摘要
塔河油田A区石炭系卡拉沙依组是重要储油层系之一,而储层的空间展布,厚度变化及物性特征的落实程度是勘探开发的关键问题。针对这些难点,在精细岩石物理特征分析的基础上,研究了目标特征曲线的构建方法,利用分频反演方法,得到高分辨率的反演数据体,追踪解释有利砂体,建立了一套行之有效的适合该区石炭系储层预测工作的技术流程,取得了良好的应用效果。
The Carboniferous Kalashayi Formation of Block A in the Tahe oilfield is one of the most important oil-bearing formations in the area. A thorough understanding of its spatial distribution, thickness and physical pro-perties is crucial to exploration and production. To tackle the problem, the researchers study the construction of target characteristic curves based on a fine analysis of petrophysical features and obtain a high-resolution inversion data volume for prediction of favorable sand bodies by adopting frequency-divided inversion method. As a result, an effective technical process is established for the prediction of the Carboniferous reservoirs in the area and its application has been proven successful.
