摘要
海上石油安全生产规定海上生产井必须下入井下安全控制管柱，然而现有井下安全控制管柱的耐温性能达不到注热井的要求。为此，在分析海上注热井对井下安全控制管柱要求的基础上，通过优选密封材料和密封方式，研制了由Y241型热采封隔器、耐高温井下安全阀、隔热型补偿器和井口穿越装置等关键工具组成的耐高温井下安全控制管柱。室内试验及现场试验均表明：Y241型热采封隔器、耐高温井下安全阀、隔热型补偿器和井口穿越装置在常温和350℃高温下的密封性能良好；Y241型热采封隔器的单流阀和耐高温井下安全阀开启、关闭操作灵活。这表明，耐高温井下安全控制管柱系统的结构设计合理，耐温性能、密封性能等能满足注热井的要求，可以提高注热井的安全性。
Abstract
According to safety regulations for offshore oil production,all offshore producers are required to be equipped with subsurface safety control devices.But all available subsurface safety control devices currently available may not meet the heat-resistant demands for wells with thermal production.Considering the demands of offshore heat-injection wells for subsurface safety control devices,Y241 type thermal packer,heat-resistant subsurface safety valve,insulated compensator,wellhead crossovers and other heat-resitant subsurface safety control devices were developed through a combination of optimal sealing materials and sealing modes.Laboratory and field tests showed that Y241 type thermal packer,heat-resistant subsurface safety valve,insulated compensator and wellhead crossovers presented outstanding sealing performances under room temperature and excellent performance with high temperatures up to 350℃.The results demonstrate that the newly-developed heat-resistant subsurface safety control devices possess rational structural design,desirable heat-resisant and sealing performances to satisfy the demands of heat-injection wells.the application of these devices can effectviely enhance safety performances of heat-injection wells.
