Our mobile drilling rig manufacturing base is designated by China National Petroleum Corporation (CNPC). We have introduced advanced design and international manufacturing technology developing a series of mobile drilling rigs and workover rigs.
Our series of mobile drilling rigs is reliable in overall performance and easily operated, and can not only be used for drilling, but also for workover. With the features of self-guyline field installation, small footprint and strong mast rigidity is is especially suitable for work on well sites with limited area and artificial islands. It has attained three national patents and has been authenticated by API.
Our truck-mounted drilling rigs have been designed in accordance with API Spec. 4F, 7K and 8C (latest revision) and fulfill the standards GB3826.1, GB3836.2, GB7258, SY6584 as well as the “3C” compulsory standard. We have strengthened safety and inspection measures to meet the requirements of HSE.
We are able to provide well drilling and workover equipment for cluster wells on artificial islands and artificial wellsites for the development of offshore oilfields. Our main products include module drilling rigs, drilling rig tracks, mobile platforms, a drilling fluid circulation system, well workover equipment and auxiliary equipment.
We provide unique well drilling and workover related technology for cluster wells on artificial wellsites that has achieved advanced national levels.
Remark: All mobile drilling rigs / truck-mounted drilling rigs can be highly customized according to customers' demands. Please inquire.
