【摘要】 针对目前胜利油区浅层气藏预测亮点技术存在的多解性和假亮点等问题,以陈家庄凸起陈气12井区为研究对象,进行浅层气藏预测识别技术研究。在进行叠后地震相关处理的基础上,结合地质、地震和测井资料,首先利用相干体分析技术和属性提取分析技术进行河道砂体检测,然后综合利用瞬时子波能量吸收技术和属性提取分析技术对检测出的河道砂体进行含气性检测,识别出水层引起的假亮点。陈气12井区的含气性检测结果与实钻井情况吻合良好。更多还原

【Abstract】 In view of the problem of the technology to forecast bright spots in shallow gas reservoirs in Sbengli Oilfield,prediction and iden- tification techniques were researched in Chenqi12 wellblock. Based on the post-stack seismic processing,channel saM bodies were detected by coherenee and attribute extraction analysis,then techniques of transient wavelet absorption and the attribute ex- traction analysis were used to verify gas-containing probability in the detected sand bodies,and the false bright spots caused by water layers was identified combined with geology,seismic and electrofacies.The detected results of the gas-containing probabil- ity accorded with the facts well.更多还原
