渤海辽东湾锦州9-3优快钻井项目共钻井47口,总进尺107 126m;经过394.53d的艰苦努力,创造了平均井深2328.83m,平均井斜角38.47°,平均水平位移1009.8m,平均建井周期7.79d的好成绩。该项目是目前渤海公司优快钻井项目中钻井进尺最多、井数最多、作业时间最长、地质和海况条件最恶劣的项目。该项目应用了渤海优快钻井等10大配套技术,并具有4大特点:首次使用钻井沉箱加钻机滑移底座方式钻丛式生产井;首次在30口井之多的平台上钻密集丛式井;首次采用低温速凝固井水泥浆封固表层技术;首次将优快钻井项目进行跨年度多钻机的连续作业。与1995年8D井相比,锦州9-3油田钻井项目实现了平均机械钻速提高3.6倍,钻井效率提高3.32倍的钻绩,为渤海进一步提高优快钻井水平和推广优快钻井技术,提供了宝贵经验。
A total of 47 drilling wells with a total footage of 107.126m were drilled in the Jinzhou 9-3 Express Drilling Project in Liaodong Bay of Bohai Bay. After 394.53 days of hard work, the average well depth was 2328.83m with an average well inclination of 38.47 ° and an average horizontal displacement of 1009.8m. Well cycle 7.79d good results. This project is currently the project of drilling the fastest drilling in Bohai Company with the largest drilling footage, the largest number of wells, the longest working time and the worst geological and sea conditions. This project has applied 10 large-scale supporting technologies such as the excellent fast drilling in the Bohai Sea and has 4 major features: drilling drilling caisson and drilling production base for the first time using drilling caisson plus drilling base drilling system; for the first time, drilling dense clusters on a platform with as many as 30 wells Wells; the first low-velocity solidification wells with cement slurry sealing surface technology; for the first time will be an excellent drilling project multi-annual multi-drilling continuous operation. Compared with Well 8D in 1995, the Drilling Project of Jinzhou 9-3 Oilfield has achieved an average drilling penetration increase of 3.6 times and a drilling efficiency of 3.32 times. It provides Bohai to further improve the excellent drilling and promote the fast drilling technology. A valuable experience.
