【摘要】 油气储层速度和密度与储层参数的关系对地震资料解释以及储层参数预测等具有重要的意义。利用WX地区实际测井解释数据,就声波时差、密度与孔隙度、泥质含量以及含水饱和度之间的相互关系进行了多元线性回归分析。结果表明,用密度参数可以获得较为理想的线性回归方程,而用声波时差参数难以获得合理的回归方程。这说明密度与各储层参数之间具有较好的线性关系,而声波时差或速度与储层参数之间的相互关系要复杂得多。更多还原

【Abstract】 The relations of velocity and density with reservoir parameters are crucial to seismic data interpretation and reservoir parameters prediction. Relations of sonic interval transit time and density with porosity, clay content and water saturation are studied by multivariate regression analysis using acoustic logging interpretation data in WX area Better linear regression equations are achieved for density, but for sonic interval transit time it is difficult to get reasonable linear regression equations. It shows that density has a better linear relation with different reservoir parameters, but the relation of sonic interval transit time or velocity with reservoir parameters is very complicated.更多还原
