摘要
在准噶尔盆地车排子地区利用振幅属性及叠前属性进行油藏预测取得了良好效果,但同时伴随着部分井失利。分析认为失利原因与属性的多解性有关,多解性产生的原因在于地质因素影响、地震资料采集及传播过程中影响、地震资料处理过程中影响、主观因素影响等几个方面。通过对这几方面影响因素的深入分析研究,并采用合理对策,提高了该区油藏预测的准确性。
The amplitude attributes and Pre-stack attributes have been applied in Chepaizi Area of Junggar Basin to predict reservoir with good results except that several wells were failed.It is regarded that the failure was partly due to multiplicity assessment of seismic attributes.There are many factors that lead to multiplicity assessment,such as geological causes,acquiring and transmission of seismic data,processing of seismic data,and subjective experience,etc.It proves to be effective to improve accuracy of reservoir prediction by analyzing these factors thoroughly and adopting reasonable countermeasures.
