A simple and efficient improvement on the conventional packer testing technique is described. Based on experience associated with hundreds of packer tests in the past decade, a functional change is proposed with respect to the pressure inflation supply for the packer testing unit. The change involves allowing each packer to be independently controlled with two separate gas-flow delivery systems, allowing for independent inflation and decompression underground. Four types of packer set-up are presented, which are able to be used alternately, according to specific environmental needs. It is believed that this is a small but important technical solution for packer testing failures, particularly as regards low water-level conditions in the well, regardless of whether this is a natural effect or a result of the drilling operation.

描述了对常规封隔器测试技术的简单有效的改进。根据过去十年中数百次封隔器测试的相关经验，提出了针对封隔器测试单元的压力充气供应进行功能更改的建议。更改涉及允许每个封隔器由两个单独的气流输送系统独立控制，从而实现地下的独立充气和减压。介绍了四种类型的封隔器设置，根据特定的环境需求，它们可以交替使用。可以相信，对于封隔器测试失败，这是一个很小但重要的技术解决方案，尤其是在井中水位较低的情况下，无论这是自然影响还是钻井操作的结果。
