【摘要】 |

Deep-seated gas is defined in this paper as natural gas generated under the combined action of high temperature, high pressure, and environment media. As to organic matter vertical evolution, deep-seated gas is natural gas, which is generated and deposited under the position of an oil generation window. Deep-seated gas exploration is an important potential field for oil-gas exploration. Also, it is an inexorable trend to the further development of oil and gas provinces. In this paper, the authors will examine and distinguish the concept of deep-seated gas, and discuss the distribution and gas source of deep-seated gas. It is pointed out that kerogen, assemble dissoluble organic matter and disperse dissoluble organic matter all have contributed to deep-seated gas generation, especially disperse dissoluble organic matter in composite and superimposed sedimentary basin. In the end, according to the structural evolution and hydrocarbon source rock depositional distribution, the distribution of deep-seated gas in China is predicted. |
