摘　　要：针对渤海L油田已进入“双含水,高采出程度”阶段,生产形势逐渐变差,开展了改善油田开发效果的相关研究。采液能力是影响其关键因素之一,通过与陆上油田对标,分析采液能力的影响因素。研究表明海上油田采液速度有“初期高,中期缓,后期缓”的特点,需提高采液速度释放单井产能;油田后期在保证地层压力充足的条件下,可适当增大压差,提高采液速度。As Bohai L Oilfield has entered the stage of“double water cut,high recovery”,the production situation is getting worse,it is urgent to carry out relevant research to improve the development effect of the oilfield.The liquid production capacity is one of the key influencing factors.This paper analyzes the influence of liquid production capacity through bench-marking with onshore oilfield.The research shows that liquid production rate of offshore oilfield is characterized by“high in the initial stage,slow in the middle and later stage”.It is necessary to increase the liquid production rate to release the productivity of single well,in the later stage of oilfield and under the condition of sufficient formation pressure,the pressure difference can be appropriately increased to improve the liquid production rate.
