摘　　要：为了研究海拉尔盆地苏德尔特地区下白垩统大磨拐河组油气分布规律,在深层油气“中转站”(所谓油气中转站是源岩内和外已聚集的油气分布区,可为浅层油气成藏提供油气来源)中转油气机理及有利部位研究预测方法的基础上,通过确定下白垩统南屯组油气中转站分布区和南屯组顶部泥岩盖层不封闭区,确定南屯组油气中转站向大磨拐河组中转油气分布区,结合输导断裂输导油气有利部位,利用本文所建立的深层油气中转站向浅层中转油气有利部位预测方法,对苏德尔特地区南屯组油气中转站向大磨拐河组中转油气有利部位进行了预测,结果表明:苏德尔特地区南屯组油气中转站向大磨拐河组中转油气有利部位主要分布在其中部地区,少量分布在其西北和东北部地区,控制着苏德尔特地区大磨拐河组油气成藏与分布,南屯组油气中转站向大磨拐河组中转油气有利部位处或附近尚未钻探部位应是该区大磨拐河组下一步油气勘探的有利部位。In order to study the oil and gas distribution of the Lower Cretaceous Damoguaihe Formation in Sudeerte area, Hailar Basin, on the basis of the mechanism of oil and gas transfer in deep oil and gas “transfer station” and the prediction method of favorable position. By determining the distribution area of oil and gas “transfer station” in the Lower Cretaceous Nantun Formation and the unsealed area of mudstone cap rock at the top of the Nantun Formation, the oil and gas “transfer station” from the Nantun Formation to the Damoguaihe Formation is determined. Combined with transporting fault transporting oil and gas favorable position, this paper uses the prediction method of favorable position of oil and gas transfer from deep oil and gas “transfer station” to shallow oil and gas, the favorable position of oil and gas transfer from the Nantun Formation to the Damoguaihe Formation in Sudeerte area is predicted. The results show that: The favorable parts for oil and gas transfer from the Nantun Formation to the Damoguaihe Formation in Sudeerte area are mainly distributed in the central area, and small amounts are distributed in the northwest and northeast regions, which controls the oil and gas accumulation and distribution of the Damoguaihe Formation in Sudeerte area. The favorable position of oil and gas transfer from the Nantun Formation to the Damoguaihe Formation or the undrilled position nearby should be the favorable position for the next oil and gas exploration of the Damoguaihe Formation in this area at present.
