地层切片技术在识别X区块U层段有利沉积微相中的应用
|
摘要
由于地层切片相比时间切片、沿层切片更接近等时界面,更具有等时沉积意义,因此能更真实地反映储层沉积特征.X区块U层段为辫状河平原沉积,沉积微相类型主要包括辫状分支河道、泛滥平原等.分支河道微相往往沉积交互叠置厚层砂岩储层,形成有利的储集体.基于人工三维地震资料,利用地层切片技术对U层段沉积微相进行了识别和分析,指出了有利的沉积区域,为后续的井位部置提供依据.
Comparing with the time slice and horizon slice,the strata slice is more practical and meaningful in sedimentary way since it is much closer to the interfaces at the same period,so that it has been used popularly in interpreting the geological meaning for target formation.In X area,braided plain is the dominant facies for U formation and the sub-facies including braided channel and flood plain.The channel is the source of reservoir,and the sand body is always thick and cross-bedded.On the basis of the three-dimension seismic attribute data,distribution of the sedimentary facies has been studied using the strata slicing technique,and the favorable area has been pointed out,which can be the basic technical support for the later research and well plans.
