Now most oil fields have been high water-cut, so studing fluvial sandbody architecture can provide important academic evidence to realize the distribution of remained oil and hold peak or settled production, fn addition to ,how to combine the facts of macroscopical and microcosmic, and how to combine the result of well network and fields outcrop.then instruct production and practice, which is the stress of this article.

在目前大多数主力油田已进入高含水期的形势下，研究河道砂内部建筑结构，可以为了解剩余油分布规律，保持油田高产稳产，提供重要的理论依据。此外，如何将宏观与微观的因素结合起来，将密井网研究成果及野外露头研究成果有机的结合起来，用于指导油田生产实践，也是本次研究的重点之一。

In the Eogene and Neogene, Qaidam Basin experienced the multiphase tectonic movement; the paleoclimate evolved from warm-humid to arid; the water in the basin was gradually salinized; the depocenter migrated from west to east. The master factors and developmental characters of lithologic hydrocarbon reservoirs have their own particularity. Taking the fine exploration zones of the southwest hydrocarbon-rich depression in Qaidam as the key point, with the analysis of source-rock distribution, sedimentary evolution and sedimentary system distribution, the author proposes that the density difference increases after the fluvial water enters, then clam and bar sand bodies are formed easily due to density flow. Highstand system tract and transgressive system tract below the maximum flooding surface are the main exploration areas of lithologic reservoir.

柴达木盆地古近纪－新近纪经历了多期构造运动，古气候由温湿向干旱演变、湖盆逐渐咸化、沉积中心由西向东迁移的演化过程，地层岩性油气藏的主控因素和发育特征有其特殊规律，以柴达木盆地柴西南富油气凹陷精细勘探区带为重点，通过分析烃源岩展布、沉积演化和主要沉积体系展布，提出咸化湖盆在河流入湖后因密度差较大，易形成密度流等成因的各类滩坝砂体，最大湖泛面之下的高位体系域、湖侵体系域是地层岩性油气藏的主要勘探领域。
