The successful development of the 9000-meter drilling rig has broken the monopoly of foreign companies on ultra-deep oil rigs, and will raise the exploration and development of China's deep-sea oil and gas fields, large-displacement wells and other complex oil and gas fields to a new level, marking China's A major breakthrough in the development and production of ultra-deep oil has represented the highest level of R&D in China,†said Luo Chao, deputy chief engineer of China National Petroleum Corporation Materials and Equipment (Group) Corporation.
At present, there are only a few countries in the world that can manufacture 9000 meters of ultra-deep well drilling rigs, such as the United States and Norway. Therefore, the successful development of the 9000-meter rig is equivalent to climbing the world peak in the field of rig manufacturing. The 9000-meter drilling rig developed by Baoji Petroleum Machinery Co., Ltd. has reached the international advanced level in its lifting capacity, automatic drilling control precision, integrated control level, derrick base structure scheme and design.
With the growing demand for oil in modern society, oil exploration and development is becoming more and more difficult. Nowadays, the exploitation of global oil and gas begins to show a trend towards deep land, harsh areas and oceans. According to the data, among the petroleum recoverable resources in China, about 8.5 billion tons are to be discovered and proven, accounting for 57% of the recoverable petroleum resources. This part of the petroleum resources to be proved is mainly distributed in the four basins of Tarim, Junggar, Qaidam and Tuha in China, which is the main replacement area for China's oil production. At the same time, 73% of this part of the resources is buried below 5,000 meters deep.
Compared with developed countries, China's 9000-meter ultra-deep drilling rig has two innovations. The first is to control technological innovation. The transmission control system of the drilling rig directly adopts the world's most advanced AC frequency conversion control technology to realize the full digital control of the drilling machine operation process, which not only has good safety performance, but also simplifies the transmission system. The second is the innovation of the overall design. The core components of the 9000-meter ultra-deep drilling rig have five technical patents with independent intellectual property rights and global procurement in the auxiliary components.
The development and production unit of 9000 meters drilling rig Baoji Petroleum Machinery Co., Ltd. is China's largest oil drilling equipment R & D and manufacturing base, and has successfully developed a full range of new oil drilling rigs from 1000 meters to 7000 meters. It is reported that the company is developing a 12,000-meter ultra-deep drilling rig, and the preliminary research and development work has been basically completed.
China successfully developed 9000 meters ultra-deep well drilling rig
The reporter learned from China National Petroleum Corporation on the 17th that the 9000-meter ultra-deep well drilling rig developed and produced by China itself with independent intellectual property rights has successfully passed the expert review and acceptance, and has arrived at the Karamay oilfield in Xinjiang. It is expected to start exploration work in June this year.
