【摘要】 通过实测资料、盆地模拟、声波测井和地震速度计算,精细刻画了断陷湖盆深部流体超压特征。对东营凹陷和东濮凹陷的勘探实例研究表明:泥岩层与砂岩储层的压力分布特征存在一定差异,由于烃源岩层生烃传递作用而导致储层形成超压;深部压力系统演化呈现多期旋回性,晚期油气充注以超压背景为主;超压控制着油气形成与分布。更多还原

【Abstract】 The characteristics of abnormal fluid pressure in the deep area of faulted basin were depicted through tested data and basin simulation,sonic logging and calculation of seismic velocity.Case study of Dongying and Dongpu Depressions indicates that the distribution of abnormal pressure in mudstone and sandstone has certain difference.The overpressure system is induced by the transfer of hydrocarbon genesis in the reservoir,the evolution of deep pressure system is in multi-stage cyclics,the charging of late oil and gas is in the overpressured background and overpressure controls the formation of oil and gas and their distribution.更多还原
