| 摘 要： | 辽河西部凹陷是辽河拗陷主要的生油凹陷.随着勘探程度的提高，勘探难度不断增大，近年来对辽西凹陷鸳鸯沟和清水洼陷坡折带以下的岩性油气藏勘探需求日益旺盛.通过双相介质油气勘探方法，利用小波变化时频分析特性，提取地震波能量和频率成分，对工作区内探井频谱特征进行了样本学习，总结出了区内高产井和无油井的频谱特征，预测出勘探风险区域的油气富集程度，再结合地球物理反演技术，明确了下一步岩性圈闭的勘探潜力区域，以降低勘探风险.

| Abstract: | The Liaoxi sag is the main oil source area in Liaohe Depression. With the improvement of prospecting level, the exploration becomes more difficult. Accordingly, there is an increasing exploration demand for lithologic reservoirs under the slope-break belt of Yuanyanggou and Qingshui sub-sags in Liaoxi sag recently. The oil-gas exploration method based on two-phase media theory is adopted to extract the energy and frequency components of seismic waves by the characteristics of analysis on time frequency of wavelet transformation. With the sample learning of spectrum characteristics of exploratory wells, the paper summarizes the spectrum features of high-yield and oil-free wells, predicts the oil-gas enrichment degree in exploration risk areas, combined with geophysical inversion technique, and then defines the potential areas for further exploration of lithologic traps to reduce risk. |
