测井资料预处理对井约束反演影响分析及应用

储层反演技术已经成为油气勘探与开发过程中研究储层横向变化的主要手段.充分利用测井资料具有较高的纵向分辨率和地震资料的横向连续性好的特点,通过地震反演技术研究储层在空间上的变化规律,指导油气藏的勘探与开发工作.由于测井资料存在着仪器类型、测量年代差异等原因,影响了地震资料在反演过程中的准确标定和反演的结果.以准噶尔盆地石南31井区白垩系储层的地震资料反演结果为例,分析测井数据预处理对地震资料储层反演的影响.

THE INFLUENCE ANALYSIS AND APPLICATION OF WELL DATA PRETREATMENT ON WELL RESTRICT INVERSION

The technology of reserves inversion has become the main method in the course of oil exploration and exploitation. Fully using the characteristic that the well log has the high resolution in vertical and the seismic data has better continuity in level to direct the oil exploration and exploitation by the technology of reservior inversion to find the rule of the reserves distributed. But in the reason of the difference of the apparatus type and the measure time, the well log data has the influence on the demarcate precision and the inversion result. In the case of inversion result in SN31 area in Junggar Basin to analysis the influence of the well data pretreatment on well restrict inversion.
