以胜利油区垦西71块密井网区为例,针对复杂地层中地层对比的难题,在广泛结合前人研究基础上,提出一套运用多尺度地球物理资料进而达到精细地层对比的综合方法。该方法综合运用了测井资料纵向上的高分辨率优势和地震资料横向上的优势,考虑沉积环境对地层的控制因素对地层进行精细对比,多种资料相互配合、相互验证,有效避免穿时等问题。建立了精细等时地层格架,为下一步挖潜剩余油奠定了基础,同时对下一步油田开发方案调整具有重要的指导意义。
Taking the tight well network area of 71 West Kenland, Shengli Oilfield as an example, aiming at the difficulty of stratigraphic comparison in complex strata, a comprehensive method of applying multi-scale geophysical data to achieve fine stratigraphic correlation was proposed based on the extensive combination of previous studies . The method comprehensively utilizes the advantages of high resolution in vertical direction of logging data and lateral advantages of seismic data. By considering the sedimentary environment, the stratigraphy is controlled by the controlling factors of stratigraphy. Many kinds of data cooperate with each other to validate each other effectively. And other issues. The establishment of a fine isochronous stratigraphic framework has laid the foundation for the next step to tap the remaining oil and has important guiding significance for the next oilfield development plan adjustment.
