摘　　要：选用通过国家级计量认证的一等活塞式压力计标准装置和二等水银温度计标准装置 ,自行设计配套试验组件 ,模拟测试井实际情况 ,研究不同直径的黄铜材质销钉在常温常压、高温高压状态下 ,温度对其剪切压力的影响程度 ,并验证APR测试器使用说明书中有关黄铜销钉在高于30 0 (15 0℃左右 )时出现塑流的真实性。试验表明 :销钉随温度升高 ,其剪切压力小 ,幅度逐渐减小。高温时间长短对剪切压力无明显影响 ,以及在 15By use of the standard equipment of the first grade piston pressure gauge and the second grade mercury thermometer which passed national metering certification,a set of testing component has been designed and by analog actual testing situation,the paper studies the effect of temperature to shear pressure of shear pin at state of constant temperature and pressure or high T & P for different diameter yellow brass that certifies the reality of it appearing plastic flow when temperature is much higher than 300 Fahrenheit on Halliburton instruction manual about APR tester.By studying on the test,it is drawn a conclusion that shear pressure of brass decreased slightly with higher temperature and without obitvious influence to it for long or short of being high temperature and the brass has not plastic flow over 300 Fahrenheit.
