摘　　要：为提高滩海油田海底管道和陆岸管道油气泄漏监测的有效性,选用了次声波法对上述管道的泄漏进行现场监测试验。试验设计了30、20、10、5、3 mm孔径的孔板,用于模拟管道上不同的泄漏点,并分别研究了油、气、水多相流海底管道和油水两相流陆岸管道泄漏的次声波法监测的可行性。研究表明,对于油、气、水混输管道,管道两端的传感器不能接收到清晰的泄漏次声波信号;对于油,水混输管道,管道两端的传感器可以接收到泄漏的次声波信号,且泄漏点孔径越大,次声波的信号越强,但对于泄漏孔径≤3 mm的管道,其泄漏所产生的次声波信号不能被位于管道起点和末点的传感器监测到。In order to improve the effectiveness of oil and gas leakage monitoring for submarine pipeline and land pipeline in seabeach oilfield,the infrasound method was selected to carry out field monitoring test of the pipeline leakage.The flange covers of φ30,20,10,5 and 3 mm were designed to simulate different leakage points on the pipeline,and the feasibility of using infrasound method to monitor the leakage of the submarine oil,gas and water multiphase flow pipeline and the land oil and water two-phase flow pipeline was investigated respectively.The results show that the sensors at both ends of the pipeline can not receive a clear leaking infrasound signal of the oil,gas and water multiphase pipeline,but the sensors at both ends of the pipeline can receive the leaking infrasound signal of the oil and water two-phase flow land pipeline,and the larger the aperture of the leaking point is,the stronger the signal of infrasound is.However,for a pipeline with a leakage aperture of less than 3 mm,the infrasound signal generated by its leakage cannot be monitored by sensors located at the starting point and the end point of the pipeline.
