灰色系统理论在科尔沁油田储层综合评价中的应用

Application of grey system theory in comprehensive evaluation formation of Ke'erxin oilfield

方法依据灰色系统理论、测井地质综合评价分析准则和自动处理方法，分析了科尔沁油田交２断块九佛堂组储层及其资料；利用建立的评价解释参数、标准、权系数和自动分析解释系统，对该区断块２０多口井主要目的层段储层进行了综合评价处理。目的为该区断块进一步勘探开发提供地质依据。结果通过对该区断块２０余口井主要目的层段储层进行综合评价和实际处理，建立了储层综合评价的解释参数、标准、权系数和自动分析解释系统，经应用获得了较为满意的效果。结论利用灰色系统理论，能够为该区交２断块九佛堂组储层作出较为可靠的地质解释和评价。

Method Based on logging and geological comprehensive evaluation/analytical guidelines with grey system theory and automatic processing methods, Jiufotang formation of Jiao 2 fault block, Ke'erqin oilfield and its data are analyzed. In addition, target intervals of more than 20 wells in this fault block are evaluated comprehensively by using established evaluating/interpretation parameters, criteria, weighted coefficients and automatic analytical system. Purpose To provide geological basis for next stage exploration and development of this fault block. Result With comprehensive evaluation and practical processing of targeted over 20 wells, interpretation parameters, standard weighted coefficients and automatic analytical system have been established and achieved relatively satisfactory results after application. Conclusion in Jiufotang formation of Jiao 2 fault block, reliable geology interpretation and evaluation results can be obtained through the application of grey system theory.
