摘要(Abstract)：

萨中地区从上到下共发育144个沉积单元,断裂系统复杂,整体动用程度高、含水高,在断层附近剩余油富集,是挖潜调整的主力区。三维地质建模过程中,首先建立构造框架模型,保证断层与地震解释结果的一致性,再利用井震结合的油层组顶面构造数据,建立油层组构造模型,进而利用井点细分层数据,建立各沉积单元的精细构造模型。然后利用指示克里金算法,模拟储层的空间展布。最后应用井点钻遇的油水界面数据,即油底和水顶数据,依据构造油藏特点建立油水分布的空间模型。利用相控条件下的序贯高斯(SGS)模拟算法,模拟储层属性参数的空间分布。该研究成果为断层区大斜度井设计提供了高精度的三维地质模型。
One hundred and forty four sedimentary units are well developed in Sazhong Block from top to bottom,which are characterized by the complex fault system,high wholly-developed degree and high water cut. The remained oil is enriched nearby,so the fault blocks are turned into the main potential tapping area. The framed model was first built for the structures to ensure the accordance between the faults and seismic interpreted results,by the well-seismic integrated structural data of the top of the oil groups,the structural model was built for the oil groups,by means of the finely separated layer data of the well points,the fine structural model was built for each sedimentary unit. And then helped by indicating Kriging algorithm,the spacial distributions of the reservoirs were simulated; Finally with the help of the oil and water interface data of the penetrated well points i. e. the data of the oil bottom and water top,by the characteristics of the structural oil reservoirs,the spacial model was built for the oil and water distributions. and moreover by means of SGS simulating algorithm under the condition of the phase control,the spacial distributions of the reservoir attribute parameters were also simulated. The study achievements have provided the high-precision 3D geological model for the design of the high-inclination well in the fault block.
