摘要
罗家寨气田是目前全国较大的高含H2S气田且地形复杂,采用丛式井组大斜度定向井、水平井技术培育高产井,是提高气田开发效益的重要途径。文中简述了罗家寨构造地质特点,重点介绍了在罗家寨构造应用丛式大斜度定向井、水平井技术的技术难点和技术措施以及取得的技术指标和勘探成果。介绍了川东地区第一口水平井——罗家11H井和罗家16H-1井的井身轨迹控制情况,为后续在该地区钻水平井积累了宝贵经验。
Loujiazai gas field is a high H2S gas field and its geologic structure is very complex, using high-inclination cluster directional wells and horizontal wells are an important approach to improve gas field development benefit. The paper presented the geologic features of Loujiazai structure, technical difficulty and technical measures of applying high-inclination cluster directional wells and horizontal wells techniques, and achievedwith qualification and outcome. At the same time, the wellbore trajectory control of well Loujia 11H and well Loujia 16H-1 was also introduced. It provides experience for horizontal well drilling in the area in the future.
