地震反演技术在储层预测中的应用--以辽河滩海东部凹陷东营组为例

摘要

地震反演技术是储层预测的主要手段。辽河滩海东部凹陷勘探程度低，成果少。综合运用地震、测井、钻井等地质资料，通过建立绝对波阻抗模型，约束稀疏脉冲反演技术较好地预测了研究区内东营组各层段的储层发育有利区带。结合前期地质资料，认为研究区内葵花9井区、太阳3井区、龙王井区以及海12井处的三角洲砂体为主要的储层发育有利区带。%Seismic inversion technology is the main means for reservoir prediction. The east sag of Liaohe beach area has low de-gree exploration and scarce results. Based on the seismic, well logging and drilling data, constrained sparse pulse inversion has bet-ter effects on the predication of the favorable reservoir zone of Dongying Formation with the establishment of the data volume of ab-solute wave impedance. On the basis of preliminary geological data, research inferred that delta sand body in Kuihua 9 well block, Taiyang 3 well block, Longwang well block and Hai 12 well block are favorable reservoir zones.
