Innovation Practice and Prospect of Oil Production Technology in Offshore Oilfield

Oil production technology is the core technology of oil and gas development., is the key point to ensure the recovery of oil and gas wells and improve the quality and efficiency of oil field production, and plays a decisive role in improving the efficiency of oil field development. The production wells in offshore oil fields are mainly developed by extended reach wells and horizontal wells, which have the technical development characteristics of "few wells, high production rate and high oil recovery rate", and a high-quality, high-speed and efficient offshore oil field production technology system has been built. This paper summarizes the development history of oil production technology in offshore oil fields, systematically introduced the electric pump lifting technology for large liquid oil wells, the lifting technology for low liquid oil wells, the lifting technology for high gas bearing oil wells, the lifting technology system under special working conditions, and the same well injection and production technology, and puts forward that the iterative upgrading of oil production technology is facing severe challenges such as increasing technical difficulties, improving the level of intelligence, and continuing to reduce costs. In combination with the technical requirements and challenges of offshore oilfield oil production technology, five technical development directions of "integration, differentiation, intelligence, low-carbon and scientific" are proposed to provide reference and reference for the expanded application and technical innovation of offshore oilfield oil production technology.
