| 中文摘要:对米桑油田部分井出现的高压盐膏层井段固井质量差且影响下步作业的情况进行了分析，优化了前置液设计、水泥浆设计、入井套（尾）管现场检查、下套管前井眼要求、固井前井筒要求、套管居中、固井注替、固井质量检验等，并成功应用于47井高压盐膏层井段固井，为后续开发井类似井段的固井质量提升提供了借鉴。 |

| Abstract:The poor cementing quality occurred in some high pressure salt-gypsum layer of Missan oilfield is analyzed together with the influence on the next operation are analyzed, the design of preflush and cement slurry, on-site inspection of casing and liner, borehole requirements before casing running, borehole requirements before cementing, casing eccentricity, cementing by mud grouting & displacing and cementing quality checking are successfully applied in the high pressure salt-gypsum sections of 47 well, which provides a reference for the cementing quality improvement in similar situation. |
