series of workover rigs with maximum static load ranging from 300 to 2250kN ( 67440-505800 lbs ) and installed power ranging from 235 to 1300HP, including XJ150, XJ250, XJ350, XJ450, XJ550, XJ650, XJ1000 and XJ1200. The power system, drawworks system and driving system are all installed on a carrier, therefore it is easy for installation and movement. These rigs are suitable for workover operation for wells ranging from 1000 m to 9000 m , and for drilling operation for medium and shallow wells if equipped with a rotary table.A self-propelled workover rig is mainly composed of chassis, power and driving system, drawworks system, mast, hydraulic/air/electric control system and rotary system. The rig traveling and operation are all powered by a deck engine. Main manufacturing equipment/parts conform to related API specifications. Design features1. Mast and operation parts are all installed on a chassis which will ensure easy installation and fast movement. 2. Well-known engine and hydro mechanical transmission are adopted. 3. Self-propelled chassis will be more suitable for complicated oilfield conditions. 4. The integral Lebus groove in main drum will make lines in good order and avoid inter twist. 5. Power for chassis and deck operation parts are taken from engine respectively through a transfer case.Specifications Operating depth : 1000m to 9000m Hook load: 300kN to 2250kN (30T to 250T)Model XJ250XJ350XJ450XJ550XJ650XJ1000XJ1200Service depth (2-7/8" UE tubing) (m)3200400055007000850080009000Workover depth (2-7/8"DP)(m)2600320045005800700065007500Max Hook load (ton/kN)400100 (900)126(1125)150 (1350)165(1470)190(1700)250 (2250)Max lifting speed of hook (m/s)1.41.321.231.331.311.361.36Overall dimensions in traveling condition(m)13.72×2.7×4.1817.5×2.8×4.217.6×2.9×4.317.6×2.9×4.320.2×3.4×4.421.3×3.3×4.522.5×3.3×4.5
