低孔隙度低渗透率储层弯曲波影响因素分析及渗透率反演
Influence Factors Analysis of Flexural Wave and Permeability Inversion in Low Porosity and Low Permeability Reservoir
摘要
Abstract
The effectiveness of low porosity and low permeability reservoir is influenced by many factors.Based on numerical simulation, the center frequency variation of flexural wave with different permeabilities is calculated, and the feasibility of permeability inversion using flexural wave frequency shift is analyzed.Furthermore, a new permeability inversion algorithm using flexural wave frequency shift by least square method is established, and is also applied to actual well logging data processing.The result shows that the permeability inverted by flexural wave frequency shift is consistent with that measured by core test and processed by NMR well logging data, and indicates fractures well.关键词
