随着定向井、水平井钻井技术的发展,出现了大位移井钻井技术。但关于什么是大位移井?目前尚无统一的定义。初期,认为水平位移超过3 000m就是大位移井。我国前几年水平位移超过 1000m的井,就认为是大位移井。
With the development of directional well and horizontal well drilling technology, a large displacement well drilling technology has appeared. But what is a big displacement well? There is no uniform definition. Initially, that the horizontal displacement of more than 3 000 m is a large displacement wells. A few years ago our country horizontal displacement of more than 1000m wells, it is considered a large displacement well.
