马王庙油田马89井区开发对策探讨

On Development Measures for Ma 89 Wellblock in Mawangmiao Oilfield

马王庙油田毛场斜坡带作为马王庙主要勘探阵地,按照“满盆含砂、环洼含油、沿脊富集”的成藏思路,先后成功钻探了马84、马斜89等井,发现多个含油断块。其中,马84井区在新沟嘴组下段Ⅲ油组1、2、3小层获得工业油流,进行了注水开发,相邻的马89井区仅一口井试采,尚未有效动用。分析马84井区开发特征和规律,对马89井区开展油藏工程设计,制定相应开发方案,为马89井区下一步有效动用提供技术支撑。

Maochang Slope Area is the main exploration area in Mawangmiao Oilfield. On the basis of accumulation thinking of “sand bearing in the full basin, oil bearing around the hollow and oil gathering along the ridge”, Ma 84 Well, Maxie 89 Well and other wells are drilled successfully one after another and multiple oil-bearing fault blocks are discovered. Industrial oil run is obtained in the 1st, 2nd and 3rd single layers of Oil Group 3 in lower section of Xingouzui Formation in Ma 84 Wellblock and water-flooding development is done in this area. Whereas adjacent Ma 89 Wellblock has not yet employed effectively except only one well being pilot production. On the basis of analysis of Ma 84 Wellblock development features and rules, reservoir engineering design and development program setting are carried out in Ma 89 Wellblock to provide the technical support for its next step effective employ.
