摘要
在常规测井数据标准化处理中,单井误差消除和多井一致性校正都是从测井角度进行的,当面对复杂的陆相沉积地层时,地层单元在井间很难进行等时及准确的对比解释,标准化后的测井资料质量仍然不能满足基于测井的储层地质特征精确描述与刻画的高要求。为此,提出了一种井震结合测井资料标准化新思路,并在标准化处理各步骤中更多地融入地震信息,即在地震相对等时间地层沉积格架宏观约束下,强调把测井垂向高分辨性与地震空间上连续性紧密结合起来,从整体上进一步提高测井资料标准化效果与测井分析数据的质量,为后续更合理、更准确地开展储层精细描述阶段的测井数据储层地质解释、储层参数定量计算和三维储层静态地质建模打下良好基础。
In the traditional logging normalization,error elimination for single well and consistency correction for multiple wells are only based on logging data.For complex continental sedimentary reservoirs,it is difficult to carry out isochronous and accurate crosswell correlation and interpretation on stratigraphic units.Moreover,the logging data after normalization still cannot satisfy the requirements for fine characterization of the reservoir geologic features.Therefore,we proposed a well-to-seismic logging data normalization workflow,and introduced more seismic information into every step of normalization.Restrained by the macro sedimentary framework of seismic relative isochronous stratigraphy,the method focus on combining the vertical high-resolution of logging data with spatial continuity of seismic data,which makes holistic improvement for log normalization and data analysis.Meanwhile,it provides good basis for the more reasonable and accurate geologic interpretation,parameter quantitative computation and 3D static geologic modeling of reservois.
