西西伯利亚地台东南部古生界油气田成因与结构

Origin and Structure of Paleozoic Oil and Gas Fields in the Southeast of West Siberian Platformtranslated by Shang Zhenping

介绍了在西西伯利亚古生界寻找油气的简单历史，研究了形成优质储集层带和在其中形成油气藏的构造、岩性和物理化学等因素，建立了油气田的地质模型并对模型进行了描述。已查明该区古生界油气储集层主体位于侵蚀构造的高部位，无论是层状油气藏还是块状油气藏都具有岩性、构造和毛细管遮挡的复杂组合。古生界中的油气藏分布在志留系至下石炭统的范围内。

The paper briefly introduces the history of searching for oil and gas in Paleozoic in West Siberia which was first suggested by Academician A．A． Trofimok ． It deals with the factors which form the high quality reservoir zones and structures lithology and physical and chemical properties forming the oil and gas reservoirs． The authors established the geological models of oil and gas fields and described them ． It has been found out that the main body of oil and gas reservoirs in Paleozoic in this region is located on the highs of the etching structures． Both stratified reservoirs and fault block reservoirs are characterized by complicated combination of lithology structures and capillary barriers． Oil and gas reservoirs in Paleozoic formations are distributed ranging from Silurian to Lower Carboniferous．
