松辽盆地南部M地区泉一段重构反演预测研究

The Research on Inversion Prediction Reconstruction of Member 1 of Quan Group in M Area in Southern of Songliao Basin

摘要: 针对M地区泉一段储层预测难的特点，本文采用曲线重构反演方法，通过测井曲线资料预处理、地震资料预处理、子波提取与合成记录质控、地质模型估算等重要环节的实现，从而完成了M地区泉一段储层预测工作。重构后反演效果较好，较好地刻画了泉一段砂体的空间展布，洼槽带厚砂体呈片状分布，背斜带和斜坡带砂体呈小片状为主，局部砂体呈甜点状为主。

Abstract: Due to the hardship of Reservoir Prediction of Quan-1 Member in M Area, the method of curve rebuilding inversion is adopted in this paper. Reservoir Prediction is accomplished through a number of processes, such as well log data pretreatment, seismic data processing, wavelet calibration and control, geologic model and so on. The result proved to be reasonable, and the spatial morphology of sand bodies of Quan-1 Member is well illustrated. The sand layers are thick and distribute continually in the trough belts, and less distributed in anticline zones and slope belts, while existed as sweet spots in some local areas.
