The oilfield has entered a high water cut development period due to long-term water injection development.In order to solve the problems such as uneven operating load of equipments,continuous increase of operating energy consumption,and so on which caused by the increasing water content,various pre-separation technologies based on different principles were summarized,the working principle,advantages and limitations of gravity type,centrifugal type,and demulsification technology were analyzed,The treatment effect of pre-separa-tion technology and its importance for oilfield development were introduced,more than that,the future develop-ment direction of high water content produced liquid tubular pre-separation technology was outlooked.
