摘要（英）：

The invention relates to a suspension device and suspension method of a water-secluding pipe system deepwater well drilling, wherein the suspension device comprises a fixed tray, hydraulic cylinders, pulleys and a movable tray. The fixed tray is fixedly connected on a well drilling table face, and a through hole allowing for passing of a water-secluding pipe string is formed in the middle of the fixed tray. The number of the hydraulic cylinders are two or above, and the hydraulic cylinders are installed uniformly on the fixed tray along the edge of the trough hole. The top end of a piston rod of each hydraulic cylinder is connected with the corresponding pulley in a rotating mode. A through hole allowing for passing of the water-secluding pipe string is formed in the middle of the movable tray, the outer side of the movable tray is connected with one end of a steel wire rope, and the other end of the steel wire rope bypasses the pulleys and then connected to the fixed tray.
