摘　　要：依据杨参1井和杨1井钻探成果及重磁电震资料，开展重磁电震联合反演，对大杨树盆地南部坳陷烃源岩的厚度及分布进行了预测。认为大杨树盆地南部坳陷具有良好的石油地质条件，下白垩统九峰山组上部和下部湖相泥岩是盆地主要烃源岩，分布在深坳陷中及其两侧断裂带附近的火山爆发相及火山沉积相是有利的油气储集相带，甘河组和九峰山组具有较好的生储盖组合。预测玉林屯凹陷为有利勘探区带，六合屯鼻状构造具有较好的油气成藏条件，是下步重点勘探目标。According to the drilling achievements and gravity, magnetic, electrical and seismic data from Wells Yangcan-1 and Yang-1, the combined evolution of the above data is conducted to predict the thickness and distribution of the hydrocarbon source rock in South Depression of Dayangshu Basin. The study shows that there are much better petroleum geology conditions in the depression, both the upper and lower lacustrine mudstones in Lower Cretaceous Jiufengshan Formation are the main hydrocarbon source rock of the basin, the volcanic erupted facies and volcanic sedimentary facies distributed in the depression and along the two sides of the fault belt are favorite petroleum enriched belts, Ganhe and Jiufengshan Formations are characterized by combination. Yulintun Sag is predicted more wonderful conditions of petroleum to be favorable exploratory play, and reservoir formation, so it will be the much better source-reservoir-cap rock moreover Liuhetun Nose is featured by future key exploration target.
