Advances in Deepwater Drilling and Completion Fluid Technology at Domestic and Abroad
摘要
Abstract
Global deepwater and ultra-deepwater oil and gas resources account for 44%of total reserves,making their development a crucial pillar of energy supply.In recent years,70%of major new oil and gas discoveries worldwide have originated from deepwater areas.The South China Sea holds abundant deepwater oil and gas resources,and their development is essential for enhancing China's energy self-sufficiency and ensuring national energy security.However,challenges such as high temperature and high pressure,complex geology,hydrate formation,and wellbore stability impose higher demands on deepwater drilling fluid technology.International oil service companies such as Schlumberger,Halliburton,and BP have made breakthroughs in deepwater water-based,synthetic-based,and high-density drilling fluids,which have been widely applied in deepwater blocks such as the Gulf of Mexico and Brazil's pre-salt oil fields.Domestically,China Oilfield Services Limited(COSL)has promoted independent innovation based on multiple oilfields in the South China Sea,developing key technologies such as deepwater hydrate prevention,high-performance water-based drilling fluids,and flat rheology synthetic-based drilling fluids,significantly improving the safety and efficiency of deepwater drilling.This paper reviews recent advancements in deepwater and ultra-deepwater drilling and completion fluid technologies,with a focus on the latest developments in water-based,synthetic-based,and high-density drilling fluid systems,as well as their applications in deepwater oil and gas development,providing a reference for future deepwater drilling and completion fluid technology development.关键词
