摘要
呼2井是发现呼图壁气田的第一口井,该井井身结构复杂,井内有落鱼。建设呼图壁储气库,有一批类似呼2井的老井需要封堵,能否有效封堵呼2井,是呼图壁油气田改建地下储气库的关键。施工中,根据地质情况,结合工程需要,采用超细水泥浆体系和G级微膨胀水泥浆对产层、隔层和井筒分别进行封堵,取得了成功。该井的封堵成功,对储气库的其他老井封堵具有借鉴意义。
Hu-2 Well, a discovery well of the Hutubi gas field, was of complex wellbore configuration and found that there was fish in the well. The construction of Hutubi gas storage needed the plugging of several old wells similar to Hu-2 Well. So, the effective plugging of Hu- 2 Well was the key of the reconstructing underground gas storage in Hutubi field. According to the geological conditions, combined with the engineering requirements, the successful plugging in this well is all gained by using ultra-fine cement slurry system and G-level micro ex- pansion cement slurry for gas production layer, barrier layer and wellbore, respectively.
