岩以及两者的混源；断裂、构造脊-砂体是其有利的输导体系；白家海凸起古构造高点在地质历史时期发生多次迁移和变迁，现在的油气藏主要沿古构造高点展布。烃源岩生、排烃时，处于开启状态的断裂和砂体为油气运移的优势通道，油气沿着此通道运移至古构造高点，后期的构造运动对古圈闭影响较小，因此，造成现今的油气藏沿古构造高点分布的特点。

Abstract: The control factors of petroleum accumulation in Baijiahai swell of Junggar basin are discussed in terms of oil/gas source, transport system and paleo?structural evolution, etc. The results show that the oil/gas source originated from the Permian hydrocarbon source rock, the Jurassic coal?measure source rock and both of them; the fault/fractures, structural ridge?sand body are as the favorable transport system; the multi?migration and changes occurred in its geological history period for the paleo?structural highs in this swell, and the reservoirs discovered nowadays are mainly distributed along these highs. When hydrocarbons in the source rocks were generated and expelled, the opened fractures and sand bodies became the preferred oil/gas migration pathways until the oil/gas entered into the paleo?highs. And the paleo?traps were seldom influenced by late tectonic movements. Therefore, the present reservoirs in this area are all characterized by their distributions along the paleo?highs
