| 摘 要： | 大杨树盆地岩性复杂,储层含有大量孔隙及裂缝,但是在该区油气并没有取得重大突破,因此勘探方向成为研究区的重要问题。这里利用杨参1井测井数据计算了含气层位的阻抗,分析判断该含气层位AVO异常为第一类AVO异常。运用AVO分析软件处理杨参1井所在74号线的叠前道集资料,发现该含气层位AVO异常振幅为第一类AVO异常。运用AVO技术分析认为,杨参1井两侧存在范围较大的含气异常,而且存在含气性更好的第二类AVO异常特征。最后综合各类资料,认为74号线位于大杨树盆地南部坳陷最有利的勘探远景区,AVO异常特征段为下一步重点工作的地区,作为探井位置CDP3010附近应引起重视。

| Abstract: | The lithology was complex in Dayangshu basin, the reservoir contained large amounts of pores and cracks, but there wasn't a major breakthrough in oil and gas exploration in the area, so exploration was an important issue in the area. In this paper, Yangcanl well log data were used to calculate the impendence of gas-bearing layer, AVO anomaly of gas-beating layer was belong to the first AVO anomaly after analysis. AVO analysis software was used to process the prestack gathers data of line 74, where is the lo... |
