测井—地震多属性分层重构特征曲线技术
|
摘要
为提高特征曲线的岩性识别能力及反演分辨率,本文将测井—地震多属性分层重构特征曲线技术应用于井约束反演。指出密度数据的变化对反演结果敏感;综合利用多种测井—地震属性反映岩性特征;针对不同目的层,对声波和密度曲线分别进行重构处理。应用结果表明,对声波和密度曲线进行测井—地震多属性分层重构再用于反演,可消除高阻泥岩、井壁垮塌等因素造成的声速过高、密度失真等影响,突显储层与围岩的差异,提高岩性识别能力和反演分辨率。
In order to raise lithological recognition capacity and inversion resolution for the characteristic curves,well logging-seismic multi-attribute stratified reconstruction characteristic curve technique was applied in well constraint inversion.It is pointed out in this paper that the change of density data is sensitive for inversion results.The multi well logging and seismic attributes were integratedly utilized to invert lithological characteristics,for different target zones,the reconstruction processing was conducted for sonic curves and density curves respectively.The application results showed that the sonic curves and density curves on which the well logging-seismic multi-attribute stratified reconstruction and inversion were conducted could remove some impacts,such as high sonic velocity,density distortion and so on which were caused by factors like high resistance mudstone,wellbore collapse and etc.,as a result the difference between reservoir and surrounding rocks was highlighted and lithological recognizance capacity and inversion resolution were raised.
