摘要
高分辨率层序地层学克服了岩性地层对比穿时的缺点。高分辨率层序地层对比是等时的高精度的地层对比,它满足了勘探开发中地层对比等时性和高分辨率的要求。测井资料的纵向分辨率较高,是高分辨率层序地层研究的重要资料。提出了利用测井相分析技术,从测井资料上识别出单井岩性和沉积微相剖面,结合测井曲线特征,划分单井基准面旋回,并进行连井地层等时对比,这为定量地进行高分辨率层序地层分析提供了一种方法。通过研究区实际资料的处理,验证了该方法的有效性。
High-resolution sequence stratigraphy overcomes the fault of diachroneity in lithostratigraphic correlation. High-resolution sequence stratigraphic correlation is isochronous, it satisfies the requirements of isochronism and high-resolution of stratigraphic correlation in petroleum exploration and development. Logging data plays an important role in high-resolution sequence stratigraphic research since its rather good vertical resolution. Log facies analysis method starting with logging data to identify lithology and sedimentary micro-facies profile of individual well, and method applying suitable logging series to distinguish base-level cycle of individual well, then, to make high-resolution sequence stratigrapnic correlation and isochronous correlation of multi-well base-level cycle, are described. The effectiveness of the methods was verified by the processing results of real logging data in objective regions.
