伴随着科技的不断进步,工业化的不断发展,经济建设的石油资源的依赖性越来越强。稠油的开发越来越受到重视,但是稠油的开采过程面临着诸多问题,热力开采是存在着热损失大,产量递减幅度大,损失大,多周期后能量不足,采收效率低下,极易出现汽窜现象。通过不断地进行研究和实验,热力采油技术得到了快速的发展。比如在注蒸汽过程中,在蒸汽中混入其他非凝析气体或者加入一些像发泡剂、降粘剂等化学药剂,提高开采效率,开发蒸汽和气体复合开采的新技术。
With the constant progress of science and technology and the continuous development of industrialization, the dependence on petroleum resources for economic construction has become increasingly stronger. The development of heavy oil is getting more and more attention, but the heavy oil mining process is faced with many problems, such as heat recovery is the existence of a large heat loss, large decline in output, loss, lack of energy after multi-cycle, harvesting efficiency is low, Easy to steam channeling phenomenon. Through continuous research and experiments, thermal oil recovery technology has been rapid development. For example, in the process of steam injection, other non-condensable gases are mixed into the steam or some chemical agents such as foaming agent and viscosity reducer are added to improve the mining efficiency and develop new technologies for steam and gas compound mining.
