岩石物理建模技术在致密砂岩储层预测中的应用——以鄂尔多斯盆地北部H区块为例
Application ofrock physics modeling in the prediction of tight sandstone reservoir ——A case study of H block, Northern Erdos basin
摘要
Abstract
Construction of rock physics model is a significant and fundamental work in pre-stack inversion. In this paper, aiming at tight sandstone reservoir, we analyzed the main procedure of rock physics modeling. It is noteworthy that we combined well logging analysis and rock physics modeling as an iterative process, since logging data analysis is able to provide massive basic data to modeling while modeling is capable of controlling the quality of logging evaluation parameters. As we obtained high quality well logging data, the most sensitive parameters and optimal procedure of rock physics modeling has been selected, which help us to precisely predict the shear wave velocity and other reliable data for pre-stack inversion. Meanwhile, rock physics templates have been built up to interpret the inverted elastic velocity volume. This can improve the precision of identification for tight sandy reservoir. Finally, good results have been achieved in Erdos basin based on our raised method.关键词
