在埃及近海的尼罗河三角洲预测砂体分布和储层的存在具有较大的勘探风险。然而,综合多种现代技术,包括三维勘探、地震属性、振幅提取和相干体技术来识别并更精确地使水下河谷和河道复合体成像,可以减小这种风险。此外,识别沉积物的输入点和通道可以更精确地解释砂体的分布特征。从有利区域的地震剖面显示出中新统上部(Messinian)蒸发岩产生了一系列亮点反射,它们被上新统下部的海进层序所覆盖,基于钻井资料和地震特征,这套海进层序似乎是相对富砂的地层。偏页岩的上新统中部比较模糊,具有弱的不连续反射及一些明显的侵蚀面。上新统上部和更新统层段复杂,具有丰富的侵蚀面和滑塌面。在地震上它们是较亮的反射.井标定为砂岩。
Predicting the distribution of sand bodies and the presence of reservoirs in the Nile Delta off the coast of Egypt have a greater exploration risk. However, the combination of multiple modern technologies, including 3D prospecting, seismic attributes, amplitude extraction, and coherent techniques, to identify and more accurately image underwater river and river complexes can reduce this risk. In addition, identifying the sediment input points and channels can more accurately explain the distribution of sand bodies. Seismic profiling of the favorable area shows a series of bright-spot reflections from the Miocene Messinian evaporites that are covered by marine sequences beneath the Lower Pleistocene. Based on drilling data and seismic characteristics, this marine formation Order seems to be relatively rich sand formation. The middle shaliks of the shale are rather vague and have weak discontinuous reflections and some obvious erosion surfaces. The Upper Pleistocene and Pleistocene intervals are complex with rich erosion and slump surfaces. They are brighter reflections on earthquakes, and well-marked sandstones.
