摘　　要：针对常规测井用集流器存在的漏失、易刮破等问题,提出一种以橡胶弹性件为核心的电动挤压式橡胶集流器整体方案。该方案利用有限元法和Mooney-Rivlin超弹性本构模型,对所提橡胶弹性件进行仿真,研究了其形状、几何尺寸以及材料属性等对集流性能的影响规律。研制了电动挤压式橡胶集流器,在模拟井实验平台上测试其集流性能。实验结果表明,橡胶弹性件形状、硬度、与套管之间的摩擦系数、内凹程度均对其受力形变性能有显著的影响;采用硬度58HA、尺寸80 mm×12 mm、内凹量4 mm、圆弧内凹型弹性件的橡胶集流器,其集流性能优于常规伞式集流器。Aiming at the problems of leakage and scraping of conventional oil logging flow collectors,an overall scheme of electric extruded rubber flow collector with rubber elastomer as the core is proposed.The finite element method and the Mooney-Rivlin hyperelastic constitutive model are used to simulate the rubber elastomer and study the influence of its shape,geometry and material properties on the flow collection performance.Moreover,an electric extruded rubber flow collector is developed and its flow collection performance is tested on a simulated well test rig.Experimental results demonstrate that the structure,hardness,friction coefficient with the pipe and the concave degree of the rubber have a significant influence on the performance of the collector;The rubber flow collector with hardness 58HA,size 80 mm×12 mm,4 mm internal concavity and rounded internal concave elastomer has better flow collection performance than conventional umbrella type flow collector.
