摘要
利用珠江口盆地珠一坳陷珠海组取心井、测井及地震资料,探讨了珠海组三角洲沉积的岩石相、沉积微相、沉积亚相特征及发育分布规律,分析了其岩电响应特征,进而建立岩电响应模式,并通过研究区井-震对比,建立了珠海组三角洲沉积的地震响应模型。
Twelve lithofacies including the sandstone and conglomerate facies with massive bedding, sandstone facies with trough cross-bedding and sandstone facies with parallel bedding are recognized in the Zhuhai Formation on the basis of lithofacies, well logs and seismic reflection profiles of the delta deposits from the Zhuhai Formation in the Zhu-1 depression of the Zhujiangkou Basin. The delta deposits take diverse forms: composite boxes or composite funnels for well 10gs, and wedge-shaped, siglnoidal and mound for seismic reflection configurations.
