摘要
针对克拉玛依陆9井区吐谷鲁群高渗砂岩油气藏的储层特点,在优选出钻井液基本配方的基础上,采用了将3种类型暂堵剂复配的屏蔽暂堵技术.室内暂堵评价实验结果表明,采用这种暂堵技术可使岩心的渗透率恢复值明显提高,从而较好地解决了该地区高渗砂岩油气藏的储层保护问题.
For the high_permeability sandstone reservoir in Lu_9 area, Karamay oilfield, a temporary plugging technique is developed by mixing 3 types of bridging agents on the basis of optimizing drilling fluid formulation. Laboratory evaluation experiments show that this technique can drastically increase regained permeability of drilled formation and therefore more effectively protect high_permeability reservoirs.
