铜锣峡构造中南段飞仙关组储层主要发育在飞一段和飞三段的鲕粒灰岩中,储层具有明显的低孔低渗特征,属裂缝型储层。过去多采用单一方法来预测裂缝型储层,如常用的地震速度反演等,但预测效果往往较差。本研究采用曲率法及STRATA反演来综合预测裂缝型储层,预测精度明显提高;主要是对传统的曲率法进行了重大改进,在各网格节点上分别计算了线曲率及面曲率,经标准化处理后,再提取各节点上的曲率最大值来预测构造裂缝发育区。

The reservoir mainly developed in the T_1f~1 and T_1f~3 oolite limestones, which was unambiguously characteristic of low porosity and flow permeability and belonged to fracture reservoirs. A single method was used to predict the fracture reservoirs in the past, such as the inversion of seismic velocity in common use etc, the prediction effect of which was relatively bad. This study combined curvature method with the inversion of STRATA for predicting the fracture reservoirs, the precision level .
