Development Path of Offshore Drilling Equipment in China

Liu Jian

Strategic Study of CAE 2020, Volume 22, Issue 6, Pages 40-48 doi: 10.15302/J-SSCAE-2020.06.006

Abstract:

China has made achievements in offshore drilling equipment, and it can now develop the shallow-water drilling rigs independently. However, as far as deep-water drilling equipment is concerned, there still exists a big gap between China and the international advanced level, which inevitably hinders the deep-water oilfield development in the country. To accelerate the development of China’s offshore drilling equipment, this study first analyzes the development status of the equipment in China and abroad from three aspects: shallow-water drilling machine, deep-water drilling machine, and new-type marine drilling machine; it then summarizes the development status in China and the gap between China and the international advanced level. Subsequently, it studies the key technologies for realizing the localization of the deep-water drilling equipment, and proposes corresponding countermeasures and suggestions. We propose that China should focus its efforts on making breakthroughs in the design, materials, technology, inspection, and sea test of the deep-water drilling rigs. To clarify the development path of the offshore drilling equipment, China should establish and improve the standards and specifications regarding offshore drilling rigs; develop different types of deep-water drilling equipment at different stages and by different levels; establish an integrated testing platform and a sea test base; strengthen inter-industry cooperation; develop this sector in an innovation-driven mode; and promote diversified, serial, automated, and intelligent development.

Technical advance and developmentof China geophysical equipment

Wang Tiejun,Hao Huimin,Li Guoqi,Luo Fulong,Tao Zhifei,Chen Lianqing,Hou Jinhai

Strategic Study of CAE 2010, Volume 12, Issue 5, Pages 78-83

Abstract:

The rapid growth of China petroleum industry has brought about the steady development of its geophysical equipment technology. For example, our seismic instrument has experienced its sixth upgrade. As a result, our geophysical equipment technology has met world advanced standards. After 20 years of painstaking efforts in R&D and by means of technology-introducing, digesting, absorbing, and innovating, some of our vibrator technologies have reached the world advanced level and still some have taken the world leading positions. Our seismic auxiliary equipment has much improved and earned its reputation in the global market after 30 years of independent R&D.
