摘　　要：随着石油资源的不断开发,常规石油资源已难以满足需求,人们把目光转向海上稠油。测试是油气勘探开发的关键步骤,通过测试可以得到地层流体的黏度、密度和组分等物性参数,为油田开发提供参考依据。本文对常见的海上人工举升工艺进行了介绍:螺杆泵电缆加热举升、多级气举阀气举、连续油管气举、电潜泵举升和射流泵举升。通过对各种人工举升的优缺点进行分析,针对海上稠油举升的特点,优选出一种组合人工举升工艺。With the continuous development of oil resources,conventional oil resources are no longer sufficient to meet the demand,and people are turning their attention to offshore heavy oil.Testing is a key step in oil and gas exploration and development.Physical parameters such as viscosity,density and components of formation fluids can be obtained through testing,which provides a reference basis for oilfield development.This paper introduces common offshore artificial lifting processes:screw pump cable heating lift,multi stage gas lift valve gas lift,coiled tubing gas lift,electric submersible pump lift and jet pump lift.By analyzing the advantages and disadvantages of various artificial lifting,a combined artificial lifting process is preferred for the characteristics of offshore heavy oil lifting.
