| 摘 要： | 本文通过对测井、地质等资料的分析,选择分布稳定、岩性单一的地层作为标准化处理的标准地层.通过对声波曲线进行误差校正和重构,使储层的速度和波阻抗特征更加明显,以此来区分砂岩与泥岩,提高识别储层的精确度.同时,通过对测井资料的统计分析使反演剖面的横向变化比较均衡,而且与地下地层岩性的实际变化更加吻合,解决了井间能量分布不均匀这一问题.

| Abstract: | This paper analyses the oil well logging and geology information and chooses stratum with distributional stability and unitary crag character as standard stratum.In order to discriminate sandstone and putty and enhance the precision of reservoir recognition,the paper carries on error correction and reconstruction to the sound wave curve to make the reservoir speed and wave impedance character more obvious.Then the paper statistics and analyzes the log information to make the inversion section plane's crosswise changes even and tallies with actual changes of subsurface formation's crag,which solves the problem of energy distribution non-uniformity between well. |
