储层评价研究进展

储层研究的最终目的就是对储层作出符合地质实际的分类与评价。储层分类评价的结果可以直接指导油气勘探开发,因此一直是研究者关注的焦点。从国内外研究的现状入手,结合自身的科研实践,介绍了地质经验法、权重分析法、层次分析法、模糊数学法、人工神经网络法、分形几何法、变差函数法、聚类分析法、灰色关联法、各种测井方法和地震方法等11种储层评价研究的方法及其优缺点。研究认为资料的选择、评价参数的选择和评价结果的合理性验证是储层评价研究中尤其值得重视的问题。最后指出了储层评价研究中存在的问题及今后的发展趋势。 

Advances of Reservoir Evaluation Researches

The final aim of reservoir researches is the classification and evaluation of reservoirs in accordance with geological reality.The classification and evaluation will directly guide the oil and gas exploration and development,so the result of reservoir evaluation always is central point of all researchers.With the overview of the present reservoir evaluations home and abroad as well as the author's own practical researches,this paper summarizes eleven kinds of reservoir evaluation methods such as geological empirical approach,weighted analysis,analytic hierarchy process,fuzzy mathematics,artificial neuron of neural network method,fractal geometry,variation function,cluster analysis methodology,gray correlation method,logging methods and seismic techniques.When discussing the advantages and disadvantages of these methods,the paper suggests that the data selection,the evaluation parameter selection and the rational confirmation of the evaluation results should be key points in the reservoir evaluation.At the same time,the paper points out the problems and the development directions of reservoir evaluation researches.
