摘　　要：录井参数的多样性评价储层难点在于参数归一化及定量评价。潜山储层的非均质性难以建立统一模型,储集空间的多样性使单纯应用宏观物性特征评价潜山储层的有效性受到限制。研究提出物性指数P表征潜山储层的物性,采用正向参数覆盖面积方法对气测录井、地球化学录井、三维定量荧光录井、元素录井、衍射录井等多参数融合评价潜山储层含油气性,综合潜山储层物性和含油气性确定潜山有效储层的标准,给潜山储层有效性的评价提供一种新的方法。在丽水-椒江区块钻遇基底的16口井应用了多参数融合潜山储层有效性评价方法,建立了丽水-椒江区块潜山储层有效性评价标准,将此标准应用于新钻井的解释评价,符合率达到94.4%,取得了较好的应用效果。The difficulty in reservoir evaluation with the diversity of mud-logging parameters lies in parameter normalization and quantitative evaluation of these parameters.The heterogeneity of buried hill reservoir makes it difficult to establish a unified model,and the diversity of reservoir space limits the effectiveness of evaluating buried hill reservoir by simply applying macroscopic physical property characteristics.The physical property index P is proposed to characterize the physical property of buried hill reservoirs.The positive parameter coverage area method is used to evaluate the oil and gas properties of buried hill reservoirs by multi-parameter integration of gas logging,geochemical logging,three-dimensional quantitative fluorescence logging,element logging,diffraction logging,etc.The physical properties and oil-bearing properties of buried hill reservoirs are integrated to determine the standard of effective buried hill reservoirs,which provides a new method for evaluating the effectiveness of buried hill reservoirs.The multi-parameter fusion method for evaluating the effectiveness of buried hill reservoirs was applied in 16 wells that encountered basement in Lishui-Jiaojiang block,and the evaluation standard of buried hill reservoir effectiveness was established.The standard was applied to the interpretation and evaluation of new drilling,and the coincidence rate reached to 94.4%,which achieved good application results.
