应用油藏地球化学原理，从研究油藏烃类流体非均质性入手，分析了烃类的运移效应，充注期次、方向和顺序认为（１）凹陷内存在有两类来自同一烃源岩在不同热演化阶段排烃、聚集而形成的不同成熟度的原油；（２）两类原油具有不同的运移效应，是两期烃类充注作用的结果；（３）达尔其构造油藏中的烃类注入方向自北向南，其中白音断层上升盘达３、６井原油是早期流体运移的产物，而下降盘达１、２、３井等原油则是晚期烃类充注作用的结果．
Based on the reservoir geochemistry principle, starting from the study of hydrocarbon fluid heterogeneity, the migration effects, filling times, directions and order of hydrocarbons are analyzed. (1) (2) the two types of crude oil have different migration effects and are the result of hydrocarbon charging in the two phases; (3) the structure of Dahleqi The hydrocarbons in the reservoir are injected from north to south, of which crude oil from Well Baiyin uplift reaches 3,6 was the product of early fluid migration, whereas the crude oil from wells up to wells No. 1, Note the effect of the results.
