| 摘 要： | 以吉林省境内红星构造带(已发现油田)和杨柳青构造带(未发现油田)为试验区,首先利用地震地层学方法,研究间接参数特征,确定有利相带和有效圈闭,并在有效圈闭上选择了39个2×2cm时窗。在时窗内提取与地震波动力学有关的信息,即频率、振幅、频谱能量等,然后对这种信息进行统计计算,获得振幅方差等九个参数并对其进行综合分析,从已知油气藏出发,对未知圈闭油气状况进行了三级预测,指出了最有利的勘探靶区。

| Abstract: | In the earlier of 1980's,the authors suggested to use the more parameters of geophysics, geochemistry and peotroleum geology to forecast ioil and gas accumulation. We call this technology in short form. This kind of technology is multipuposely use the method of seismic'stratigraphy to study the condition of reservoir and traps synthetically and caculate them. Finally, we study the more parameters with the aid of method of mathematical statistics. In this way, we build up a discriminant model for the forecasting of oil and gas accumulation.We select two structual zones of Hongxing (known oil field) and YangliuqingCunknown oil field)as test areas. Firstly, favorable facies zone and effective traps are determined through the study of indirect parameters by using the method of seismic stratigraphy,then thirty-nine "time windows" with the size 2cmx2cm each of which are selected from the effective traps.The information related to seismic wave dynamics,such as,frequency,amplitude and frequency spectrum enery are collected within the "time windows". Finally, nine parameters including amplitude deviation are abstracted by statically calculation of these information.Based on the result of synthetically analyzing of the nine parameters and the known hydrocarbon reservoir,third level of prediction for hydrocarbon accumulation is made,and the most prospective target for exploration is suggested |
