Design and Application of Low-pressure Gas Recovery Process in An Offshore Oilfield
The low-pressure associated gas generated by an offshore oilfield process treatment system is supplied to gas generators and gas boilers respectively,and the remaining associated gas is burned off by a torch,with an average daily combustion capacity of about 16 000 m3.This paper analyzes the characteristics of low-pressure associated gas in an oilfield,and designs a recovery process scheme suitable for low-pressure and unstable flow associated gas in an oilfield based on the existing production process,and reduces the average daily combustion capacity of the torch to 4 000 m3.The amount of natural gas venting is reduced,and the utilization efficiency and level of low-pressure associated gas are improved,so as to achieve energy saving and emission reduction.
