松辽盆地十屋断陷天然气来源及成藏分析
Natural Gas Resource and Accumulation in the Shiwu Fault Depression, Songliao Basin
摘要
Abstract
In the Shiwu fault depression the major source rocks are the mudstones in Yingcheng Formation and Shahezi Formation, identified into two types: type Ⅱ kerogen and type Ⅲ kerogen. The isotopes and composition data of natural gas sampled from the Shiwu fault depression indicated complex origin of natural gas. Gas sources are different in different regions. In the Houwujiahu gas reservoir it was mixed origin of type Ⅱ and type Ⅲ kerogen with high mature and overmature degree, whereas in the Bawu and Siwujiazi gas reservoirs it was oil-type gas with normal mature degree and originated from type Ⅱ 1 kerogen. Natural gas was differentially accumulated in the Shiwu fault depression mainly due to the multi-phases charging of natural gas and fault activities. Natural gas reservoir has experienced several stages of accumulation and adjustment. In Houwujiahu field natural gas was accumulated mainly in late stage. In Bawu field the natural gas in shallow reservoir was accumulated in early stage with good preservation condition whereas in deep layers it experienced two stages. In Siwujiazi field the natural gas experienced two stages of accumulation and adjustment.关键词
