摘要/Abstract

摘要： 运用CFX和ANSYS Design Exploration,采用中心组合法和响应面法计算了新型控压钻井节流阀阀盖长度、阀盖外径、阀腔内径单一参数和双参数关于阀芯平均质量损失的克里金响应面,结果表明这些尺寸对阀芯的平均质量损失影响显著。为增强阀芯耐冲蚀性,提高节流阀使用寿命,采用多目标遗传算法对上述尺寸进行了优化。优化后阀芯的平均质量损失减弱30.2%,阀芯对称面轮廓线上各点随x坐标冲蚀率的变化表明大部分点冲蚀率有明显减弱,阀芯背部冲蚀率减弱最显著。

Abstract: The Kriging response surface of single parameter and double parameters versus mass loss of valve spool about bonnet length, bonnet external radius and chamber inner radius of a new type throttle valve used in Managed Pressure Drilling was carried out by using CFX and ANSYS-Design Exploration. The results show that these dimensions have significant influence on erosion mass loss of valve spool. In order to improve the anti-erosion ability of the spool and enhance the service life of the whole valve, the multi-objective genetic algorithm was used for dimensional optimization design of the mentioned variables. After optimization design, the averaged erosion mass loss of plug was decreased 30.2% than that in original chamber dimensions. The detail analysis of spool contour in symmetry plane indicates the erosion rate of majority points on the contour are decreased obviously, and especially significant at the back side of the spool.

Key words: throttle valve of managed pressure drilling, spool erosion, response surface methodology, optimization design, computational fluid dynamics
