LW3-1-1井是珠江口盆地东部地区的第一口深水探井,也是中国海上第一口水深超千米的探井。讨论了LW3-1-1井固井段温度的测定以及低温低密水泥浆体系表层固井,就固井过程中所遇到的问题进行分析并提出建议,为后续深水井开发固井提供了参考。
The LW3-1-1 well is the first deepwater exploration well in the eastern Pearl River Mouth Basin and the first deepwater exploratory well in China with a depth of over one thousand meters. The measurement of the temperature in the cementing section of LW3-1-1 well and the cementing in the surface layer of the low-temperature and low-density cement slurry system are discussed. The problems encountered during the cementing process are analyzed and suggestions are made. reference.
