The trans-media transmission of quantum pulse is one means free-space which can be applied in continuous-variable key distribution (CVQKD) system. In traditional implementations for atmospheric channels, the 1500-to-1600-nm regarded as an ideal carrier. However, underwater this pulses tends to suffer from severe attenuation, inevitably deteriorates security whole CVQKD paper, we propose alternative scheme over satellite-to-submarine channels. We estimate parameters involving atmosphere, sea...

During the development of M gas reservoir which is a typical fracture-pore carbonate with bottom water, excessive water production frequently encountered during lifetime gas-producing wells, generally results in rapid productivity decline and remarkable increase operating costs caused by handing treating large amount water.
