川西DY地区须家河组致密砂岩储层预测技术及应用效果分析
|
摘要
以储层标定为基础、储层波形特征分析为核心、地震反演处理与解释为主要手段、多种技术联合应用的储层综合预测方法。运用此技术查明了川西DY地区主力储层须家河组二段、须家河组三段的砂体具有厚度大、含气性较好、横向上分布稳定的展布格局,总结了须家河组二段、须家河组三段储层的有利反射波形特征为低频弱振幅,提出了勘探、开发部署地震选点模式及一批勘探、开发评价井位,经实钻证实预测成果可靠,钻探效果十分明显。
This paper presents an integrated reservoir prediction method which takes reservoir calibration as its basis,wave character analysis as its core and seismic inversion processing and interpretation as its major tools and joint application of various technologies as its feature.Its application in the study area reveals that the sand- stones in the second and the third members of the Xujiahe Formation have great thickness,favorable gas-bearing properties and stable lateral distribution.According to the study results,low frequency and weak amplitude are considered favorable seismic reflectance signatures of the reservoirs in the two members of the Xujiahe Forma- tion.A model for seismic-based placement of exploration and development well is put forward and several ap- praisal well locations for exploration and exploitation are proposed.Drilling results prove that the predictions are quite reliable and trustworthy.
