During the oil field exploitation , the key of studying reservoir heterogeneity is high accuracy stratum ' s partition and contrast . fine degree of petroleum deposit ' s partition and contrast direct decide cognition ' s deepness and precision of that reservoir 在油田开发过程中，高精度地层的划分和对比是进行储层非均质性研究的关键性工作，油藏层组划分和对比的精细程度直接决定了对本区储层认识的深度和精度。
In this regard adequate shale modeling must be part of a good reservoir description : providing the knowledge of the spatial distribution of heterogeneities in the internal architecture of the reservoir , it becomes a key factor in the production planning and optimized oil recovery 在这方面,适当的页岩模型必定是良好油藏描述的一部分:这种模型能够提供油藏内部非均质性的空间分布信息，非均质性是开发生产规划设计中一个关键的考虑因素
The predictive models of reservoir pore throat volume distribution which can solve the problem caused by shortage of mercury injection sample or core data in certain layer or wells of an area , are proposed and proved to be successful in evaluating heterogeneity of reservoir pore structure 该模型解决了在一个地区部分层段、部分井因缺乏压汞测试样品或岩芯资料给储层孔隙结构研究带来的团难，并有利于正确评价工区储层孔隙结构的非均质性。
With the development of worldwide petroleum industry , deviated holes , branch holes and horizontal wells are used to exploit oil reservoir which is smaller , thinner and worse . logging while drilling ( lwd ) is used to evaluate and geosteering drill in this kind of reservoir because of its characters 随着世界石油工业的不断发展，大斜度井、分支井和水平井等钻井技术越来越多地被用来开发规模更小、油层更薄、物性更差、非均质性强的油藏。
The severe and frequent changes in sedimentary environments ( coal facies ) led to the horizontally and vertically sharp inhomogeneities of the pore system and relevant petro - physical property of coal reservoir , which bring on a very disadvantageous influence on the coalbed methane development in the basin 由于沉积环境（煤相）的剧烈频繁变迁导致了煤储层孔隙系统及相应的储层物性在纵向及横向上强烈的非均质性，给该盆地煤层气的开发带来平重不利影响。
