50多年来,许多研究者都在研究控制西西伯利亚含油气盆地油气分布的构造因素。М.Я.鲁德凯维奇、Ф.Г.古拉里、А.Э.库特罗维奇等曾对这一问题进行了详细研究。他们认为, 油田分布在新构造运动沉降区或很弱隆起区,而气田分布在较微弱的隆起带; 大型油气田分布与组成1级隆起的构造圈闭有关。长期稳定沉降的大型盆地和坳陷是生油气带; 原油聚集带分布在含油气盆地中部和较低部位, 天然气聚集带分布在盆地边缘。西西伯利亚含油气省共有巨型和大型油气田249个, 其油气储量占了含油气省总储量的90%以上。将西西伯利亚含油气省划分为3个区域性大地构造单元: 外带、亚马尔半岛- 喀拉区域沉降带和鄂毕区域阶地。后两个构造单元组成了台向斜的内带。在这些构造单元中分布着大型和巨型油气田。详细研究了这3个大地构造单元的巨型和大型油气田及其储量。
For more than 50 years, many researchers are studying the structural factors controlling the oil and gas distribution in the western Siberia petroliferous basins. М.Я. Ludkiewicz, Ф.Г. Góra, А.Э. Kutrovich et al. Conducted a detailed study of this issue. They think that the oil fields are distributed in the neotectonic movement subsidence area or the weak uplift area, and the gas field is distributed in the weaker uplift belt. The distribution of large oil and gas fields is related to the tectonic traps that constitute the first grade uplift. Large-scale long-term stable settlement of the basin and depression is a raw oil and gas zone; crude oil accumulation zone distributes in the central and lower part of the petroliferous basin, natural gas accumulation zone distribution in the basin edge. There are 249 giant and large oil and gas fields in the West Siberia oil and gas province, accounting for more than 90% of the total oil and gas province reserves. The West Siberia hydrocarbon-bearing province is divided into three regional geotectonic units: the outer belt, the subsidence zone of the Yamal Peninsula-Kala region and the terraces of the Obi region. The last two tectonic units make up the syncline belt. Large and giant fields are distributed in these tectonic units. The giant and large oil and gas fields and their reserves of these three tectonic units are studied in detail.
