| 摘 要： | 为了定量研究徐家围子断陷不同储量丰度气藏形成条件,利用气藏解剖和成藏条件时空匹配关系对该断陷气藏形成的主控因素、形成条件和储量丰度进行了研究,得到源岩供气能力、断裂输导天然气能力和封盖保存能力是气藏形成的3个主控因素.沙河子组源岩供气能力以较好和差为主,断裂输导天然气能力以好为主,封盖保存能力也以好为主.气藏形成条件综合评价以中等气藏为最多,其次是形成条件为好的气藏,差形成条件的气藏最少.气藏以中等储量丰度为主,高和低储量丰度气藏较少;二者之间为正比关系.要形成高储量丰度的气藏,气藏形成条件综合评价应为好等级;要形成中等储量丰度的气藏,气藏形成条件综合评价应为中等等级.

| Abstract: | In order to study the formation conditions of the different reserve abundance of gas reservoirs quantitatively,main controlling factors for formation of gas reservoirs,formation conditions of gas reservoirs and reserves abundance are studied by dissection of gas reservoirs and matching relations among accumulation conditions of gas reservoirs,and concluded supply gas capacity of source rock,transporting gas capacity of fault and seal and preservation ability of gas reservoirs are 3 main controlling factors ... |
