氟弹性体在石油和天然气工业中的应用一直在不断增长之中。由于传统氟弹性体性能的限制,在今天高温高压(HPHT)和苛刻化学介质的环境中,为了满足特定的应用而选择一种适宜的弹性体材料已经愈发困难了。该文主要讨论3种基于APA(新型聚合物结构)技术的氟弹性体,并与传统的FKM和FEPM进行了对比。为了满足高温高压油井中选择最适宜弹性体材料的需要,对室温下和200℃下的物理性能、低温弹性性能、耐化学介质性能,包括在酯类钻井液和甲酸盐中的性能变化进行了对比。同时也讨论了APA聚合物加工性能方面的改善状况。
The use of fluoroelastomers in the oil and gas industry has been steadily growing. Due to the limitations of traditional fluoroelastomers, it has become increasingly difficult to select a suitable elastomeric material to meet specific applications in today’s high temperature and pressure (HPHT) and harsh chemical media environments. This article focuses on three fluoroelastomers based on APA (New Polymer Structure) technology and compares them with the traditional FKM and FEPM. To meet the needs of selecting the most suitable elastomeric material for high temperature and high pressure oil wells, physical properties, low temperature flexibility properties, chemical resistance properties at room temperature and at 200 ° C, including performance changes in ester drilling fluids and formates Contrast. The improvements in APA polymer processing properties are also discussed.
