将出砂冷采技术应用到稠油油藏,虽然会大幅提高油井的产量,但实际生产中过度出砂或者过度防砂都会带来各类问题。为了在出砂生产和防砂之间寻求最优的解决方案,实现油井适度出砂,需要一套出砂监测系统进行实时监测,持续有效显示出砂信息,为出砂生产和防砂提供最优的策略。通过对国内外出砂监测技术的调研,总结了出砂监测的主要方法,介绍了出砂监测的主要设备,分析了监测信号的处理方法,指出了出砂监测的重要性及未来发展趋势。

Applying cold production to heavy oil reservoirs is one of the hottest technologies of the present oil exploration, which can improve the yield of oil wells substantially. However, excessive sanding can damage the production equipment while excessive sand prevention can decrease the efficiency of the yield. Both of them in actual production can bring problems. In order to seek the optimal solutions in sand production and sand prevention, and achieve sand management in oil wells, a set of sand monitoring systems for real time monitoring are needed to show sand information continuously and effectively to provide optimal strategy. According to the research of sand monitoring technology worldwidely, different sand monitoring methods such as ultrasonic methods, ER methods, surface monitoring and underground monitoring, equipments such as ClampOn system, CorrOcean system and Landy system, and signal processing methods such as FFT, WT and EMD are introduced. Characteristics of these methods and facilities are analyzed, and the importance of sand monitoring and the development trends of sand monitoring are put forward.
