摘要:
以川东南盆缘复杂构造区南川地区为研究对象,基于钻井、实验分析测试等资料,开展深层页岩气富集特征研究,重点讨论地层温度、地层压力等成藏环境变化对深层页岩气富集的影响作用。研究认为:①优势沉积相带是页岩气藏成烃的基础,研究区五峰组—龙马溪组一段形成于深水陆棚沉积环境,优质页岩发育,具备形成页岩气藏的良好物质条件。②有机碳含量控制纳米级有机质孔隙的发育程度,高压—超高压环境有利于孔隙的保持,对改善深层页岩物性发挥积极作用。③深层页岩气具有高温、高地应力的典型地质特征。温度较压力对页岩吸附能力的影响更为明显,深层页岩气赋存方式以游离气为主;高上覆地层压力导致页岩渗透率呈指数下降,页岩气运移能力显著减弱,逸散程度降低,有利于页岩气原位聚集。④温度、压力变化对气体扩散作用影响复杂,高温会增大气体的扩散系数,加剧气体的运移和逸散,而高压可以减缓或抑制气体的流动,有利于页岩气保存。⑤埋深与压力系数呈现一定的正相关性,埋深对向斜型页岩气藏压力系数的影响作用显著,表明深层向斜型页岩气保存条件趋好。埋深较大的残留向斜核部、凹中隆、有反向逆断层遮挡的斜坡区是复杂构造区页岩气勘探的有利目标。
