摘　　要：转动系统中的油气质点总是要朝着能使自身转动惯量减少的方向移动 ,地球的自转促使油气质点向两极移动 ,地球的公转促使油气质点向北极移动。油气质点的运动具有科里奥里效应。北半球生油凹陷的油气 ,按照顺时针的形式向其周围提供油气 ,最优先获得油气的部位为凹陷的北东方向紧邻的部位 ,而南半球生油凹陷的油气 ,则按照逆时针的形式向其周围提供油气 ,最优先获得油气的部位为凹陷的西北方向紧邻的部位。我国准噶尔盆地盆 1井西凹陷北石西油田、玛湖凹陷北玛北油田等 ,塔里木盆地满加尔凹陷轮南油田、库车凹陷北依奇克里克油田等实际资料印证了这一论点。In the turn-round system, hydrocarbon particles always tend to move to the directions where their turning inertia becomes less. The rotation of the Earth will force hydrocarbon particles to move towards the South Pole and the North Pole, while the revolution of the Earth will make hydrocarbon particles move towards the North Pole. Meanwhile, Coriolis effect will influence the movement of hydrocarbon particles. Oil and gas from the hydrocarbon-generating depressions are distributed around depressions in clockwise direction on the Northern Hemisphere. And oil and gas from the hydrocarbon-generating depressions are distributed around depressions in anticlockwise direction on the Southern Hemisphere. The above conclusion is proved by examples from, among others, the Sixi and Mabei oilfields of Junggar basin, Manjia'er and Yiqikelike oilfields of Tarim basin.
