摘要

松辽盆地汪家屯地区营城组火成岩极为发育,在综合分析营城组火成岩的地质、测井、地震资料的基础上,通过汪深101井基于井资料的AVO正演模型研究和叠前地震资料及相关AVO属性参数的交会分析,揭示该区火成岩含气储层的地震反射振幅随偏移距的增大而负向加大的变化规律,以及第Ⅲ类AVO异常响应特征。最后通过这些来识别岩性及预测油气。
Igneous rocks developed well in the Yingcheng Formation in Wangjiatun area of Songliao Basin.Based on the comprehensive analysis of the geological data,the logging data,and the seismic data of the igneous rocks in the Yingcheng Formation,through the study on AVO forward modeling which is based on the data of the Wangshen 101 well and the cross analysis of the pre-stack seismic data and their corresponding AVO attribute parameters,the changing law of gas bearing igneous reservoirs that the seismic reflection amplitude increases negatively along with the increment of the offset distance,and the AVO abnormal response features of the third type are revealed.Finally the lithology can identified,as well as the oil and gas can be predicted.
