沉积演化和砂岩分布规律研究是油藏描述的重要内容,无论是在勘探阶段还是在开发阶段都极为重要,不过传统的分析方法多为定性分析,其分析结果极容易受人为因素影响,近年来随着勘探技术和计算机技术的发展,沉积演化和砂岩分布规律向定量分析方向发展。本文以鄂尔多斯盆地延长组油层为研究对象,就延长组沉积演化和砂岩分布规律进行了浅要的研究。
The study of sedimentary evolution and sandstone distribution is an important part of reservoir description. It is very important both in exploration and development stages. However, most of the traditional analysis methods are qualitative analysis, and their analysis results are extremely vulnerable to human factors. In recent years With the development of exploration technology and computer technology, sedimentary evolution and distribution of sandstones develop in the direction of quantitative analysis. In this paper, the Yanchang Formation reservoir in the Ordos Basin is taken as the research object, and the shallow study on the sedimentary evolution and sandstone distribution of the Yanchang Formation is carried out.
