RMS软件在铁边城地区长4＋52储层建模中的应用

Application of RMS Software to Geological Simulation of Chang 4＋52 Reservoir of Tiebiancheng Region

利用RMS随机建模软件对鄂尔多斯盆地铁边城地区长4＋52储层开展了三维储层建模研究。根据三角洲前缘沉积的特点．运用序贯指示模拟方法，建立了沉积相模型；并利用70余口井的测井解释成果与岩心分析数据，通过数据分析、正态变换、变差函数分析．在沉积相建模的基础上采用序贯高斯模拟方法研究了储层孔隙度、渗透率的空间分布．较好地再现了储层的非均质性，为评价井的优化部署与随钻调整以及开发方案的优化设计提供了基础。储层模拟结果表明．RMS储层建模软件具有方便、实用、可信度高的特点。

Researches of establishing a 3D model of Chang 4＋52 reservoir in Tiebiancheng region of Ordos basin are carried out by using the RMS software for random modeling. In the light of characteristics of delta front sedimentation, a sedimentary facies model is established by using the method of sequential indicator simulation. By utilizing log interpretation results and core analysis data of more than 70 wells, and through data analysis, normal transformation, and variance function analysis, the spatial distribution of porosity and permeability is studied by adopting sequential Gaussian simulation method, on the basis of sedimentary model establishment. Heterogeneity of the reservoir is well restored. It provides groundwork for optimal arrangement and adjustment with drilling of appraisal wells, and for the optimal design of development programs. Simulation results show the RMS modeling software is convenient, practical, and of high reliability.
