In this paper, Rock\|Eval, Py\|GC and simulation experiment via an open\|system were used to study the hydrocarbon\|generating potential, hydrocarbon composition, and hydrocarbon\|generating model of barkinite\|rich coals from the Shuicheng coal field of Guizhou Province, Southwest China. The results show that barkinite\|rich coals have high hydrocarbon\|generating potential, with S\-1+S\-2 being 211-311mg/g, and can produce large amounts of hydrocarbon at the high\|maturity stage, mostly within the temperature range of 420-450℃ (corresponding to VR\-0 1.1-1.5%); barkinite\|rich coal is one of the better oil sources and light hydrocarbon and wet gas are the major hydrocarbon components, which account for 45% and 33% of the total hydrocarbons, respectively. These characteristics are of importance for exploring oil and gas resources in the Late Permian Longtan Formation coals, Southwest China.\;展开更多
