延安气田二叠系主力含气层段储层特征及主控因素研究

Reservoir characteristics and main controlling factors in the main gas-bearing intervals of the Permian in Yan’an Gas Field

鄂尔多斯盆地是我国的第二大沉积盆地,富含石油、天然气、煤炭资源,是我国极其重要的能源资源基地。随着国家碳达峰、碳中和的提出,以及国民经济的快速发展,对清洁能源的需求越来越高。天然气作为一种清洁能源,其战略地位更加突出。对鄂尔多斯盆地富含天然气的二叠系山西组、石盒子组储层特征及主控因素开展研究,主要从储层岩石学特征、成岩作用、沉积特征、物性等方面开展了相关研究。对天然气的开发具有重要指导意义。

The Ordos Basin is the second largest sedimentary basin in my country. It is rich in oil, natural gas and coal resources. It is an extremely important energy resource base in my country. With the proposal of national carbon peaking and carbon neutrality, as well as the rapid development of the national economy, the demand for clean energy is getting higher and higher. As a clean energy, natural gas has a more prominent strategic position. This paper studies the reservoir characteristics and main controlling factors of the natural gas-rich Permian Shanxi Formation and Shihezi Formation in the Ordos Basin, mainly from the aspects of reservoir petrology, diagenesis, sedimentary characteristics, and physical properties. It has important guiding significance for the development of natural gas.
