摘要
随着曙光油田稠油油藏开发时间延长,受油层发育非均质性的影响,油层纵向动用不均衡,开发过程中存在着诸多矛盾,严重制约了油井的产能发挥。稠油复合选配注工艺正是为了解决这些矛盾而提出的,该技术将稠油选配注技术和化学处理技术有机结合,综合应用到不同开发矛盾的油井上,精细油层处理,使措施更具有针对性,有效提高了油井生产时率和吞吐效果,达到经济高效开发稠油油藏的目的。
With the time extension of heavy oil reservoir development, many problems have been occurred, such as the effect of oil layers heterogeneity and imbalance of producing degree in vertical direction, which has become an important obstacle for oil well production. The injection-allocation technology is therefore put forward to solve these problems. Combined the heavy oil injection-allocation technology and chemical processing technology together, the new technology is comprehensively applied to oil wells and effectively improve the oil well production rate and the stimulation effect, and achieves economic efficient development of heavy oil reservoirs in purpose.
