郭滩水源供水工程是石油天然气总公司1991年的重点建设项目,也是河南油田有史以来最大的水源工程,该工程总投资1968.38万元,其功能是:将郭滩河水通过三眼大口井,经取水泵站、二级泵站提升后,通过(?)529×7输水管送到20.3km外的水处理厂,最后由两条(?)325×6输水管线输送到40万吨稠油处理厂.其中,位于郭滩河岸的取水泵站,原设计为圆形、半地下式结构(见图1),其内径为9.0m,外径10,6m,总高度为28.4m,在黄海高程90.5m以下全部为现浇砼,以上为砖结构,其中地面以下16.5m.井筒底板采用双层钢筋砼密封.在黄河高程85.20m处安装有两台20JD、一台16JD型深井泵.该泵站是通过六条(?)377×7虹吸管(每眼大口井有两条),将三眼内径8.0m深6.0m的大口径辐射井中的水进行虹吸收集的.
The Guotan Water Source and Water Supply Project is a key construction project of the Petroleum and Natural Gas Corporation in 1991. It is also the largest water source project in the history of the Henan Oilfield. The project has a total investment of 1968.38 million yuan. Its function is to pass the Guotan River through three big wells. After the pumping station and the secondary pumping station are lifted, they are sent to a water treatment plant 20.3 km away via a (?)529×7 water pipe, and finally delivered to 400,000 tons of heavy oil by two (?)325×6 water transmission lines. Treatment plant. Among them, the pumping station located on the bank of Guotan River was originally designed as a round or semi-underground structure (see Figure 1). Its inner diameter is 9.0m, its outer diameter is 10,6m, and the total height is 28.4m, in the Yellow Sea. All the below 90.5m in height are cast-in-place concrete, and the above is a brick structure with 16.5m below the ground. The bottom plate of the wellbore is sealed with double-layer reinforced concrete. Two 20JD and one 16JD deep well pump are installed at the elevation of the Yellow River at 85.20m. The pumping station collects the water in large-diameter radiation wells with an inner diameter of 8.0m and a depth of 6.0m through six (?)377×7 siphons (two in each big well).
