灰色理论评价储层解释系统从油藏工程的基本概念出发,以测井解释理论、方法为依据,采用新的测井储层精细评价分析方法、技术及准则,自动拟合储层地质参数解释模型,生成岩性评价指标和系数。文章利用灰色理论评价储层系统,结合中原油田203断块测井资料、实际岩心资料及有关地质参数,通过匹配、拟合和提取参数,以统计分析特征值及其准确率、进行该区块岩性综合解释。岩性评价结果和钻井取芯分析结果吻合率达85%以上,为该区块进一步勘探,制定开发方案奠定了基础。此外,利用灰色理论和方法划分地层岩性和岩性组合时,能够较为准确的获得岩性柱状图和岩性描述,为多参数储层精细评价奠定了基础。它不仅可用于油、气、水的综合评价,而且还能分析沉积环境,绘制油田岩相图件,进行井组间对比,确定勘探油气方向,具有广阔的应用前景。
灰色理論評價儲層解釋繫統從油藏工程的基本概唸齣髮,以測井解釋理論、方法為依據,採用新的測井儲層精細評價分析方法、技術及準則,自動擬閤儲層地質參數解釋模型,生成巖性評價指標和繫數。文章利用灰色理論評價儲層繫統,結閤中原油田203斷塊測井資料、實際巖心資料及有關地質參數,通過匹配、擬閤和提取參數,以統計分析特徵值及其準確率、進行該區塊巖性綜閤解釋。巖性評價結果和鑽井取芯分析結果吻閤率達85%以上,為該區塊進一步勘探,製定開髮方案奠定瞭基礎。此外,利用灰色理論和方法劃分地層巖性和巖性組閤時,能夠較為準確的穫得巖性柱狀圖和巖性描述,為多參數儲層精細評價奠定瞭基礎。它不僅可用于油、氣、水的綜閤評價,而且還能分析沉積環境,繪製油田巖相圖件,進行井組間對比,確定勘探油氣方嚮,具有廣闊的應用前景。

Grey-theory explaining system for reservoir evaluation bases on the basic concept of reservoir engineering and log interpretation theory.It uses a new logging reservoir evaluation and analysis methods,techniques and guidelines.The system can automatically match geological reservoir parameters-explaining model,and then produce lithology evaluating indicators and co-efficients.This study matched,fitted and extracted reservoir parameters,then statistical analysed the eigenvalues and ites accuracy to comprehensively explained the lithology of 203 block in Zhongyuan oilfield by using the grey-theory explaining system for reservoir evaluation,logging data,actual core data and geologic patameters.The matching rate of lithology evaluating result and drilling-core analysis result can reach more than 85 %.The result made a foundation for the further exploration and developing-program formulation in the block.In addition,it can obtain more accurate histogram and description of the rock lithology when using grey theory and method to divide the lithologic combination and stratum lithology.At the same time,it make a foundation for multi-parameter precise evaluation of reservoir.The grey-theory explaining system for reservoir evaluation can be used not only in oil,gas and water comprehensive evaluation,the analysis of sedimentary environment and the oil-facies map drawing,but also in the well group comparison and the determination of direction of oil and gas exporaion.So,the grey-theory explaining system for reservoir evaluation has a broad application prospects.
