吉拉克凝析气田天然气处理装置优化运行方案比选

Jilake device operation optimization scheme selection

目前吉拉克凝析气田开发进入后期,油气产量、压力不断下降,生产井陆续关停,实际产能与原设计相差较大,三叠系和石炭系天然气处理装置均在低负荷运行,设备处理能力闲置率较大,造成装置运行成本较高,经济性较差。为改变这种生产状况,提出将三叠系和石炭系的天然气按压力机制统一考虑,简化工艺流程,适当调整两套装置的操作参数,尽可能利用处理装置的已建设施对原料气进行处理,以满足天然气外输气中烃和水露点的要求。

During the later development period of Jilake condensate gas field,both the production of oil and gas and the pressure decrease constently,production wells were closed or stopped successively.At present,the actual production capacity has larger difference with the original design,both the natural gas treatment devices of Triassic and Carboniferous are both under low load operation,the equipment capacity has not yet been fully used,which cause the devices′operation cost high and economy poor.To change the production situation,the natural gas of Triassic and Carboniferous are considered uniformly by pressure mechanism,the process is simplified and the operation parameters of the two devices are adjusted appropriately.The built facilities were used best to treat raw material gas for meeting the requirements of water and hydrocarbon dew point of the natural gas transportation.
