| 摘 要： | 提取叠前地震振幅信息的叠前反演技术已成为储层预测的重要手段,其能获得各种岩石弹性参数,丰富储层预测方法.因目标储层的差异性,优选并建立有利的流体敏感参数对储层流体检测尤为重要.本文基于岩石物理实验, 测量并分析了岩石弹性参数随流体饱和度的变化特征, 进一步根据岩石物理理论建立组合流体敏感参数, 达到对油气检测的最佳敏感效果.定义了流体敏感量,定量分析岩石弹性参数的流体敏感性.最后本文在X区块进行了叠前地震反演的应用, 结果表明通过岩石物理实验分析并建立获得的流体敏感参数能明显的提高储层的识别能力.

| Abstract: | The pre-stack inversion has become an important means of reservoir prediction,and it can get all kinds of rock elastic parameters,which enriched the reservoir prediction methods.Because of the difference of the target reservoirs,to select and establish good reservoirs sensitive parameters for reservoir prediction is particularly important.This paper,based on the rock physics experiment,measures and analyzes rock elastic parameters characteristics with the change of fluid saturation,farther more,according to rock physics theory,to establish combined fluid sensitive parameters,for getting the best effect of oil and gas detection.And it defines a fluid sensitive factor to quantitatively analyze fluid sensitivity of rock elastic parameters.At last,this paper makes pre-stack seismic inversion in an actual area,and the result shows that the fluid sensitive parameters obtained by the rock physics experiment analysis can obviously improve reservoir identification ability. |
