对于开发过程处于中后期阶段的油田,为维持原油产量,各油田均已大面积采取增加注水、注蒸汽的措施提高油井产量,致使油井采出原油含水率迅速上升;同时,近年来随着采油技术的快速发展,各种采油助剂的大量应用也使得原油,特别是稠油的采出液组份变的更加复杂,稠油的高效快速破乳已经成为影响采油成本、原油质量、产量和控制油田环境污染的关键技术。 For the oilfields in the middle and later development stages of the development process, in order to maintain the crude oil output, each oilfield has taken large areas to increase water injection and steam injection measures to increase the production of oil wells, resulting in a rapid increase in the moisture content of crude oil taken from the oil wells. In the meantime, The rapid development of technology and the extensive application of various oil recovery aids make the production of crude oil, especially heavy oil, more complicated. The rapid and efficient demulsification of heavy oil has become a major challenge affecting oil recovery costs, crude oil quality, Key Technology for Controlling Oilfield Environmental Pollution.
