辽河油田是全国大型油田,最高年产油1500多万吨,以生产稠油,高凝油著称,其产量占总产量的三分之二以上。稠油、高凝油开采工艺比较复杂,世界上只有少数几个国家可以开采,利用注汽热采技术就是有效的方案之一。在采油生产过程中有大量高温含油污水的热量被白白放掉,造成很大的浪费,所以回收利用这部分热能,符合节能减排等国家政策方针,同时降低采油生产成本,效益显而易见。本文浅析一下这部分能源的利用与效益。
Liaohe Oilfield is a large-scale oilfield in China with a maximum annual output of more than 15 million tons of oil. It is famous for producing heavy oil and high pour point oil, and its output accounts for more than two thirds of the total output. Heavy oil, high pour point oil extraction process is more complex, only a few countries in the world can be exploited, the use of steam injection heat recovery technology is one of the effective programs. In the process of oil production, a large amount of heat with high temperature oily wastewater is let go, causing a great waste. Therefore, recycling this part of the heat energy is in line with the national policies and guidelines such as energy conservation and emission reduction. At the same time, the cost of oil production is reduced, and the benefits are obvious. This article analyzes the utilization and benefits of this part of the energy.
