曲线重构技术在泌阳凹陷M区储层预测中的应用
|
摘要
当储层与围岩波阻抗差异不明显或储层较薄时,利用常规波阻抗反演往往难以达到储层预测的效果。针对这一问题,通过结合泌阳凹陷M区块实际地质特点,根据区内三维地震资料、测井资料及钻井资料等,利用自然电位曲线和自然伽玛曲线,重构对储层反映敏感的泥质含量曲线。利用泥质含量曲线进行测井约束地震波阻抗反演,有效提高了反演剖面的分辨率,增强了储层砂体预测的准确性。经实际钻井及测井资料证明,该技术在研究区储层预测中取得了良好的效果。
When the reservoir and surrounding rock wave impedance difference is not apparent or the reservoir is thin,the method of conventional wave impedance inversion is often difficult to predict the reservoir.Aiming at solving this problem,combining with the practical geologic characteristics of Biyang sag,the 3D seismic information and log information with the drilling data in the area,the shaliness curve is rebuilt which can reflect the reservoir sensitively by the SP curves and gamma ray curves,then using the shaliness curves do the well constrained seismic inversion.It enhances the resolution of the inversion profile effectively,and improves the accuracy of the reservoir sand predication.The actual drilling and logging information demonstrate that the technology obtained a good result in the region in this reservoir prediction.
