摘要
火烧油层(火驱)作为提高稠油采收率的重要方法之一,利用油层自身的重质组分燃烧作为动力驱替原油,驱油效率高是其它采油技术所无法比拟的,但是其配套技术难度大、涉及面广,又是制约其效果的关键,对火烧油层效果的影响较大,尤其是深层巨厚稠油油藏其技术配套更为重要。以高升油田高3618块火烧油层试验为例,试验井组火驱后,随着火驱时间的延长,油井产气量大幅度增加,引发出一系列新问题为背景,针对火驱举升工艺上难点和出现的主要问题进行研究与分析,通过开展了相关配套技术研究与试验应用,进而提出了一套适合深层稠油火驱举升工艺的方式与方法,为下一步深层稠油火驱举升工艺技术配套提供依据。
combustion in situ ( fire flooding) is one of important methods to improve heavy oil recovery ratio,utilizing the reservoir it-self heavy component burning as dynamic displacement of crude oil,flooding efficiency is high enough beyond other recovery techniques,but its technology is too difficult and broad,and is the key in restric-ting the effect of combustion in-situ,especially for deep thick heavy oil reservoir,the technical support is even more important. Taking G3618 belt fireflood test as example,after test well combustion drive,the gas production rate increases with the increase of fire flooding time. According to the difficult points of fire flooding tech-nology ,the relevant technologies were researched and applied,some methods suitable for deep heavy oil fire flooding lift technology have been put forward. It provided the basis for applying deep heavy oil fire flooding lifting technology in the future.
