摘要: 一个油气藏从油气生成到消亡的进程,与其所经历的地质历史、地质作用和人工开采因素有关。人工开采加快油气藏消亡的进程,开发方式和技术手段不同会影响油田的开发生命周期。通过不断创新应用方法和技术,增加地质储量和可采储量,可有效延长油田的开发生命周期。根据大庆油田萨北开发区不同开发阶段的特点和矛盾,以提高油田采出程度为主线,论述了以早期注水、分层开采、加密调整为主的二次采油技术和以聚合物驱、三元复合驱为主的三次采油技术以及以自适应驱油体系为主的化学驱后四次采油技术对延长萨北开发区开发生命周期的开发实践。未来勘探开发技术水平的不断提高,将增加油田地质储量和可采储量,基于翁氏预测模型和偏正态分布数学模型,预计萨北开发区可以开采至2110年以后。

Abstract: The process from hydrocarbon generation to extinction for an oil-gas reservoir is related with its geological history, geological processes and artificial development. Artificial development will speed up oil and gas depletion; the development life of oilfields is influenced by diverse exploitation methods and technologies, and can be effectively extended by the constant innovation and application of new methods and technologies, and the increase in geological and recoverable reserves. This paper discusses the actual exploitation according to the characteristics and contradictions at different recovery stages in Sabei development zone in Daqing Oilfield, focusing on enhancing the recovery percentage of oil reserves. Specifically, the following oil recovery techniques are applied:secondary recovery dominated by early water-injection, separate zone production and infilling adjustments, tertiary recovery dominated by polymer flooding and alkali/surfactant/polymer (ASP) flooding, and quaternary recovery after chemical flooding dominated by self-adapting recovery system With the increasing improvement in the exploration and development technologies in future, geological and recoverable reserves will be increased. Based on Weng's prediction model and the mathematical model of skewed normal distribution, it is estimated that the development life of the Sabei development zone can be extended beyond 2110.

Key words: Daqing oilfield, oilfield development life, oil and gas accumulation, destruction and extinction, primary recovery, secondary recovery, tertiary recovery, quaternary recovery
