| 摘 要： | 采用对数谱分析方法，利用油气层与非储层的拟频率对数谱特征上的差异，分离油气层与非储层；通过在拟频率域计算塑性能量比率、塑性与弹性能界限拟频率值等，建立了一种新的基于弹塑性能分解的能量吸收分析技术。将该技术应用于四川宣汉地区普光气田，取得了明显的效果，证实这种基于能量分解的吸收分析技术是一项较为有效的油气预测技术。

| Abstract: | The hydrocarbon reservoir and nonreservoir can be separated u-sing the logarithmic spectrum analysis method according to the quefrency characteristic difference of them. A new energy absorption analysis technology based on the decomposition of elastic and plastic seismic energy is established by means of computing the attribute in quefrency field such as ratio of the plastic energy, the threshold value of the plastic and elastic seismic energy. This technology is applied to Puguang gas field in Xua-nhan area of Sichuan,and visible application effect shows that the absorption analysis technology based on energy decomposition is one of more effective technologies for hydrocarbon prediction. |
