石油钻井方面

点击次数:531 发布日期:2022-07-12

石油钻井方面:
  在钻井、定井、固井和压裂操作所需要的各种泥浆中HEC和HPMC作为增稠剂,使泥浆获得良好的流动性和稳定性。在钻井中提高泥浆携带能力,并防止大量水分从泥浆进入油层,稳定了油层的生产能力。

HPMC纤维素掺量与砂浆需水量表现为先减小后明显增大。水剂的掺入改善了砂浆需水量增大的问题,但必须合理控制其掺量,否则有时会使新拌水泥砂浆的水下抗分散性有所降低。掺入HPMC的水泥净浆试件与空白试件结构上差异不大,水中浇筑和空气中浇筑的水泥净浆试件结构和密实度差距不大。水下成型28d的试件略显酥松。主要原因是HPMC的加入,虽然大大降低了水中浇筑时水泥的流失和分散程度,但同时也使水泥石的密实程度有所降低。工程中在保证水下不分散效果的情况下,因尽量减少HPMC的掺量。掺入HPMC水下不分散混凝土外加剂,控制好掺量对强度有利,试点工程表明,水中成型混凝土与空气中成型的强度比为84.8%,效果比较显著。
