摘要:
 套管测试封隔器胶筒受耐温、耐压限制，不能满足超深储层的安全测试。可回收悬挂式封隔器符合API 11D1V3 级别，耐温204 ℃、耐压105 MPa，自带同心旁通机构，减少了封隔器起下钻抽汲及锁定机构，可以避免下钻过程中因套管壁的摩擦阻力使外筒串上移；优选AFLAS材质，在密封胶筒两端增加护肩组合三胶筒结构，提高了封隔器的密封压差。室内按照API 11D1V3级别进行正反向压力反转测试及现场试验。结果表明，在高温高压环境下封隔器坐封可靠，加压至105 MPa时验封合格。该封隔器可满足高温高压超深井试油测试需要，为超深井试油测试提供了技术支撑。
Abstract:
 The rubber cylinder of 1397 mm casing test packer cannot meet the safety test requirements of ultradeep reservoir limited by its temperature resistance and pressure resistance properties. According to the test, the retrievable hanging packer meets standards of the API 11D1V3 level, whose temperature resistance is 204℃ and pressure resistance is 105 MPa. It is equipped with concentric bypass mechanism, which reduces the tripping swabbing and locking mechanism of packer to avoid the upward movement of outer barrel string due to the friction resistance of casing wall during tripping. In addition, AFLAS material and adding a shoulder protection combined three rubber cylinder structure at both ends of the sealant cylinder improve the sealing differential pressure of the packer. Indoor forward and reverse pressure reversal test according to API 11D1V3 level and field test show that the packer is reliable under high temperature and high pressure, which is qualified when pressure improve to 105 MPa. The packer can meet the requirements of oil testing in high temperature and high pressure ultradeep wells and provide support for the development of oil testing technology in ultradeep wells.
