摘要: 为了明确准噶尔盆地环东道海子凹陷侏罗系煤层气勘探方向,开展了煤层连井对比、井-震标定和地震资料解释以及煤层测、录井资料分析。研究结果表明:①准噶尔盆地侏罗系西山窑组和八道湾组煤层发育,厚度较大,分布稳定,其中西山窑组发育2~3层煤层,累计最大厚度为20 m,八道湾组发育2~4层煤层,累计最大厚度为29 m。煤岩含气性好,录井气测异常明显。②环东道海子凹陷内中下侏罗统煤系烃源岩为中等—好烃源岩,Ro为0.6%~0.8%,处于低成熟—成熟阶段,具有较好的生气能力;天然气碳同位素分析结果显示,煤层气亦可来源于深部高成熟腐殖型有机质。③研究区西山窑组煤岩为中—低孔、低渗储层,孔隙度为7.0%~20.8%,渗透率为0.32~8.67 mD;八道湾组煤岩为低孔、中—低渗储层,孔隙度为5.6%~7.8%,渗透率为2.30~13.83 mD;煤层夹于泥岩之间且煤层之上区域性泥岩盖层分布广泛,封盖保存条件好。④研究区存在凹陷区源内煤层气富集成藏和凸起区深部外源气富集成藏等2种模式。环东道海子凹陷煤层气勘探潜力较大,特别是凹陷北东方向斜坡区和凹陷北部斜坡—滴南凸起区。
