Progress and future development direction of oil and gas development technologies for western South China Sea oilfields

Western South China Sea oilfields have become an important energy production base in South China.However,during the process of achieving stable and increased production,these oilfields face the problems such as increasing production and tapping potential of old oil and gas fields,having great difficulties in developing offshore new field(HTHP and deep-water)gas reservoirs and in producing low-grade offshore reserves,etc.After continuous exploration and practice,a series of key technologies for increasing oil and gas production in the western South China Sea have been formed,which include increasing production and tapping potential of old oil and gas fields,efficient development of new fields and effective production of low-grade reserves.These technologies have promoted the stable and increased production of oil and gas fields in the western South China Sea.The paper further analyzes the challenges still faced by the Western South China Sea oilfields in enhancing the recovery of old oil and gas fields and effective development of ultra-high temperature,high pressure and low permeability gas reservoirs,puts forward the corresponding technology development direction,and strengthens relevant technology reserves.This will lay a solid technical foundation for the efficient development and enhanced oil recovery of oil and gas fields in the western South China Sea,and provide reference for the stable and increased production of oil and gas fields in other regions.
