Abstract
The factors affecting the extraction of P-wave and S-wave from through-casing array acoustic logging data are analyzed.The interval travel time of P-wave is affected by casing size, cement ring cementation,borehole enlargement and formation properties.Cementing quality is the main influencing factors.In the case of better cementing quality,the extracted P-wave by array acoustic logging needn't to be corrected;For the bad cementing quality,the extracted P-wave by array acoustic logging can not reflect the P-wave information of actual formation,so it is necessary to make correction.By using shear wave inversion,a reconstruction method of compressional wave slowness is presented, regression equations of P-wave slowness reconstruction are established in five blocks,Ordos Basin.The verification and analysis of acoustic logging data of 34 wells shows the method is feasibility and practicability.关键词
