摘要

曲靖盆地是区域性走滑构造应力作用下形成的第三纪箕状断陷湖盆残留盆地。研究了构成曲靖盆地生物气系统的气源岩、储集层、盖层等成藏基本要素 (尤其是气源岩埋藏史)和该生物气的运聚特点、含气系统在剖面上的特征以及构造演化对成藏的控制作用等,认为由于受构造抬升影响,造成储层、盖层破坏和含气圈闭规模较小,该盆地生物气藏的资源潜力有限,生物气勘探前景并不十分乐观。

Abstract

Qujing Basin in Yunnan province is a Tertiary fault-subsidence lacustrine rudimental basin, and is formed due to the regional strike-slip tectonic stress.Thetext systematical investigate the combined characteristics of source rocks, reservoirs and cap rocks in the biogas system(especially the burial history analyses of source rocks), migration and accumulation characteristics of biogas, the sections characteristics of hydrocarbon and the controlling effect of tectonic evolution in the process of gas-accumulation in Qujing basin. Through the comprehensive analyses and in-depth research of Hydrocarbon-Geology, it can be concluded that the future exploration of potential biogas-reservoirs in the Qujing basin is not very optimistic for the damage of reservoirs and cap rocks caused by tectonic-uplift and the correspondingly small scale of trap.
