致密储层缝洞发育带综合预测

给出了利用不同尺度的多源信息进行致密储层发育带综合预测的方法技术系统，这种系统具有多源结构、多种层次、整体性很强的用于复杂缝洞发育带综合预测的技术流程。不同尺度间信息的沟通连接和综合利用，是缝洞预测的技术关键。详细介绍了地震缝洞检测级别标定的具体方法，提出缝洞发育级别密度的概念。把测井解释的储层缝洞发育级别转换为级别密度，可增强井、地震裂缝发育信息的贴近度。介绍了地震缝洞检测信息宏观地质规律信息相关分析的具体方法。GQ地区的应用实例证明，利用这种技术系统进行致密储层缝洞发育有利区带综合预测，能取得良好效果。

Comprehensive prediction of naturally fratured tight reservoirs

This paper discusses techniques for delineation of fracture cave zones in tight reservoirs with multi scale information of diverse sources. A workflow, which is of diverse sources and hierarchy,was proposed for prediction of complex fracture cave zones. The author suggests that the key to the prediction of fracture cave zones should be the comprehensive utilization of diverse multi scale information. The method for calibration of grades of seismic fractures and caves were discussed in detailed.Fracture rich level(FRL),a concept used for describing the growth of fractures and caves,was defined.The level of fracture abundance interpreted from logging data was changed into FRL to calibrate the information of fracture abundance in well and seismic data. Methods to correlate seismic information of fractures and caves with macro geologic information were introduced. Satisfactory results have been achieved by applying the methods and workflow to the prediction of favorable fracture cave zones of tight reservoirs in GQ survey area.
