| 中文摘要:莺深2井是大庆油田2008年完钻最深的一口天然气探井。根据松辽地区的特点，在深入分析影响该地区钻井速度和安全钻进的主要因素的基础上，针对不同的影响因素，进行了优化钻井设计研究，主要从优化井身结构、优选钻头和优选钻井工艺方式几个方面对莺深2井进行了设计优化。实钻结果表明，该井创造了大庆油田超过5500 m深层天然气探井钻井记录，并且采用氮气及水包油欠平衡钻井技术取得了勘探突破，中途测试获得低产气流，完钻测试获得工业气流，取得了较好的勘探效果。 |

| Abstract:Well Yingshen 2 is the deepest natural gas exploration well of Daqing oilfield, which was finished drilling in 2008. According to the characteristics of Songliao area and based on the analysis on the main factors which affected drilling speed and safe drilling, research of optimized drilling design was made. Optimization design on well structure, optimal selection of bit and drilling technology were carried out for well Yingshen 2. The record was set for deep natural gas exploration well of Daqing oilfield with over 5500m depth, exploration breakthrough was made with nitrogen and oil-in-water fluid under-balanced drilling technology; low yield gas flow was obtained in the midway test and commercial gas flow was obtained while drilling completion. |
