东营凹陷浊积砂体叠后地震属性与储层物性相关性研究
摘要
Abstract
The third member of the Shahejie Formation in Niuzhuang sag of Dongying Depression is typical for developing turbidite sandstone lithologic reservoirs with relatively simple structures. Take a turbidite sandstone reservoir with more than twenty wells as an example, we carried out statistical analysis on measured reservoir physical properties (sandstone thickness,porosity,permeability,etc) and post-stack seismic attributes (reflection amplitude,frequency,energy,etc) and their correlation. The results show that:①some pairs of physical properties has good correlation, such as porosity and permeability, sand-bodies thickness and sand-layer thickness, shalecontent and porosity;②the correlation between amplitude and energy is good, and dominant frequency and instantaneous frequency exist a linear relationship but the coefficient is low;③there are certain correlations between seismic attributes and the reservoir physical properties,but the correlation coefficients change greatly;④the number and distribution of samples have serious influence on statistic result. The above recognitions guided the prediction of lithologic reservoir in Yanjia-Yongan area of northern Dongying Depression. The average error of the achieved sand porosity is smaller than 7%. Meanwhile,the prediction result of physical properties of turbidite sandstone reservoir in Shinan area was remarkable.关键词
