摘要
针对高压及含硫化氢(H2S)、氯离子(Cl-)等强酸性环境对井口装置性能的要求,研制了105MPa抗硫井口装置。该井口装置采用十字双翼型结构,同时对金属密封、芯轴式悬挂器、顶丝总成等进行了创新设计。现场应用表明:该井口装置性能完全满足酸性环境下的工作要求,安装操作方便,密封效果好,工作可靠。
In the light of the requirements of wellhead equipment using in the severe sour environ- ment of the oil gas wells which contains high-pressure, hydrogen sulfide and chloride ions, 105 MPa sulfide-resistant wellhead equipment was developed. This equipment was designed for cross structure and the metal seals, mandrel casing hanger and lockdown screw were newly designed. It＇ s the virtue of installation easily and sealing reliably. This equipment was proven suiting to the sour environment and satisfied the design requirements in the field.
