摘要
通过对陇川微型断陷盆地露头剖面和钻井岩心的岩性相分析，结合地震相、测井相研究，认为陇川微型断陷盆地河流沉积类型主要有砾石质辫状河沉积、低弯度河流沉积和交织河沉积，并讨论了河流的变迁及盆地中油气储层的分布规律。
The author thinks that the river deposits from the Longchuan microfaulted basin can be divided into three main types, that is, braided meandering river deposits, low sinuous river deposits and anastomosing river deposits on the basis of lithofacies analysis and grain size data in the Longchuan microfaulted basin. The change of the river and the distribution of oil/gas reservoirs in the basin is also discussed in this paper.
