CONTROLLING FACTORS FOR GAS ACCUMULATION IN KONGQUETING GAS FIELD OF XIHU SAG
-
摘要: 综合运用地质、钻井、生物标志物、碳同位素、储层流体包裹体等资料,在油气分布特征和来源分析的基础上,探讨了控制西湖凹陷孔雀亭气田油气成藏及富集的主要因素。研究结果表明,孔雀亭气田油气主要分布在始新统平湖组储层内,具有"上油下气"的纵向分布特征,以断块型凝析气藏为主,原油及天然气来源于自身和西部次洼平湖组源岩联合供烃。孔雀亭气田油气成藏及富集主要受断层封堵性、砂体厚度和储层物性及流体充注历史的联合控制,断层封堵性控制了油气藏的含油气性,砂体厚度和储层物性制约了油气层厚度和含油气饱和度,流体充注历史决定了油气藏的现今赋存相态。Abstract: Based upon the integration of geological, drilling, biomarkers, carbon isotope, fluid inclusion data and the analyses of the oil and gas distribution pattern and the sources of oil and gas, the controlling factors for hydrocarbon accumulation in the Kongqueting gas field are discussed. Research results show that the oil and gas are mainly distributed in the Eocene Pinghu Formation, in a vertical pattern with oil lying upon gas. It is mainly a block-type condensate gas reservoir. Oil and gas are mainly contributed by both the local deposits and the deposits in the western sub-depression of the Pinghu Depression. The accumulation of oil and gas is mainly controlled by fault sealing, changes in sand body thickness and reservoir property and fluid filling history. The fault block controls the sealing condition of the reservoir, sand body thickness and reservoir properties restrict the oil and gas saturation, and the fluid filling history determines the current phase occurrence of oil and gas.
