摘要：

基于对俄罗斯远东鄂霍茨克海域内的北萨哈林盆地石油地质条件的分析和已发现油气田的解剖，总结了盆地油气分布特征，结合构造演化分析，对影响油气成藏及分布的主控因素进行了探讨。研究表明：北萨哈林盆地油气分布具有陆上储量规模小、海域陆架规模大的特点，在纵向上可以划分为两大成藏组合，但油气主要富集于达吉组和努托夫组。这两个主要含油气层已发现油气藏在平面分布上具有明显的分带性，靠陆内带以达吉组油气藏分布为主，远陆外带以努托夫组油气藏分布为主。油气富集受多旋回构造演化、富油气凹陷及构造活动差异性等控制，海域陆架裂后坳陷内的低幅度隆起构造区为高丰度大中型油气田聚集的主要有利区。

Abstract:

On the basis of the analysis of petroleum geological conditions and the known fields of the North Sakhalin basin in the Sea of Okhotsk, Russian Far East, the author summarized the oil and gas distribution features of the North Sakhalin basin, and then combining with the analysis of tectonic evolution, discussed the main controlling factors of hydrocarbon accumulation. The results show that the hydrocarbon distribution of this basin has the features that the scale of onshore reserves is much smaller than that of the sea shelf reserves, and it can be longitudinally divided into 2 large plays, however, the oil and gas are mainly enriched in the Dagi Formation and Nutovo Formation, which are obviously zonal in planar distribution, the Dagi Formation reservoirs are mainly distributed in the landward inner zone and the Notovo Formation reservoirs are mainly distributed in the outside zone far from land. The hydrocarbon accumulations are mainly controlled by multicycle tectonic evolutions, hydrocarbonrich depression and different intensity in tectonic activities. Low amplitude uplifted structure zones in the postrift depression of the sea shelf are the major favorable exploration targets for accumulation of high abundance mediumlarge oil-gas fields.

Key words: tectonic evolution, oil and gas distribution features, play, main controlling factors, Sakhalin, Russian Far East
