在含H₂S和CO₂酸性环境中采用高温高压浸泡腐蚀试验对四丙氟橡胶进行老化处理，考察了温度、H₂S和CO₂含量及环境压力对其耐蚀性的影响。结果表明：影响四丙氟橡胶耐蚀性的最主要因素是腐蚀环境的温度，而H₂S，CO₂含量和环境压力变化对材料性能的影响不大；随温度的升高，材料的力学性能下降，拉伸强度保持率大于69%；四丙氟橡胶具有良好的耐H₂S和CO₂腐蚀性能，在150℃，H₂S分压1.0 MPa，CO₂分压1.5 MPa条件下，其耐蚀性与全氟醚橡胶的相当，以该四丙氟橡胶为材料的封隔器胶筒的密封能力能够达到50 MPa。

High temperature and high pressure immersion corrosion test was employed to age tetrafluoroethylene-propylene rubber (TFEP) in acidic environment containing H₂S and CO₂. And the effects of temperature, content of H₂S and CO₂, and environmental pressure on the corrosion resistance of TFEP were investigated. The results show that the most important effect factor was the temperature of corrosive environment, while the content of H₂S, CO₂ and environmental pressure had little effects on the material properties. The mechanical properties decreased with the increase of temperature, and the strength retention rate was greater than 69%. The TFEP had good corrosion resistance to H₂S and CO₂, which was equal to that of perflouroelastomer rubber in the acidic environment of 150℃, 1.0 MPa partial pressure of H₂S, 1.5 MPa partial pressure of CO₂, and the sealing capacity of the packer made of TFEP reached 50 MPa.
