辽河坳陷滩海区海月潜山裂缝型储层预测研究

裂缝型储层是潜山油气藏的重要储集层，裂缝形成的控制因素复杂，识别难度大；然而裂缝形成机制和地震反射特征是有规律可循的。因此，对裂缝发育控制因素和分布规律进行了分析探讨，并采用蚂蚁追踪裂缝识别、吸收衰减属性分析和多属性聚合分析等技术对潜山储层进行预测，细化处理流程，多种预测相互印证，减少单一预测方法存在的多解性和局限性，提高了潜山储层预测的可靠性。利用该方法在辽河坳陷滩海区海月潜山裂缝型储层进行实际应用，并取得了较好的效果，为潜山勘探提供了重要依据。

Fracture-type Reservoir Prediction in Haiyue Buried Bill of Tanhai Area,Liaohe Depression

The fracture-type reservoir is one of the important types for buried hill reservoirs. Although the forming mechanism and seismic reflection characteristics of fracture-type reservoirs are complex and hard to be identified, there are still rules that can be followed; therefore this study analysis the controlling factors of fracture development and summarizes the distribution regularities of fractures. Furthermore the methods including ant tracking, frequency attenuation and multi-attribute analysis are employed to predict the buried-bill reservoir. With the above multiple prediction methods, the processing procedure can be refined and the predicting results can be referred to each other, thus the reliability of buried hill reservoir prediction is much improved, avoiding the ambiguity resulted from single processing method.Taking Haiyue buried hill of Tanhai area in Liaohe depression as an example,this study uses the above methods to predict fracture-type reservoirs of this area, and the predict result is verified by well data and is coincide with the practice, providing an important basis for exploration of buried hill reservoirs in this area.
