一、稠油热采技术的现状(1)蒸汽吞吐采油技术。蒸汽吞吐是指先向油井注入一定量的蒸汽,关井一段时间,待蒸汽的热能向油层扩散后,再开井生产的一种开采稠油的增产方法。蒸汽吞吐是一种相对简单和成熟的开采稠油技术,国外在20世纪50年代开始应用,目前在美国、委内瑞拉和加拿大等还广泛应用于开采稠油油藏。蒸 First, the status of heavy oil thermal recovery technology (1) steam huff and puff production technology. Steam Hunt refers to the injection of a certain amount of steam to the well first, shut down for a period of time until the steam heat spread to the reservoir, and then open a production of heavy oil production method. Steam huff and puff is a kind of relatively simple and mature mining heavy oil technology. It was applied abroad in the 1950s and is widely used in heavy oil reservoirs in the United States, Venezuela and Canada. steam
