松辽盆地长岭凹陷深层气田成藏差异性及其成因
Study on reservoir forming difference and causes of deep gas field in Changling depression, Songliao basin
摘要
Abstract
Yaoyingtai deep gas field, Changling oil and gas field, Daerhan and Dabei gas reservoirs have been discovered in faulted layer of Songnan Changling depression, but there are obvious differences of gas compositions contents among each gas field. By studying on the gas carbon isotope, it was found that the gas source formed reservoir includes two kinds; organic hydrocarbon gas and inorganic mantle-derived CO2, also the maturities of organic hydrocarbon gas are different. On the basis of analysis on the difference of gas compositions, carbon isotope composition of different gas reservoirs, two aspects reservoir-forming stages and transport system are discussed for the reason of this difference. It is pointed out that the different reservoir-forming stages determined the difference of gas maturities and the different transport system determined the difference of gas compositions.关键词
