摘要
针对大庆火山岩储层特性,改进了高温高压双封封隔器胶筒橡胶件,研制一种双马来酰亚胺(BMI)改性氟橡胶高性能材料,将其作为封隔器胶筒的主体材料。改进后的封隔器能够满足最大下深4500 m、最高温度180℃、最大压差60 MPa的储层试气施工。通过室内试验和3井次现场施工,均获成功。
According to the characteristics of volcanic rock reservoirs in Daqing,we improved the high temperature and high pressure double packers glue tube rubber parts,and developed a BMI modified fluorine rubber high performance materials,which was used as main materials of the packer's glue tube.The improved packer could meet the need of reservoir try gas construction with maximum depth of 4500 m,the highest temperature of 180℃,and maximum differential pressure of 60 MPa.Both the laboratory test and 3 wells site construction showed great success.
