| 摘 要： | 本文对喇萨杏主力三角洲的形成条件、沉积过程和模式演变进行了较系统的研究。重点指出形成该三角洲的河流属中等流量和中等含沙量的河流。指出从葡萄花到东部出水口之间存在一个潜在的、由北向东偏转的、受吞吐流场控制的弧形砂岩发育带，该带是寻找岩性油藏的有利场所。

| Abstract: | The paper deals systematically with the formative conditions,sedimenta-ry processes and model evolution of Lasaxin delta in Songliao Basin.Author empha-sized that the river which led to formation of the delta was moderate in water dis-charge and sand discharge,and that there existed an arc Sandstone belt which ex-tended from Putaohua area to eastern exit.The belt was turned from north to east and controlled by swallow-spit current field.The arc sandstone belt is a prospective area of lithologic petroleum reservoir. |
