| 摘 要： | 马海地区位于柴达木盆地的西北缘，为柴达木盆地“高山深盆地”总背景下的一个次级盆地。其沉积特征一致受构造的控制，主要发育有粒径较大的砾岩、砂岩、粉砂岩，受构造的控制，不同时期沉积特征存在差异，主要发育冲积扇、辫状河、以及滨湖沉积等沉积相，砂岩含量较高，储层较发育。

| Abstract: | Mahai region located at northwest of the Qaidam basin, is a sub-basin of the Qaidam basin as a high mountain deep basin. Sedimentary character in this region was controlled by tectonic which was characterized by development of conglomerate, sandstone and siltstone of alluvial fan, braided river and coastal lake facies with developmental reservoir. |
