| 中文摘要: |
| 进行了油气田领域遇油膨胀橡胶[三元乙丙橡胶（EPDM）]和遇水膨胀橡胶[氢化丁腈橡胶（HNBR）]膨胀性能的研究。结果表明：温度对EPDM遇油膨胀橡胶和HNBR遇水膨胀橡胶的膨胀性能影响很大，温度越高，膨胀橡胶的膨胀尺寸越大；氯化钠溶液的质量分数越大，HNBR遇水膨胀橡胶的膨胀性能越差。EPDM遇油膨胀橡胶可在室温～200 ℃使用，HNBR遇水膨胀橡胶可在70～200 ℃使用，HNBR遇水膨胀橡胶在氯化钠溶液质量分数0.2以上仍可使用。 |
| 英文摘要: |
| In this work，the swelling properties of oil-swellable ethylene propylene diene monomer rubber（EPDM） and water-swellable hydrogenated nitrile butadiene rubber（HNBR） used in oil and gas fields were studied.The results showed that temperature greatly affected the swelling properties of the oil-swellable EPDM and water-swellable HNBR，and when the temperature increased，the swelling ratio increased.It was found that when the mass fraction of sodium chloride solution increased，the swelling performance of the water-swellable HNBR decreased.The oil-swellable EPDM could be used in the temperature range from room temperature to 200 ℃，while the water-swellable HNBR could be used from 70 to 200 ℃.The water-swellable HNBR could be used in the sodium chloride solution having a mass fraction above 0.2. |
