摘　　要：新型扩张式封隔器的生产应用需通过多项关键性能测试,为保证其工作表现,提出了一套扩张式封隔器性能评价方法。以行业标准为基础,结合工程经验制定了扩张式封隔器的测试流程和评价标准,同时研制了一套测试工具为室内试验提供条件。评价内容包括封隔器本体验漏、坐封与解封性能测试、胶桶疲劳测试、环空密封性能测试等。该方法流程安排合理,被测对象一次装入可完成坐封、解封及胶筒疲劳性能3项测试,避免了多余拆装过程。试验结果表明,该评价标准具有较高可靠性,通过测试的扩张式封隔器在应用中稳定可靠。通过测试的扩张式封隔器已成功应用于渤海油田50口井次,成功率为100%,平均有效期为36个月。The new expansion packer needs to pass several key performance tests in production to ensure its performance.A set of performance evaluation method for the expanded packer is presented.Based on industry standard and engineering experience,the test procedure and evaluation standard of the expanded packer are developed,and a set of test tools are developed to provide conditions for laboratory test.The evaluation content includes packer experience leakage,setting and unsealing performance test,rubber drum fatigue test,annulus sealing performance test,etc.The method has a reasonable flow arrangement,and the tested object can be loaded once to complete three tests of setting,unsealing and rubber tube fatigue performance.Unnecessary disassembly and assembly process are avoided.The test results show that the evaluation standard has high reliability and the tested expansion packer is stable and reliable in application.The tested expansion packer has been successfully applied to 50 wells in Bohai Oilfield with a 100%success rate and an average validity period of 36 months.
