裂隙是碳酸盐岩的重要储层同时裂隙的溶蚀扩容是碳酸盐岩岩溶储层形成的重要因素,对裂缝性质的研究是对碳酸盐岩岩溶发育规律进行深入认识的重要途径,目前检测裂隙方法对野外采集因素要求高,裂隙检测的精确性难以保障。本文在研究区测井资料及岩心资料、试油试采资料分析的基础上,将井分类明确该地区单井裂缝发育状况,并基于此建立裂缝模型,通过裂缝预测岩石物理影响因素分析、正演记录属性分析,明确对裂缝尺度预测敏感属性,从而为后续实际资料进行多尺度裂缝预测分析奠定基础。
Fissures are important carbonate reservoirs and erosion and expansion of fractures are important factors in the formation of carbonate karst reservoirs. The study on the nature of fractures is an important way to make a deep understanding of the law of carbonate karst development. At present, The method of detecting fissures has high requirements for field acquisition, and the accuracy of fissure detection is hard to guarantee. Based on the analysis of logging data, core data and test-oil production data in the study area, the paper classifies the wells as clear as the development status of single-well fractures in this area and establishes the fracture model based on this. Through the analysis of the influence factors of rock physics in fracture prediction, It is helpful to predict the sensitive properties of the fracture scale in order to lay the foundation for multi-scale fracture prediction analysis of subsequent actual data.
