| 摘 要： | 利用分频解释原理沿着目的储层或固定时窗对地震反射成分中各种频率成分对应的调谐能量进行识别成像,并以此解释技术来识别砂体的空间展布形态、相对沉积厚度及薄互层叠置关系。某地区目的层—沙溪庙组以一套河流-三角洲沉积为主,且薄互层发育,单层厚度多在20 m以下,基于传统地震属性分析(振幅、相位等)的有效分辨率、检测极限的限制,为了能更精细刻画砂体边界和寻找相对有利储集相带,首次将分频解释技术加以运用,分析成像结果显示古河道、水下分流河道、三角洲前缘席状砂体等外形和边界异常清晰,相对沉积厚度关系明确,十米左右的薄层砂体均能得到很好的响应,与已知钻井情况吻合率达95%以上。

| Abstract: | Interpretation principle of frequency division is used to identify the syntony energy corresponding to the seismic reflection along certain reservoir and fixed time-window,and determine the spatial distribution shape,sedimentary thickness and relative thickness of the reservoir beds.The a certain strata,which is characterized by river to delta sedimentation with thin alternation layers less than 20 meters,is taken as a target beds for the research.The traditional analysis of seismic property is restricted by effective resolution and detecting limit.So the interpretation of frequency division is,for the first time,used to precisely delineate the boundary of sand bodies and look for the favorable reservoir facies.It is showed that the final result of analysis images is very clear in demonstrating the shape and boundary of the ancient river courses,sheet-shape sand bodies in the front of delta and the thickness of the beds,even those beds with their thickness less than 10 meters.The precision of this technique is high and can reaches 95%. |
