为了使测井资料更能客观反映研究区储层“四性”关系和保证精细油藏描述的可靠性,本文选取声波时差较稳定、自然伽马中、低值的长62这一套稳定致密的砂岩作为标志层。由于本地区测井资料较少,只选取研究区的声波时差曲线,采用频率直方图法和趋势面分析法从定性分析和定量计算两方面对其进行标准化。研究表明,标准化后效果较好,符合实际地质特征,为研究区后续“四性”关系研究和油藏精细描述奠定了坚实基础。
In order to make the logging data more objectively reflect the reservoir “four sex ” relationship and ensure the reliability of the fine reservoir description in the study area, this paper chooses a set of 62 Stable and dense sandstone as a marker layer. Due to the small number of well logging data in the region, only the acoustic time-difference curve of the study area is selected, and the frequency histogram method and the trend surface analysis method are used to standardize the analysis from qualitative analysis and quantitative calculation. The research shows that the standardization is effective and in line with the actual geological characteristics, which lays a solid foundation for the study of the follow-up relations and the detailed description of reservoirs in the study area.
