测井技术在地震目标追踪应用中的方法探讨
|
摘要
目前常见测井-地震综合应用技术主要是测井约束地震反演技术,该技术存在两方面的研究精度问题.一是初始模型等因素影响反演的精度和分辨率,二是波阻抗的多解性难免造成反演的多解性.由于存在以上原因,有必要探索其他方式的"井震结合"研究思路,根据测井、地震信息具有地质背景成因一致的特点,提出寻找二者具有的、可相互辨识的共同地质属性的分析方法,研究认为,测井、地震共同地质属性的辨识可表现在两方面,一是测井、地震信息在地质界面上下地质成因相同.深入研究两者可相互辨识的地质属性信息,可提供地质界面的识别与追踪依据;二是对于一个具体的地质事件或地质体,也理应找到具有同一成因基础的、可相互辨识的信息响应依据.利用该方法对羊二庄某区的实践表明,在测井、地震信息成因一致性分析手段的基础上,开展测井-地质共同地质属性的辨识、追踪研究,对复杂油气区有利目标的追踪具有有效性,该研究成果被钻井结果证实.
Currently,as the most commonly used technology in logging-seismic integrated application,the logging constrained seismic inversion technology still exists two research accuracy problems.Firstly,the initial model will affect the accuracy and resolution of inversion.Secondly,the multiple solutions of wave impedance will inevitably cause the ambiguity of inversion as well.Therefore it is necessary to explore new methods in the logging-seismic integration research.Base on the characteristics of logging and seismic having consistent geological background when they are measuring the same geologic body,proposed the analysis method of searching the geological characteristics that both logging and seismic have and can mutual recognize.Research showed that the geological characteristics recognition lies in two aspects: First,logging and seismic have the same causes on upper and lower geological interface.Geological events variation on upper and lower geological interface will inevitably lead to the change of geophysical information records.Logging and seismic have consistent causes,although they are recorded in different ways,variational structures are corresponding.Studying the mutual recognition geological attribute information between the two in depth,can provide identification and tracking basis of geological interface.Second,as to a specific geological event or geologic itself well logging and seismic information also exists the corresponding relationship on measuring,it is supposed to find an information response basis that has the same causes and can mutual recognize.The practice that utilize this method in Yangerzhuang area has shown that,based on the research method that utilize logging and seismic's consistent causes,it's very effective to explore the recognition and tracking research on logging and seismic consistent geological characteristics on the target tracking in complicated oil and gas areas,the study finding has been confirmed by drilling results.
