摘要
济阳坳陷浅层广泛分布着"亮点"型气藏,约有700×108m3的中、浅层天然气有待探明。从济阳坳陷浅层气藏成藏条件入手,分析了控制天然气成藏分布的气源、构造、盖层等因素,对气藏进行了三维地震描述。根据亮点的形成机制及影响因素,提出了应用弹性能/塑性能、能量吸收、AVO及反射波多参数提取等多种预测技术判识气藏,总结了一套行之有效的工作流程及方法,在天然气勘探开发中应用效果显著,此项技术可推广应用于渤海湾断陷盆地浅层气藏的勘探开发中。
Highlight type of gas reservoirs were widely distributed in the shallow strata of Jiyang Depression.There were still about 700 × 108m3 middle and shallow natural gas to be proven.Therefore,based on shallow gas reservoir forming conditions,the factors controlling the gas reservoir formation,such as gas source were analyzed,its structure and caprock and 3D seismic description was performed on the gas reservoir.According to the reservoir formation mechanism and influencing factors of the highlight,several forecasting techniques are proposed for predicting gas reservoirs by using the method of elastic energy / plastic energy,energy absorption,AVO and as well as the reflected wave multi-parameter extraction etc.,up a set of effective working flow processes and methods are summed up,the methods are used in natural gas exploration and development with good effect.
