应用自然伽玛测井曲线小波分析划分陆相坳陷盆地三级层序的方法:以鄂尔多斯盆地延长组为例
|
摘要
以鄂尔多斯盆地延长组为例,选择10口油气探井为研究样本,利用自然伽玛测井曲线小波变换的2个地质属性,采用小波周期与区域标志层、地震层序和综合层序划分结果比对法,确定了GR-Dm ey-D 10小波可以作为鄂尔多斯盆地延长组三级层序的参照性量化标准。实际应用效果证明,自然伽玛测井曲线的小波分析法可以协助我们统一层序划分方案,提高层序划分精度,恢复被剥蚀层序厚度,提高层序地层工业化应用研究及工业化制图程度,适用于大部分稳定陆相坳陷湖盆三级层序划分。
The thesis take the Yanchang team of Ordos basin as the example,select ten drilling as study sample,use the two attribute of the wavelet transform of gamma ray logging,adopt the correlation method such as wavelet period,range marker horizon,earthquake succession of strata and the outcome of synthesis succession of strata division,the conclusion show that GR-Dmey-D10 wavelet can be used as a quantization criterion to demark the third-degree succession of strata.The application effictiveness show that the wavelet analysis of gamma ray logging can help us to unify the project of succession of strata division,to upraise the accuracy of succession of strata division,to recover the thickness of denudation succession of strata division,to upraise the degree of the study of succession of strata and the industrialization mapping.The method is available in the area of the division of third-degree succession of strata in most part of stationary continental facies depression lake basin.
