Abstract: To meet the demand for offshore deepwater oil and gas exploration, BOMCO has developed the 9000-meter deepwater drilling package on the basis of the existing onshore 9000-meter drilling rig. With adoption of modern design method, the overall weight of drilling package is controlled thanks to the efforts to improve the structures and materials of the main parts, such as conventional deep-well derrick of onshore drilling rig and large-power winch, and optimize the weight of various units. Technological research is focused on the overloaded rolling rig sliding device and overall positive pressure explosion-proof driller room in the light of the requirements for offshore drilling process, filling the domestic technological blanks in design and manufacture of offshore deep-well derrick, overloaded rolling rig sliding device, development of large-diameter diverter and overall positive pressure driller room. The first set of 9000-meter deepwater drilling package was delivered in early 2012 and used to drill dozens of wells abroad. All the facilities of the package have been under normal operation and reliable performance in the past three years. The 9000-meter deepwater drilling package is cost-effective and under mass production, breaking the technological monopoly of foreign offshore deep-well drilling rig.
