储层含油气预测是松辽盆地北部杏西地区葡萄花油层岩性油气藏勘探的难点.在岩石物理分析的基础上,以多属性交会分析为手段,以理论和正演结论为指导,利用AVO反演技术进行岩性和流体预测.研究认为：葡Ⅰ2油层段储层含油气之后其AVO特征为Ⅰ类AVO异常,MuRo反射率属性能够较好地反映岩性的变化,而流体因子反射率属性能够较好地反映流体的变化;利用这两种AVO属性的分析结果,可得到杏西地区葡萄花油层储层含油气性分布,为储层预测和含油气判别提供了有利依据,在实际生产中取得了较好的应用效果.

英文摘要：

Petroleum-bearing prediction for Putaohua reservoirs in Xingxi area of North Songliao Basin is the diffi- culty for the lithologic hydrocarbon exploration. On the basis of rock physical analysis, by means of multi-attribute crosslink analysis and guided by the theory and forward modeling inclusion, the lithologic and liquid predictions are conducted with the help of AVO inverting technique. The researches show that Type I AVO abnormity in Pu I2 oil interval is indicated after it is enriched with the hydrocarbon, MuRo reflectivity attribute can better reflect the li- thological change, while the reflectivity attribute of the fluid factor can obviously show the change of the fluids ; with the help of the above analyzed results of two AVO attributes, the petroleum-bearing distribution for Putaohua oil reservoirs in Xingxi area can be clarified, thus the favorable evidences are presented for the reservoir prediction and petroleum-beating detection and moreover much better applied results are achieved in the practical operation.
