准噶尔DX18区块裂缝性火山岩储集体三维地质建模
|
摘要
准噶尔DX18区块油藏由4个相互叠置的火山岩体组成,为孔隙-裂缝双重介质火山岩储集体。火山岩体内部的裂缝主要为构造缝,在空间上连片分布,裂缝发育部位纵、横向的连续性都较差。为了编制油藏开发方案及进一步完善开发井网,用三维地质建模方法研究了裂缝的发育及分布特征。针对火山岩体空间结构复杂的特点,首先采用体控构造建模方法描述火山岩体的整体三维空间形态;结合地震数据和测井解释结果,分析了各种地震属性与裂缝发育带的关系,在此基础上采用井震结合的震控建模方法建立了火山岩体的三维属性模型,裂缝孔隙度模型采用地震神经网络孔隙度体进行约束,裂缝密度模型采用地震倾角体进行约束。后期的钻探及开发动态数据表明,震控地质模型较准确地描述了该区块火山岩体内的主要裂缝发育区,符合率在93.8%以上。图8参22
The DX18 reservoir is composed of four mutually superimposed volcanic bodies and is a pore-fracture dual-media igneous reservoir.The fractures inside the volcanic bodies are mainly structural fractures with continuous distribution in space,and the continuity of fracture development positions is poor both vertically and horizontally.For the preparation of reservoir development scheme and further improving production well pattern,the fracture development and distribution characteristics are studied by 3D geological modeling.In view of the complexity of spatial structure of volcanic bodies,a body-controlled structure modeling is applied to describe the entire 3D shape of volcanic bodies.By integrating seismic data and logging interpretation,the relationship between various seismic attributes and fracture development zone is analyzed.Based on the analysis result above,a seismic-constrain modeling method which integrates the well data and seismic data is applied to establish the 3D property model for volcanic bodies.The fracture porosity model is constrained by seismic porosity data volume created by neural network processing,and the fracture density model is constrained by seismic dip volume.The later drilling and production performance proved that the main fracture development zones inside the volcanic bodies are accurately predicted and described by the seismic-constrain geological model and the coincidence ratio reaches 93.8%.
