海上压裂设备作为海洋油气资源增产作业的关键设备之一,在保证高效、安全运行的同时,其噪声问题对设备与从业人员也产生重要影响。以某型号橇装式海洋油气压裂设备为研究对象,对噪声数值模拟和测试方法进行研究,建立橇装式海洋油气压裂设备三维模型、压裂设备整机有限元模型和压裂设备边界元网格模型;利用Virtulal.Lab Acoustic对压裂设备整机辐射噪声进行预测,获取压裂设备声场声压云图及噪声显著频段;通过对压裂设备进行噪声测试,确定出不同工况下各测点的最大声压级、总声压级、平均声压级和声功率级。研究结果分析出压裂设备辐射噪声的显著频段,压裂设备噪声呈明显的宽频特性,泵头处噪声较为显著。将数值仿真结果与噪声测试结果进行对比,验证了仿真分析结果的准确性。仿真分析所得结果为压裂设备后续优化设计和噪声控制提供了指导和参考。

Offshore fracturing equipment as one of the key equipment for offshore oil and gas resources production enhancement operations,has an important impact on the equipment in terms of noise issues while ensuring efficient and safe operation.With a type of skid-mounted offshore oil and gas fracturing equipment as an example,noise numerical simulation and testing was conducted.A three-dimensional model of the skid-mounted offshore oil and gas fracturing equipment,a finite element model of the whole fracturing equipment and a boundary element mesh model of the fracturing equipment were established.The Virtulal.Lab Acoustic was used to predict the overall radiated noise of the fracturing equipment so as to obtain a sound pressure cloud of the sound field of the fracturing equipment and the significant frequency bands of the noise.The maximum sound pressure level,total sound pressure level,average sound pressure level and sound power level of each measurement point under different working conditions were determined by noise testing of fracturing equipment.The significant frequency band of fracturing equipment noise was analyzed,and the noise of fracturing equipment has obvious broadband characteristics,and the noise at the pump head is more significant.The numerical simulation results are compared with the noise testing results to verify the accuracy of the simulation analysis results.The results of simulation analysis provide guidance and reference for the follow-up optimization design and noise control of fracturing equipment.
