摘　　要：针对某海上高压气田井口压力高、井口温度低、油品凝点高、节流后易出现水合物和出油管线容易冻堵的问题,结合不同生产井节流后的压力,设置不同压力体系井口加热器以满足流体输送要求。文章研究了两种不同高压气田无人平台工艺流程方案:加热器部分降压设计方案和全部降压设计方案,比较了两种方案的技术特点及经济性,最终推荐高压气田无人井口平台采用加热器部分降压设计的工艺流程方案。In order to solve the problems of high wellhead pressure,low wellhead tempera-ture,high oil solidification point and easy to appear hydrate after throttling in an offshore high pres-sure gas field,wellhead heaters with different pressure systems were set according to the pressure system and temperature after throttling in different production.Wells to meet the requirements of fluid transportation.Two different technology flow schemes of unmanned wellhead platform in high pressure gas field are studied respectively:heater section depressurization and whole process de-pressurization.The technical characteristics and economy of the two schemes were compared,and finally the process flow scheme of heater section depressurization design is recommended for the un-manned wellhead platform in high pressure gas field.
