基于波形指示反演在储层预测中的研究及应用
The Research and Application of Waveform Indicating Inversion in Prediction of Reservoirs
摘要
Abstract
The accuracy of thin reservoir prediction is a difficult issue in oil and gas exploration and development. As an important technique of reservoir prediction, wave impedance inversion can effectively improve the prediction accuracy of thin reservoir. In this paper, a new inversion method based on the cooperative representation of borehole and earthquake is proposed, which can realize the inversion method of seismic wave line indication based on the waveform driven by structured inversion algorithm. In the process of inversion, through curve reconstruction, reservoir structure analysis and sample optimization, the range of inversion determinate frequency components is improved and the high frequency components are determined from stochastic to relative. The method has been used in the exploration of Bohai oilfield, and the effective distinction is made between theⅣoil group sand bodies in the lower section of Bozhong oilfield A, and the distribution range is predicted accurately.关键词
