Research and Control Strategy of Condensate Gas Production System in Offshore Gas Field
In the process of offshore condensate gas field production,with the change of condensate gas production conditions,the flash problem of condensate oil occures frequently,resulting in the decrease of condensate oil production and the large increase of the hydrocarbon gas discharge.Taking the treatment process of Liwan gas field as an example,the mechanism of condensate flash is systematically expounded,the enrichment of light components and the pressure difference of saturated steam lead to the intensification of flash,and the overall production strategy of controlling the pressure drop is proposed.The control method around the control node of the condensate treatment unit can effectively reduce the condensate flash vapor volume of more than 14 000 m3/d and produce significant economic and environmental benefits.
