进入21世纪以来,由于经济发展的需要造成了大量的能源消耗;所以,现阶段实现石油天然气等能源的高效开发就变得至关重要。在我国剩余的不可再生能源中,油气资源已经成为了主要的勘察对象,而且在该种油气资源开采的各种手段中,采取合理的驱油技术是保证获得最大经济效益的重要条件。而且经过我国相关技术专家近些年的实践,我国在注气驱油方面已经取得了十分重要的进展。但是,许多油气开发企业都受传统技术手段的束缚,对注气驱油技术的应用起步较晚,进而在采收率方面还有待提高;而且国内现在还存在注CO_2与氮气谁更优的争议。但是从技术手段、原料采取等方面分析,注氮气要比注二氧化碳具有更好的效果。下面,本文就注氮气驱油技术发展现状与启示作具体阐述。 Since entering the 21st century, a large amount of energy consumption has been caused by the needs of economic development. Therefore, it is of crucial importance to realize the efficient development of energy sources such as oil and gas at this stage. Among the remaining non-renewable energies in our country, oil and gas resources have become the main targets of investigation. In all kinds of oil and gas exploitation methods, adopting reasonable oil displacement technology is an important condition for ensuring maximum economic benefits. Moreover, after the practice of China’s related technical experts in recent years, China has made very important progress in gas injection and oil displacement. However, many oil and gas development companies are constrained by the traditional technical means, and the application of gas injection and oil displacement technology has started relatively late, and thus the oil recovery needs to be improved; moreover, there is still controversy in the country which is better for CO2 injection and nitrogen . However, from the technical means, raw materials and other aspects of analysis, nitrogen injection than carbon dioxide injection has a better effect. Below, this article on the development of nitrogen displacement technology and inspiration for specific elaboration.
