Research Progress and Key Research Directions of Wellbore Fluids in China and Abroad
摘要
Abstract
Wellbore working fluids are critical enabling technologies for the safe and efficient exploration and development of unconventional,deep,and ultra-deep oil and gas resources.This paper reviews and benchmarks domestic and international advances in wellbore fluid technologies.The results show that comparable performance has been achieved in high-performance water-based drilling fluids for unconventional reservoirs and in wellbore fluids for deep and ultra-deep applications,while notable gaps remain in reservoir protection technologies and intelligent control systems.With the continuous deepening of exploration and development,existing wellbore working fluids are still insufficient to meet the increasing demands of deeper,longer,and smarter drilling operations.Therefore,further efforts are required to promote iterative upgrading toward environmentally friendly,high-performance,and intelligent wellbore fluid systems,and to develop fully autonomous formulations integrated with advanced testing and control technologies.关键词
