| 摘 要： | 在地层承压能力较低的地区进行套管固井作业，由于水泥浆密度较大，极易发生井内漏失，影响封固质量、影响钻井设计目的与要求，因此做好固井前地层承压堵漏是一个很重要的工作环节。通过对漏层进行分析，采用合理的堵漏方法进行承压堵漏，确保了固井的顺利作业。

| Abstract: | Because of high density of cementing slurry, borehole leakage often occurs while casing cementing operated in the area with low formation bearing pressure. Pressure sealing before well cementing is important to guarantee cementing quality and drilling design. Cementing of Well Lishen 1 was successfully operated by the analysis on the leakage zone and rational leakage stopping. |

| Keywords: | Well Lishen 1 pressure-bearing test leakage stopping well cementing |
