摘要
APR-N阀是哈里伯顿公司全通径压控式测试工具的主阀。全通径选择测试阀作为新一代的压控式测试阀,较以往使用的APR-N阀在结构、性能、原理上有了较大改进,拓宽了地层测试的使用范围,降低了井筒及其它因素与外界影响,使得现场测试更加简便、安全、可靠。但经过多次现场使用,证实全通径选择测试阀还存在某些不足,需要进一步完善和改进。
APR-N testing valve is the main valve of full bore pressure controlling tools in Harlliborton's company.Selective testing valve,being a new generational one,is developed in structure,performance and principle that expands applied scopes of formation testing,decreases influences of bore hole and other factors to outer world to make field operation to be handy,safe and reliable.But by many times of field applications,some shortages for bore hole selective tester is tested which needs a good completion and development.
