| 中文摘要:分析了丛式井在解决普光气田地质不确定、地表环境复杂等问题方面的技术优势。在对普光气田井身结构必封点分析的基础上，确定了各层套管下深范围，以此为据，优化出适用于普光气田水平井的2套井身结构方案。以普光105丛式井平台为例，分别对普光105-1水平井和普光105-2井的井身结构进行了优化设计，并对其钻井施工效果进行了总结与分析。应用实践证明，丛式井有助于缩短该地区的钻井周期、降低复杂失效、提高钻井速度，具有较为广阔的应用前景。 |

| Abstract:Analysis was made on the technical advantages in solving the difficulties of geological uncertainty and complicated surface environment. Based on the analysis on the setting position of casing program of Puguang gas field, the scope of casing setting depth was determined. Then 2 sets of well structure scheme were proposed for horizontal well in Puguang gas field. Take the Puguang 105 cluster well platform for an example, the well structure of 105-1 and 105-2 were optimized, and the drilling results were summarized and analyzed. The practice shows that cluster well could shorten the cycle of drilling, reduce the failure caused by complicated situation and improve drilling efficiency. |
