针对大庆徐深气田排水采气工艺的不适应性,探索了涡流排水采气工艺技术,施工后试验井排水效果明显,日产气量提高3×104m3/d,现场试验效果良好,为深层气井提供了新的排水工艺。
According to the incompatibility of drainage gas recovery technology in Xushen Gas Field of Daqing, the technology of vortex drainage and gas recovery was explored. After construction, the drainage effect of test well was obvious. The daily gas production increased by 3 × 104m3 / d. The field test was effective and provided a New drainage process.
