一种能有效监测稠油出砂信号的室内实验装置设计

An Effective Experimental Device Design for Monitoring the Sand Signal Out of the Heavy Oil

稠油油井生产的适度出砂开采技术需要一种有效简便的出砂实时监测方式来监测油井生产的出砂状况。油井的过度出砂能严重损坏设备,影响生产。国内目前油井的出砂监测方法主要包括出砂声测法和电阻法,但是这两种方法对于稠油的出砂监测都存在一些问题。因此,实验室内设计了一种用于稠油出砂监测的一次仪表,主要是通过采用压电式高频加速度传感器来接收携砂流体中砂粒撞击管壁产生的振动信号来监测稠油的出砂状况。为验证这一装置设计的有效性,在实验室内建立了一套完整的稠油出砂监测系统。实验采用150目石英砂粒,含砂量从0‰到5‰,利用高黏度的齿轮油作为携砂流体。实验结果表明,这种一次仪表设计能够有效实时监测稠油的出砂信号,具有很好的应用性。

The moderate sand mining technology of heavy oil field need a kind of effective and sample real-time monitoring system for monitoring the signal of sand out, over sand can damage the device severely , affecting pro-duction. Sand monitoring methods include sand acoustic method and resistance method, but there are some prob- lems in these two methods, so a method is designed for heavy oil sand monitoring instrumentation through the use of the piezoelectric high-frequency acceleration sensor to receive the sand hit the wall in sand-carrying fluid vibration signals to monitor the status of the heavy oil out of sand. In order to verify the effectiveness of the design, a com-plete is established set of heavy oil sand production monitoring system in laboratory. Using 150 mesh quartz sand, the sand content from 0‰ to 5‰, with high-viscosity gear oil as a sand-carrying fluid. Experimental results show that this design can effectively monitoring the sand signal from heavy oil real-time, with a good effect.
