摘要
由于碳酸盐岩储集空间复杂多样,利用单一的参数或方法存在多解性且易受区域地质条件的限制。基于这一考虑,提出了基于置信度分析的多方法综合进行裂缝的检测。该方法利用测井的裂缝解释结果与各方法检测结果的相关性对不同的检测方法检测结果加权,从而提高了检测的可靠性。另外,该方法可适用于不同地区,避免了不同地区的地质条件对单一检测方法的限制。该方法应用于塔河地区,收到了良好效果。
Complexity of carbonate reservoir pore space allows single parameter or method to give non-uniqueness of solutions and be likely limited, by regional geologic conditions. For this reason, this paper presents a method for confidence analysis-based integrate fracture detection. The method makes use of correlation between well log fracture interpretation and other fracture detection results to weight all results from different detecting methods in order to improve the detection reliabilities. The method can be used in different areas like Tahe oilfield without any restriction from complicated geologic eonditions. The case study shows better effectiveness than befure.
