| 摘 要： | 根据油气成藏的基本要素对准噶尔盆地滴北1井区油气成藏条件进行了分析,并在此基础上总结出该井区的油气成藏模式.研究结果表明:滴北1井区主要的烃源岩为石炭系滴水泉组暗色泥岩;该井区储集层发育,共有4套储盖组合;主要为构造圈闭,具有良好的运移和保存条件.该井区共有2期油气成藏过程:一是三叠纪末—中侏罗纪,石炭系烃源岩生成的低熟油气在上部的侏罗系和三叠系地层中聚集形成早期油气藏,但由于后期构造活动,早期形成的油气藏被破坏,油气散失,形成沥青残留物;二是白垩纪—现今,石炭系烃源岩生成的大量成熟—高成熟油气在上部地层中聚集形成现今的油气藏.

| Abstract: | The hydrocarbon accumulation conditions in Dibei 1 wellblock of Junggar Basin are analyzed according to the basic factors of forming oil-gas reservoir,and the oil-gas reservoir forming modes in the wellblock are summarized.It is shown that,the main hydrocarbon source rock in the wellblock is the dark mudstone of Dishuiquan Formation of Carboniferous,and there are 4 sets of reservoir-cap rock assemblages.The main trap type is structural trap,and the traps have good migration and conservation conditions.There... |
