Downhole Gas Compressor Motor Drive for Production Enhancement from Gas Fields

此次S2B合作的重点是创新的集成电力电子矩阵转换器（IPEMC）的设计、开发和工程，用于驱动大功率永磁无刷电机。关键的发明步骤包括消除所有笨重的电感，传统上用于形成新的交流波形，使用新颖的逆变器和控制拓扑。对于井下气体压缩机（DGC）应用来说，它是一项关键的使能技术，在这种应用中，机器必须在极端恶劣的环境中在极小的空间范围内运行。通过在井下定位DGC，并在储层附近进行压力提升，可以实现产量的大幅提高（范围为28-42%），并显著提高最终采收率（UR）。这个独特的项目为所有工业应用带来了电力电子设备的显著小型化，同时也提高了高温性能和坚固性，并减少了电磁辐射。

This joint S2B collaboration is focussed on the design, development and engineering of an innovative Integrated Power Electronic Matrix Converter (IPEMC) for driving high power permanent magnet brushless motors. The key inventive step involves the elimination of all of the bulky inductors that conventionally are used to shape the new AC wave form, using a novel inverter and control topology. It is a key enabling technology for the Downhole Gas Compressor (DGC) application where the machine must operate in an extremely small space envelope in a hostile environment. By being able to locate the DGC down hole and pressure boost close to the reservoir, large increases in rates of production (in range 28-42%) are achievable as well as significant increases in Ultimate Recovery (UR). This unique project results in significant miniaturisation of the power electronics for all industrial applications, while also increasing high temperature performance and ruggedness and reducing EM radiation.
