| 摘 要： | 塔河油田碳酸盐岩储集层埋藏较深,一般都在5000m以下,储集层主要为碳酸盐岩裂缝和溶蚀缝洞系统,纵横向非均质性强,储集层横向预测困难.本文介绍了小波变换的基本理论,利用小波变换的局部化分析特征引入吸收衰减分析技术中,根据塔河油田奥陶系碳酸盐岩储层情况设计了接近实际深度的理论模型,并对模型正演结果进行了吸收衰减分析,验证了其可行性,最后对塔河油田实际数据进行处理,含油气性预测结果跟实际钻井非常吻合,证实了方法的有效性.

| Abstract: | Tahe oilfield's carbonate reservoir is buried deeply with normal depth over-5300m.The dominated system of carbonate fractures and corrosive caverns and serious heterogeneity in plane and vertical results in difficulty for transverse prediction of the reservoir distribution.The Paper expatiated basic theories and principles of wavelet transform and introduced the absorption and attenuation technology by wavelet transform.Theoretic model near real deep based on the geological analysis results was made to prove the feasibility of absorption and attenuation.Finally,this technology was applied to actual seismic data in Tahe oilfield,and the predicting results for oil and gas accorded with the drilling result. |

| Keywords: | Tahe oilfield absorption and attenuation wavelet transform carbonate reservoir prediction |
