摘　　要：分析了影响吐鲁番油田大斜度井固井质量的因素,提出了改善大斜度井固井质量的几种方法,印调整钻井液性能,提高套管居中度,选择合适的隔离液和冲洗液以及优选水泥浆,并在吐鲁番油田的胜南2-1、胜南2-6、胜南2-5和胜南2-2定向井的固井施工中应用。结果表明,采用以上几项措施效果很好,能提高吐鲁番油田的固井质量。Methods to improve the cementing quality of high -angle wells in Tuha Oilfield are presented in this paper, which includes adjusting drilling fluid performance, setting more centralizers at proper depths, using suitable spacer fluid and flushing fluid, and optimizing cement slurry design. Fields practices following these methods were beneficial.
