摘要
深层及超稠油油藏具有埋藏深、原油粘度高、储层物性差及启动压差大等特点,现有的热采技术尚不能实现经济高效的开发。蒸汽辅助重力泄油技术(SAGD)是开采特、超稠油最有效的技术之一,近年来在加拿大已广泛应用于生产实践。根据钻井方式、到达目的层的方法、井的数量、组合方式、井在油田中的位置以及注蒸汽的方法等几个方面,国外将SAGD技术划分成几种类型,在现场实施中取得了很好的效果。
Deep heavy oil reservoirs and extra-heavy oil reservoirs were characterized by deep burial,high viscosity,poor physical property and big starting pressure difference,so it was difficult to realize high efficient development by using current thermal recovery technique.Steam-assisted gravity drainage technique(SAGD) was one of the most effective ways to recover extra-heavy oil,and it was widely used in practice in Canada.SAGD is divided into several types according to drilling mode,ways of reaching target zone,the amount of well,array mode,well position in oilfields and way of steam injection,etc..
