Design Program of Changchun-Jilin Oil Pipeline in Crossing Stone Formation of Songhuajiang River

The hydrological and geological data of Songhuajiang River in Jilin Province are analyzed and the analytical results will be adopted in Changchun-Jilin Oil Pipeline Crossing project. Two programs, the horizontal directional drilling crossing and tunnel crossing, are compared. The candidate is determined as the horizontal directional drilling crossing with casting-pushing to separate stone formation. This article introduced the design and installation requirements in selection of crossing formation and crossing in-out-point, the determination of design parameters, crossing technical measures and stone formation crossing.
