摘要
根据哈山区块地层特点,优选出胺基强抑制封堵防塌钻井液体系。该钻井液体系抑制性好,封堵性强,具有一定的抗碳酸根污染能力,在哈山1井和哈山2井取得了良好的现场应用效果,施工中井壁稳定,起下钻畅通无阻,电测及下套管均一次成功。
In view of the characteristics of the formation of Hashan Block,a strong amino drilling fluid system having good inhibition,plugging and anti-sloughing properties was selected through optimization. This drilling fluid system had good inhibition property,strong plugging performance as well as the anti-carbonate contamination capacity to some extent,and showed good field application effect when used in No. 1 Well and No. 2 Well of Hashan Block. The shaft wall was stable,both pulling out of hole and running in hole were unobstructed,and successful wireline logging operation and running casing operation were realized in the first time during the construction when this drilling fluid system was used.
