采用定向钻进行管道穿越是一项新技术,它具有保证管道埋深、质量可靠,工期短,对航运无影响,省工、省投资等优点。管道局在赴美考察和技术谈判的基础上,从美国里丁·贝茨公司引进了目前世界上能力最大的 R B—5型定向钻机,成功地穿越黄河为中原油田至开封的输气管道敷设了穿越复线。穿越总长度1302m,最大偏差为1.5m。φ406mm 的输气管道被埋设在黄河河床下22m 处。
Pipeline through directional drilling is a new technology, it has to ensure that the pipeline depth, reliable quality, short duration, no impact on shipping, labor-saving, provincial investment and so on. On the basis of the visit to the United States and the negotiation of technology, the Pipeline Bureau imported the most capable RB-5 directional drilling rig from the US company, Reading Bates, to successfully cross the Yellow River to lay the gas pipeline for the Central Plains to Kaifeng Through the double line. Crossing the total length of 1302m, the maximum deviation of 1.5m. The φ406mm gas pipeline is buried at 22m below the Yellow River bed.
