摘要
"十一五"以来,胜利油田将数值模拟技术贯穿于稠油热采开发的整个过程,在常规应用方面取得了巨大进展,新建产能超过800×104t。回顾了"十一五"以来胜利油田稠油热采数值模拟方面的研究成果,对近年来稠油油藏开发的热点技术,如火烧油层、泡沫蒸汽驱、HDCS强化热采、热采多分支井等的驱油机理进行了总结概括;在此基础上,重点分析了这几种稠油热采开发方式数值模拟的技术关键,详细说明了模拟过程中其具体的处理办法及现场应用效果。根据研究现状指出了稠油热采数值模拟软件的发展方向,当前最主要是解决稠油油藏敏感性、热化学驱及稠油的非达西渗流3方面的数值模拟问题。
The numerical simulation technology is thoroughly applied for the development of heavy oil during the whole 11th five-year plan,and great progress is obtained in the conventional application with the built productivity exceeding 800×104t.This article reviews briefly the research result of numerical simulation technology used in heavy oil thermal development in Shengli oilfield during the 11th five-year plan,and summarizes the displacing oil mechanism of the hotspot techniques for the heavy oil reservoir development in recent years,such as in situ combustion,steam-foam flooding,HDCS enhanced thermal recovery,multi-lateral horizontal well of thermal recovery,and so on.Based on these,the key techniques of numerical simulation for the heavy oil thermal recovery are analyzed and discussed in detail,including the treatment approach during the numerical simulation and the actual performance of field application in the Shengli oilfield.Also,based on the current situation of research,it is also pointed out herein that,the fur-ther development directions of numerical simulation software for heavy oil thermal recovery are mainly for the resolving of three prob-lems,sensitivity and thermal chemical flooding,and non-Darcy seepage flow of heavy oil.
