【Abstract】 The data of Keyi structure about tectonic movements during the Mesozoic-Cenozoic period was synthesized and the development history of the basin and the structure was characterized. Studies on reservoir fluid inclusions, geothermal anomaly, gas accumulation patterns and hydrocarbon expulsion from source rocks show that the gas accumulation occurred episodically in the Kela-2 Gas Field, which lies on Keyi structure. It is inferred that the episodic tectonic actions of the Keyi structure lead natural gas fill episodically in the traps of the Kela-2 Gas Field.更多还原
