【摘要】 花沟地区天然气藏类型多,有甲烷气藏、二氧化碳气藏,以及甲烷、二氧化碳和氮气的混合气藏,含气层系多且分布复杂。天然气藏受气源条件和构造控制,形成独特的天然气分布规律及强振幅亮点型、平点型、下凹型地震反射模式。分析了该区天然气藏的分布规律和不同气藏的地震反射模式,建立气藏地震识别标志,并在实际应用中取得良好效果。更多还原

【Abstract】 There are many types of gas reservoirs, such as reservoirs of methane and carbon dioxide, as well as combined gas reservoirs of methane, carbon dioxide, and nitrogen in Huagou area. These gas reservoirs are in complex series of strata. Controlled by source conditions and structures, theses gas reservoirs have unique distribution regularities and display different seismic reflection patterns such as bright spot, flat spot, and concave. By analyzing the distribution and seismic reflection patterns of gas reservoirs in Huagou area, we establish seismic i-dentification marks of gas reservoirs. Desired results have been achieved.更多还原
