摘要

文中论述了礼乐盆地中、新生代地层的发育特征,认为盆地内广泛发育有厚度较大的三叠纪—白垩纪地层,具有中等—好的生气潜力,是盆地内一套具有良好油气远景的主力烃源岩。盆地内新生代地层发育齐全,最大沉积厚度可达6000m,古新统—中始新统为盆地烃源岩发育最有利的层位。

Abstract

Development of Meso-Cenozoic stratigraphic sequence in Lile Basin was studied.It was considered that relative thick Triassic-Cretaceous was widely developed in the basin and showed medium to good potential of hydrocarbon generation, which was one of the main source rocks in the basin.The Cenozoic is completely developed with biggest thickness of 6 000m in the basin.The favourable source rocks for gas were developed in Paleocene to Middle Eocene.
