摘要
在抽油井环空测试过程中 ,防喷装置是保证油井压力稳定不变的重要设备。我国经过二十多年的努力 ,先后研制成功“直立式”、“倾斜式”、“纳入式”和“可放式”等多种结构的环空测试防喷装置。文中详细介绍了各环空测试防喷装置的结构、原理和操作要点 ,并针对各自不同的特点 。
In the process of annulus test of pumping wells,blow-out preventer is an important equipment to ensure stablepressure in the well. Through more than twenty years efforts,our country has successively developed the blowout preventers for annulus test with different kinds of structures such as' vertical type','slant type','place-intype',' lay-down type'. This paper details their respective structure, working principle and main operatingpoints,and analyzes existing problems in accordance with their different charateristics.
