摘　　要：运用成藏动力系统的理论和方法,研究了二连盆地白音查干凹陷的成藏动力系统特征。白音查干凹陷划分为上、下2套成藏动力系统,下部高压自源半封闭成藏动力系统在南部缓坡带和北部陡坡带形成油气富集高产;上部低压混源半封闭成藏动力系统在南部缓坡带形成稠油富集。近几年,该区石油勘探连连突破,新增储量达数千万吨,是老凹陷油气风险勘探获得成功的佐证。This paper utilizes theory and method for dynamic system of hydrocarbon migration and accumulation to classify Baiyinchagan sag in Erlian basin into the upper and the lower systems.The lower one is high pressure-self source-half closed system which is oil-rich in the south ramp belt and north steep slop belt,and the upper one is low pressure-mixed source-half closed system which is oil-rich in the south ramp belt.In resent years,the breakthrough of petroleum exploration with several tens of million tons of incremental reserves in this area proves this theory and method can be successfully applied to the risk oil exploration of old sags.
