摘要
以冀东油田庙北地区馆陶组油藏地质模型、油藏定量评价模型的建立为例 ,较有针对性地阐述了在河流相沉积的复杂断块区 ,以三维测井约束反演为基础 ,以产能建设为目标 ,按照模式约束、钻井控制、地震导向外推的技术思路 ,应用地质统计学技术 ,充分结合地质、测井、测试等信息 ,定量地研究储层岩性、物性和含油性。同时 ,在三维空间内 ,把构造、储层和油气水特征进行了有效地叠合 ,对油藏位置和特征进行精细描述 ,并建立起定量反映油气田特征的三维可视化模型。经实践检验 ,可大大提高建模精度 ,从而为高速、高效地开发油田 ,动用其地质储量提供了可靠的地质依据 ,为油藏数值模拟和开发方案的编制提供了地质模型 ,并起预测作用。
Taking the reservoir geological modeling and reservoir quantitative evaluation modeling of Ng group in Miaobei,Jidong Oilfield as an example,directing against the complex block fault area of fluvial deposition,to quantitatively study lithology,physical property and oil of reservoir,has been expounded,according to the technical clue of model constraining,drilling control and seismic extrapolate,using geostatistics technology and the information combination of geology,logging and testing,based upon 3 D logging constrained inversion.In the meantime,by the effective superposition of structure,oil reservoir and oil gas water properties in 3 D space,the reservoir position and properties are described accurately and the 3 D video model has been built up,which can quantitatively reflect the properties of oil and gas field.Through examination of practice,the precision of modeling has been largely raised.Thus,the credible geological basis has been provided for high speed and high effective oilfield development and for utilization of geological reserves.And the geological model has been also provided for numerical reservoir simulation to formulate the development plan and play an important role in the reservoir prediction.
