中文摘要:
      目的 为东海某气田封隔器胶筒橡胶材料的选择提供理论参考依据。方法 通过腐蚀前后的性能试验和在腐蚀介质中的渗透性试验,比较目前国内外封隔器胶筒使用的主要橡胶材料(氢化丁腈橡胶、氟碳橡胶、氟硅橡胶和AFLAS橡胶)在腐蚀后的拉伸强度、拉断伸长率、硬度、压缩永久变形等性能,以及在腐蚀介质中的渗透性。结果 性能最优秀的是氢化丁腈橡胶,其次是AFLAS橡胶,氟硅橡胶和氟碳橡胶性能较差。随着压差的增大,4种橡胶材料的抗渗透性变差,相同温度(120 ℃)下,氟硅橡胶在4个压力条件下的抗渗透性能均优于其他橡胶材料。随着温度的增加,4种橡胶材料的抗渗透性变差,相同压差(10 MPa)下,氟硅橡胶在4个温度条件下的抗渗透性均优于其他橡胶材料。结论 氢化丁腈橡胶的性能(拉伸强度、拉断伸长率、硬度和压缩永久变形)相对较好,次之是AFLAS橡胶,再次是氟碳橡胶和氟硅橡胶。温度对橡胶渗透性的影响比压差大,对某些橡胶而言存在阀值效应,当超出一定温度后,橡胶抗气体渗透性能迅速下降。因此,应根据服役环境合理选择橡胶材料,且尽量使封隔器胶筒处于应力平衡状态,延长井下工具安全服役寿命。
英文摘要:
      The work aims to provide theoretical basis for selection of packer cartridge rubber material in one gas field of the East China Sea. The tensile strength, elongation at break, hardness and permanent compression deformation after the corrosion and permeability in corrosive medium of the major rubber materials used in China (like hydrogenated nitrile rubber, fluorocarbon rubber, fluorine and silicone rubber and AFLAS rubber) were compared through the performance test after the corrosion and the permeability test in corrosive medium. By comparison, hydrogenated nitrile rubber was the best, and then followed by AFLAS rubber. Fluorine and silicone rubber and fluorocarbon rubber performed poorer. The impermeability of four kinds of rubber materials became bad as the differential pressure increased. The impermeability of fluorine and silicone rubber was better than that of all the other materials in four pressure conditions at the same temperature (120 ℃). The impermeability of four kinds of rubber materials became bad while the temperature increased, the impermeability of fluorine and silicone rubber was better than that of all the other materials at four different temperature in the same differential pressure (10 MPa). The performance (tensile strength, elongation at break, hardness and permanent compression deformation) of hydrogenated nitrile rubber is relatively better and then followed by AFLAS rubber. Fluorine and silicone rubber and fluorocarbon rubber are the poorest. Temperature has bigger effect on permeability of rubber than differential pressure, and there is a threshold effect for some rubber materials. The gas impermeability of rubber can rapidly decrease when certain temperature is exceeded. Therefore, in order to extend the safe service life of downhole tools, the rubber materials should be chosen according to the service environment, and the packer cartridge should be kept in stress equilibrium as far as possible.
