    Abstract: In the process of oil field development, the law of water cut is usually described by exponent model, but during the early water breakthrough stage and ultra-high water cut stage, relative permeability ratio of oil to water (Kro/Krw) and water saturation (Sw) is no longer linear relations in semilog coordinate, so it has an important influence on w...

    Abstract: In order to evaluate and give a early-warning about the gas outburst risk during excavation, comprehensive indexes used to evaluate the gas outburst risk are put forward and a gas outburst early-warning model based on the normal distribution function (2σ) is created; a typical working face with gas outburst risk in Xinzhuangzi Mine of Huainan...
