当今时代对能源的需求日益增长,这就要求在寻求石油与天然气方面要有新的和变革性的措施。在以前低油价的时期,由于出油量低或是商业化程度低,许多油井都被关闭了,而当前的油价空前的高涨,因此这些油田资产变得更有生存能力,虽然如此,但仍然需要一个能够吸引人的商业解决方案来使这些油田有利可图,并满足一些特殊的需求,迎接各种各样的挑战。 相似文献

Vehicle dwell times are perhaps the most unpredictable parameters of station operations because of occasional passenger intervention. This paper reports on an investigation involving theoretical and Monte Carlo techniques to ascertain the sensitivity of station throughput to randomness in dwell times. Alternative configurations of vehicle loading positions, e.g., loading positions in parallel, in series, or in a series-parallel combination, are considered in an effort to rank the configurations by their associated performance levels. 相似文献

The cryogenic ground support equipment (CGSE) is an important part of Alpha Magnetic Spectrometer-02 (AMS-02) experiment which
is a particle physics experiment. CGSE is used to cool down the superconducting magnet of AMS-02 to its operating temperature
of 1.8K and to fill the magnet helium tank with superfluid helium. This paper introduces the control system of CGSE and presents
the performance of the system. 相似文献
