Abstract: The falling of crude oil price in the global market brings a heavy blow to the global oil industry and petroleum engineering technology service industry. By analyzing on-shore and off-shore drilling contractors and international oilfield service companies,this paper summarizes existing problems in the operation and development of global oil service industry at present, and the measures relevant companies and oil service industry have taken in the context of low oil prices, and we conclude that China's government and universities should provide greater technical support for the petroleum engineering technology service industry,that enterprises should focus on technology and management innovation,reforming the state-ownership in the industry into mixed ownership, and that the industry must take the opportunity of development in the "Internet+" era so as to meet the requirements of internationalization.

Key words: low oil prices, petroleum engineering technology, oil service industry, oil-gas economy, innovation in enterprise management
