四川石油管理局中48定向井,在斜井深200O多米,井斜角43°的情况下,将方位角从194°扭至146°,并在斜井深度、水平位移、准确钻达目标、钻井速度和降低成本等方面创造了四川地区的新水平。中48定向井也是我国目前水平位移最大的一口井。
In the directional well of Sichuan Petroleum Administration Bureau, the azimuth angle is twisted from 194 ° to 146 ° when the inclined shaft depth is more than 200 meters and the inclination angle is 43 °. At the inclined shaft depth and horizontal displacement, the target is accurately drilled and well drilling Speed and reduce costs and other aspects of creating a new level in Sichuan. The 48 directional wells are also the most horizontal wells in China.
