灰色理论在辽河油田滩海区储层评价中的应用

利用测井资料对辽河油田滩海区十几口油井主要储层进行了精细评价及匹配、拟合和提取参数,并建立了该区储层岩性、物性、含油性及储层质量评价的解释标准、权系数和指标.岩性精细评价总体上与该区钻井取心及地质录井资料一致,储层物性、含油性及盖层质量评价解释结果也与相应的试油结论吻合.在此基础上,着重分析了该区储层特点、储层质量和物性及含油性的关系,阐明了该区油气层分布规律,为该区进一步勘探开发提供了可靠的依据.

Application of grey theory in the evaluation of the reservoirs in Tanhai area, Liaohe Oilfield

Fine evaluation, matching, fitting and parameter extraction of the main reservoirs are performed according to well logging data of more than 10 wells in Liaohe oilfield. And the interpretation standards, weight coefficients and indexes are developed for the evaluation of the lithology, physical property, oil bearing property and quality of the reservoirs. The evaluation results of reservoir lithology coincide with drilling core and geologic log data, and the physical property and the evaluation results of oil bearing property are identical to oil testing results. The relationship between the characteristics and quality of the reservoirs and their physical property and oil bearing property is analyzed and the law of oil and gas distribution in the area is described, which provides reliable basis for the further exploration and development of the area.
