Jereh truck/trailer mounted drilling rig is mechanically and hydraulically driven. The power system, drawworks, mast, travelling system and transmission mechanism of the drilling rig are mounted on the self-propelled chassis, which improves the moving efficiency greatly. Now, Jereh truck mounted drilling rig series cover the drilling depth from 1000m to 4000m and maximum static load from 900kN to 2250kN, featuring high operation load, reliable performance, excellent off-road performance, convenient movement and low operation/moving cost, and suitable for drilling operations in shallow and middle deep wells. Besides, drilling rigs for arctic, desert and highland applications are available.
Conform to API Q1, 4F, 7K and 8C Specification and API monogrammed.
The technical parameters and overall design conform to GB/T 23505 Petroleum Drilling and Workover Rigs, suitable for middle & shallow well drilling and workover operations.
Conduct strength analysis for the mast and substructure based on SAFI software.
Modular design achieves fast move and transportation.
Adopt mechanical transmission to enable simple operation and easy maintenance.
Special off-road chassis extends service life.
