適用環境：丁晴橡膠為常規固井用，井下溫度不高于120攝氏度時使用，聚氨酯則更加耐高溫。丁晴橡膠的柔韌性和耐磨程度均優于聚氨酯，所以目前各大油田均采用性能更好的丁晴橡膠。
Application Environment: Buna-N rubber is used for well cementation when the temperature of down hole is lower than 120 centigrade. Although Polyurethane material has higher-temperature resistant than Buna-N rubber, Buna-N rubber has better flexibility and wear-resistance than Polyurethane. Thus, Buna-N rubber is adopted in big oil fields.

產品特點：孔徑均符合行業標準，不影響泵壓，內部固件為可鉆性很好的鋁合金，同時鋁合金的機械性能完全優于塑料或玻璃鋼，減少了固井作業后鉆除的時間，并提供了膠塞在套管下行過程中足夠的支撐力。
Product features: The bore diameter meets professional standard and has no influence on pump pressure. The drillable aluminum alloy is  adopted in internal firmware which mechanical capacity is much better than plastics or glass fiber reinforced plastics. It reduces drilling time and provides the cement plug enough braced force while cement plug is descending in casing.
