| 摘 要： | 川东地区石炭纪的构造褶皱强烈,断裂发育,完整背斜很少,气藏一般赋存在背斜圈闭内。根据历年对川东石炭纪天然气的勘探所取得的大量地质、地震和测试资料分析,结合断裂、褶皱与储气层关系,本文对非背斜圈团气藏进行分类。这类圈闭在本区分布十分广泛,但其中以断层圈闭和地层-构造复合圈闭对天然气的聚集前景最好,其次为溶蚀岩性圈闭、岩性圈闭和残丘圈闭。

| Abstract: | In eastern Sichuan, Carboniferous strata are intensely folded and faulted, and complete anticlines are rare; so gas pools are generally non-anticlinal traps. Based on large amounts of geological , seismic and test data obtained through many years of Carboniferous gas exploration in eastern Sichuan, non-anticlinal trap gas pools have been classified and evaluated, and it is considered that oil pools of this type are widespread, of which fault traps and stratigraphic-structural composite traps are most promising, while lithologic, corrosion-lithologic and monadnock traps are less important. |
