含油污泥调剖数值模拟研究

Numerical modeling study of profile controlling using oil sludge

针对多轮次蒸汽吞吐井存在严重汽窜及含油污泥排放难的问题,提出了利用含油污泥进行高渗透层的封堵。利用CMG数值模拟软件的STARS模块对蒸汽吞吐井含油污泥调剖的影响因素及封堵效果进行了预测,结果表明:不同非均质性的储层对应一个最优的封堵半径和堵剂注入量,模拟结果对指导现场施工有参考和应用价值。

For the serious steam crossflow in multi-steam huff and puff well and the discharge of oil sludge, it is developed of blocking off high permeability zone. The affecting factors and blocking off effects are studied and predicted using STARS module of CMG. The results show： there is a optimal blocking radius and injection on rate of the reservoir with different aeolotropy. The imitation results is very valuable for directing the field conduct.
