In view of the main feature of strong anisotropism of reservoir stratum of the paleozoic era carbonate rock in the middle part of ortos basin gas field , mainly by means of random analog formation , this paper makes a quantitative tranformation on the geological study on the area and the descriptive results of the gas pool , and finishes the whole geological model of underground carbonate rock in ortos basin , including the structure model / phy - sical model and fluid distribution model 摘要针对鄂尔多斯盆地中部气田下古碳酸盐岩储层非均质性强的主要矛盾，以随机模拟建摸为主要方法，对该区地质研究和气藏描述成果进行定量化转变，形成了包括构造模型、物性模型和流体分布模型的鄂尔多斯盆地下古碳酸盐岩整体地质模型。
7 , three - dimension quantificational geology model has been built by means of gauss random modeling method and shown ; at the same time , three - dimension data body has been input into oil reservoir numerical model , and we achieve actual integration study of geology and numerical model 7 、运用高斯型随机建模方法建立了三维定量地质模型，且显示三维地质模型;同时将三维数据体输入油藏数值模拟，实现了地质模型与数值模拟真正的一体化研究，而且地质模型经油藏数值模拟历史拟合验证表明精度高，符合地下客观情况。
Geologic structure modeling is one of the main aim of seismic forward modeling and inversion method , while most of the current modeling systems could not meet the needs of the scientific research and product practices . the geological model input is very complex and very clumsy , so it is high time we solved it by new model description methods and new model input techniques 构造地质模型的建立是地震正演模拟和反演技术的主要目的之一，但目前已有的很多系统尚不能满足科研与生产的实际需要，构造模型的建立尤其是输入工作还是非常繁琐、复杂，缺乏比较先进、实用的模型描述手段和模型输入技术。
The first is to build reservoir geological models for fang 2 area of daqing songfangtun oil field , based on the application of seismic data that is areally dense , and well - log data that provides good vertical resolution . the second is to study the technique details of reservoir geological modeling integrated seismic and well - log data , based on the study of reservoir geological modeling in fang 2 area of daqing songfangtun oi ! field , so that the methods of reservoir geological modeling can be tested and some experience can be accumulated for daqing oil field 本文研究的目的，一是利用横向上具有密集采样的地震数据和在纵向上具有高分辨率的井数据，为大庆宋芳屯油田芳2区块建立较为精确的储层地质模型，对芳葡62 - 34 ?芳48 - 38断块布井方案进行认证；二是通过对大庆宋芳屯油田芳2区块结合地震资料建立储层地质模型的研究，探讨地震与地质资料综合储层地质建模的技术细节，为大庆油田结合地震资料建立储层地质模型进行方法尝试和积累经验。
