提高稠油采收率技术研究现状及发展趋势

Present state and future trend of enhance heavy oil recovery technique

热采是目前开采稠油的常规方法,但是其采收率较低。为提高稠油采收率,近年来发展了新的稠油开采技术。主要包括:稠油热/化学驱,蒸汽辅助重力泄油技术(SAGD)及配套技术,超稠油HDCS强化采油技术,稠油化学驱等技术。文中详细阐述了这几种采油技术的国内外发展现状及其作用机理和特点。

Thermal recovery is a conventional method for developing heavy oil reservoirs. Because of its low oil recovery,new techniques,including thermal/chemical flooding technique,SAGD technique,HDCS enhanced oil recovery technique and chemical flooding technique were developed to improve heavy oil recovery in recent years.This paper introduces the development status,the mechanisms and the characteristics of these techniques.And the investigation indicates that with the development of science and technology and increasing requirement on environmental protection,these techniques will be the main techniques for heavy oil development.
