【摘要】 平湖地区砂岩气藏埋藏深度为3000~4300m,气藏在地震剖面上不具有典型的“亮点”指示现象。针对这一特殊气藏条件,利用道积分原理和AVO属性分析技术,开发了相对泊松比分析技术,找出了相对泊松比与气藏之间的特征关系,建立了中深层砂岩气藏的检测方法。通过钻井检验,预测的气层与实际钻遇情况基本吻合,从而证明了该方法具有较好的实用性。更多还原

【Abstract】 Burial depth of sandstone gas reservoirs in Pinghu area is 3 000 ~4 300m. Typical bright spot anomaly does not appear in seismic profile of the gas reservoirs. Relative poisson’s ratio analysis technique is developed based on trace integral principle and AVO attribute analysis technology according to the special condition of the gas reservoirs. The characteristic relation between relative poisson’s ratio and gas reservoirs are found and a detection method for the middle-deep sandstone gas reservoirs is established. Forecasted gas reservoirs are almost the same as the actual drilled ones. It is proved an effective method.更多还原
