摘要
研究区位于川东南地区飞仙关组、嘉陵江组和须家河组,对已有的AVO采集资料处理研究表明,研究区AVO特征并不明显。根据已知测井资料及野外采集参数,应用R.T.Shuey近似公式,有针对性地建立了研究区含气和非含气条件下的AVO特征曲线及二维模型模拟,提取了AVO属性参数。对在川东南地区飞仙关组、嘉陵江组和须家河组应用AVO进行油气预测的可行性进行了分析和总结,提出了在研究区应用AVO进行气藏检测的依据和方法。
The interest targets include Feixianguan formation,Jialingjiang formation and Xujiahe formation in the southeast margin of Sichuan Basin.The collected AVO data which has been processed and researched shown that the AVO feature was not clear in this area.On the basis of known logging data and the parameters collected in the field,the area of AVO curves and two-dimensional model were established by use of the R.T.Shuey approximate formula in the conditions of gas and non-gas.The AVO property parameters were extracted and the feasibility of application of AVO for oil and gas forecast prediction in the southeast margin of Sichuan basin were analyzed and summarize.The basis and method of application of AVO for gas reservoir detection were proposed.
