喇嘛甸油田萨零组精细地质描述

应用精细地质研究方法,开展了萨零组地质特征研究,首先采用“旋回对比、分级控制”的方法,对萨零组储层进行层组划分,萨零组由原先的3段精细划发为8个小层和1个夹层;其次绘制了萨零组断层平面分布图、构造剖面图、各小层砂体的等厚图和沉积相带图,揭示了萨零组的构造特征、沉积环境特征和储层性质,首次确定了萨零组为三角洲外前缘沉积;还研究了萨零组油界面和油气分布,通过试油（气）资料证实萨零组具有一定的产油、气能力、为萨零组的开发奠定了基础。

Fine Geological Description of Sa-0 Member in Lamadian Oil Field

Studying on characteristics of Sa 0 reservoir by fine geological research method.First,based on the method and principle of "cyclic correlation and graduation control", three original sections of Sa 0 reservoir member are divided into 8 small layers and 1 interlayer. Then,finished fault plane distribution, reservoir, structure profile, sandstone isopach and sedimentary facies maps of Sa 0 member; opened out structure, sedimentary environment and reservoir characteristics of Sa 0 member,Sa 0 member is defined as the external delta front facies for the first time. Finally, studied the interface and distribution of oil and gas of Sa 0 member, it is confirmed that Sa 0 member possesses oil and gas production capacity through testing, the solid foundation is established for development of Sa 0 member.
