资料简介

中国石油集团碳捕集利用项目位于鄂尔多斯盆地东部斜坡区三叠系延长组，位于陕西省北部。鄂尔多斯盆地是我国西北地区最重要的能源化工基地，油气资源和煤炭资源十分丰富。延长组拥有一系列低渗、特低渗油藏。这些储层是典型的盆地，储层渗透率小于110-3μm2（1毫达西，mD），占延长探明总储量的60%。致密油气藏蕴藏着巨大的石油储量，是延长组稳产增产的关键。然而，陕西省北部干旱半干旱地区缺乏注水开发的水资源，这就需要增加采油量。提高陕西省北部低渗特低渗透油藏开发利用效率，成为鄂尔多斯盆地油气开发项目的技术难题。

The Yanchang Petroleum Group’s Carbon Capture and Utilisation Project is located in the northern Shaanxi Province, China and focuses on the Triassic Yanchang Formation on the eastern slope of Ordos Basin. Ordos Basin in north western China is the most important energy-chemical base with abundant oil, gas and coal resources. The Yanchang Formation hosts a series of oil fields that are low and ultra-low permeability oil-bearing reservoirs. These reservoirs are typical of the basin, where the reservoir permeability is less than 1 x 10-3 μm2 (1 millidarcy, mD); these accumulations account for 60% of Yanchang total proven reserves. The tight reservoirs contain huge oil reserves and are the key to maintain steady and increasing yields from the Yanchang Formation. However, the arid and semi-arid northern Shaanxi Province, has a lack of water to conduct water flooding development, which is needed to increase oil production. Improving the efficiency of the development of low and ultra-low permeability oil-bearing reservoirs in the northern Shaanxi Province with a lack of water becomes a technical problem for Ordos Basin’s oil and gas development projects.
