Jason反演技术在腰英台地区营城组火山岩储层预测中的应用

Jason多井约束反演技术是目前储层预测的核心技术,它对储层在空间横向上的分布有很好的预测作用,可作为发现隐蔽油气藏的有效手段。以腰英台地区为例,在地质储层特征研究的基础上,开展了以对有效储层的敏感性分析为基础、子波提取和层位标定为保障、建立低频阻抗体模型为核心的测井约束地震反演技术研究。结果显示:反演结果准确可靠。对腰英台地区营城组储层进行厚度的预测,直观地刻画了储层的空间分布规律,确定了有利区块,为腰英台地区的储层评价和井位部署提供了重要依据。

The application of Jason Inversion Technology to predict the reservoirs in Yingcheng formation of Yaoyingtai area

Jason multi-well constrained inversion is the core technology of the reservoir prediction.It has very good prediction effect on reservoir transverse distribution in space and can be used as effective means of discovering subtle reservoirs.By taking Yaoyingtai area for example,based on the study of geological reservoir characteristics,the flow of seismic inversion includes sensitivity analysis,wavelet extraction,horizon calibration and wave impedance model building.The results show that the inversion results are accurate and reliable.Finally the thickness of Ying Cheng reservoir are predicted in Yaoyingtai area,the spatial distribution laws of the reservoir are intuitively portrayed and favorable blocks are discovered,The results provide valuable evidence for reservoir evaluation and the well deployment.
