以小洼油田洼38块东三段油层蒸汽驱先导试验为例，分析了深层特稠油油藏蒸汽驱采用常规反九点井网开发存在的技术瓶颈，提出高干度注汽、“以采定注”、“回字型”井网设计等改善深层特稠油蒸汽驱开发效果的新思路，对于同类油藏开发有参考价值。
以小窪油田窪38塊東三段油層蒸汽驅先導試驗為例，分析瞭深層特稠油油藏蒸汽驅採用常規反九點井網開髮存在的技術瓶頸，提齣高榦度註汽、“以採定註”、“迴字型”井網設計等改善深層特稠油蒸汽驅開髮效果的新思路，對于同類油藏開髮有參攷價值。

Taking east 3rd member of Wa-38 block as an example of steam flooding test, the bottleneck of steam flooding with in?versed nine-spot well pattern in deep extra heavy oil reservoir were analyzed. Some new ideas such as high dryness fraction, injec?tion optimization according to the production, homocentric squares shaped well pattern and so on were proposed to improve the ef?fects. The results provide reference to the development of similar reservoirs.
