迁移型河道砂体全三维智能识别方法应用

Application of full 3D intelligent identification method for migratory channel sandbodies

河流相储层空间变化快,河道砂体存在叠置现象,导致地震上大量出现同相轴分叉、串层现象。在沉积规律认识指导下,采用立体解释技术刻画河道砂体迁移情况,从三维角度分析判识砂体空间叠置现象,该技术以三维可视化解释和河道砂体切片分析为核心,有效解决了实际工作中可能存在的解释陷阱。

There are several event bifurcations and earthquake streaks as a result of the channel sandbodies being superimposed and the fluvial facies reservoirs changing rapidly in space.The migration of channel sandbodies was described using 3D interpretation technology,and the spatial superposition phenomena of sandbodies were examined and assessed from a 3D perspective under the supervision of knowledge of sedimentary laws.The technique is focused on channel sandbody slice analysis and 3D visualization interpretation,which successfully addresses potential interpretation difficulties in practical work.
