摘要
裂缝性变质岩潜山储集层具有形成条件复杂、储集性能控制因素多、储集层非均质性强等特点,声波时差不能满足储层预测要求,传统储层预测技术面临严重挑战。以JZ25-1S太古宇变质岩潜山为研究对象,在地质、测井、地震综合研究的基础上,针对具体地质问题和反演目标,以岩石物理学为基础,从多种测井曲线中优选并重构出能反映储层特征的拟合曲线。通过数理统计方法将该曲线转换成拟声波时差曲线,实现储层特征曲线重构。基于重构的拟声波曲线开展变质岩潜山储层三维反演预测,反演结果有效地指导了该潜山裂缝油藏的开发,开发井储层实钻吻合率达到70%以上。
Fractured metamorphic buried hill reservoir has such characteristics as complicated formation conditions,more control factors of reservoir properties,strong reservoir heterogeneity. So acoustic curve can't meet the requirements of reservoir predication,and conventional reservoir predication technology is facing severe challenges.Taking the JZ25- 1S Archaean metamorphic buried- hill oil reservoir as the object of studies,on the basis of comprehensive study in geology,well logging and seismology,for specific problems and inversion target,based on rock physics,fitted curve that can reflect the characteristics of the reservoir can be optimized,selected and rebuilt from a variety of logging curves. And then transform the fitted curve into pseudo- acoustic curve to realize the rebuilding of reservoir characteristic curve. Based on the pseudo- acoustic curve,3D inversion prediction of the metamorphic buried hill reservoir can be carried out,and the inversion results effectively guide development of the buried hill fractured reservoir. Reservoir coincidence rate of the drilled development wells reaches more than 70 percent.
