鄂尔多斯盆地塔巴庙工区下石盒子组砂岩储层综合预测技术

鄂尔多斯盆地塔巴庙工区下石盒子组砂岩体主要属平原分流河道沉积，具有低孔、低渗和高阻抗特征。针对这一地质目标，提出了以ＢＣＩ反演处理、解释技术为核心，以ＡＶＯ特征响应为依据，以时频主参数为参考，综合地质、测井、地震多学科的储层预测技术系列，指出了有利的储集区。

Integrated prediction techniques for sand reservoirs at lower Shihezi formation of Tabamiao area in Erdos Basin

The sand body at Shihezi formation of Tabamiao area in Erdos basin is mainly plain and fluvial deposits with characteristics of low porosity, low permeability and high impedance. In compliance with such a geologic understanding, a series of reservoir predication techniques, among which BCI inversion and interpretation is the kernel, have been proposed by combining with geology, logging and seismics. The multidisciplinary methods, which base on AVO responses and use time frequency parameters as references, have pointed out some favorable reservoir areas.
