摘要
乐安油田为复杂疏松砂砾岩薄层特稠油油藏 ,已累积产油 980× 10 4 t,采出程度 18%以上 ,油藏开采过程中形成了一套独具特色的特稠油油藏开发后期系列工艺技术。本文主要阐述了各类配套工艺技术的应用情况 ,并对经济效益进行了简单评价。现场开发实践表明 ,应用综合配套工艺技术是实现乐安油田稠油高效稳产开发行之有效的方法。
Reservoirs in Lean oilfield are complicated, unconsolidated, glutenite, thin extra heavy oil reservoirs. Cumulative oil production is 980×10\+4 t, and the ratio of total oil produced to OOIP is higher than 18 %. During recovery, a series of unique technologies for late period of extra heavy oil reservoir development have been brought out. This paper mainly discussed the application of various matching technologies, and gave a brief economic evaluation. Field development practice showed that application of integrated matching technologies was a feasible way of developing heavy oil effectively and stably in Lean oilfield.
