除了产量数据之外,识别油井流体,对于采油工程师或油藏工程师变得越来越重要。
流体识别除了持水率外,主要是流体密度测量。
目前使用的流体密度测量方法有放射性密度和压差密度。
fdi 音叉密度仪是sondex公司生产的新型流体密度测量仪,测量精度高,稳定性好,可进行连续测量。
1 fdi仪器结构与参数fdi仪器主要由两部分组成,分别是电子线路部分与测量探头部分。
探头部分包括两个探头,分别是温度探头和音叉探头。
电子线路部分有3块pcb电路板。
通讯/电源电路板控制仪器内部电源供给,完成仪器通讯,采集数据;振荡器电路板通过一个压电晶体管来驱动并维持音叉的谐振,并产生两个输出信号:谐振频率与振动幅度;模拟电路板接受温度探头数据和振动幅度数据,并进行a/d 转换。
具体各部分工作状况见图1。
图1?fdi仪器工作框图fdi仪器主要参数如下:外径:1-11/16”(42.86mm)长度:20.55”(521.97mm)质量:7.81lb(3.54kg)耐温:150℃耐压:15000psi测量范围:0-1.25g/cc测量精度:±0.03g/cc分辨率:0.01g/cc响应时间:<1 seconds2 音叉密度仪测量原理音叉密度传感器是由音叉体、固支体、压电晶体管和温度传感器组成的。
音叉是呈“y”型的不锈钢发生器,其两臂对称,振动相反,中心杆处于振动的节点位置,静受力为零,不振动,因此固定在固支体上。
温度传感器贴装于固支体上,实时检测被测液体温度,用于补偿调谐叉体的弹性模量变化。
压电晶体管包括压电激励器和压电拾振器,均贴装在固支体上。
音叉谐振式黏密度计计量性能及校准方法

国内统一刊号CN31-1424/TB2020/5 总第282期音叉谐振式黏密度计计量性能及校准方法文慧卿 金愿 陈超云 朱绚华 / 上海市计量测试技术研究院摘 要 介绍了一种可对各类混合相液体进行黏度密度同时在线测量的方法,基于音叉谐振式原理的新型黏密度测量仪表,并通过实验分析其各项计量性能,探讨该仪器的校准方法,可以为黏密度测量行业计量校准工作提供参考。
关键词 音叉谐振式;黏度计;密度计;校准0 引言黏密度测量是石油化工、生物医药、食品能源以及国防等领域控制生产流程、保证生产安全、评定产品质量及科学研究的重要手段。
传统黏度测量方法主要包括毛细管法、旋转法、落球法、振动法[1],密度测量方法主要包括阿基米德法、等体积法、等质量法、压差式、超声波式[2],以及在此基础上为满足特定要求而进行的诸多方法优化。
传统的黏密度测量方法只能测量纯净液体,不能同时测量液体黏度和密度,最主要是不能在线测量,并且具有很大的局限性,对于泡沫非牛顿液体或含气泡等混合相液体无法进行测量。
现在市场上有一种基于音叉谐振原理的黏密度计,其利用音叉谐振原理测量液体谐振频率,从而获得液体的黏度与密度。
因其性能稳定且适用于小孔径的场合,能够适用于容量极少、黏度很低甚至含泡沫的非牛顿液体或含有固体或气泡等混合相液体的在线黏度与密度测量,而被广泛研究和应用[3-4]。
鉴于尚无针对这种黏密度计的校准方法,本文通过实验及误差分析,评估了这种音叉谐振式黏密度计的实际计量性能状况,在此基础上探讨其校准方法。
1 仪器测量原理音叉谐振式黏密度计主要由音叉、激振单元、拾振单元构成,是利用一个压电晶体产生的谐振频率,再通过音叉头另一个压电晶体测量其谐振频率。
当液体流动经过音叉时,受液体黏度、密度的影响,被测液体对音叉的阻尼大小不同,通过音叉传感器谐振频率的变化反应液体的黏度与密度,其工作原理如图1所示。
图1 测量液体黏度与密度的原理图2为音叉的单个叉体等效模型,经理论推导结合实验研究[5],可知液体附着在叉体上的有效质量总和Δm 为Δm = 0.6λρ(ac ρηω2ac (1)式中:Δm —— 附着在叉体上的液体有效质量总和;a 、b 、c —— 叉体尺寸; λ —— 叉体的有效质量; ρ —— 液体密度; η —— 液体黏度; A—— 振幅; ω —— 叉体谐振频率根据式(1)可以计算出音叉改变后的谐振频率f '为f 'f (1 - 21Δmm g ) (2)10国内统一刊号CN31-1424/TB 2020/5 总第282期式中:f ' —— 改变后的谐振频率;f —— 改变前的谐振频率; mg —— 悬臂梁的有效质量; k—— 与叉体尺寸相关的常量图2 单个叉体的等效模型引起音叉传感器谐振频率变化的主要原因是不同的液体附加在叉体上的有效质量不同,液体附加在叉体上的有效质量不仅与音叉的外形、尺寸有关,而且与液体的黏度和密度有关。
