摘　　要：鄂尔多斯盆地地质复杂程度高,储层非均质性强。近年来,虽然在大规模运用水平井开发实践基础上形成了相关的配套开发技术,但未来提升单井产能的技术攻关方向仍不明确。以华庆油田B 452区块采油水平井为例,在钻进过程中利用红外光谱、岩石热解、轻烃、元素四项录井技术,通过实时数据对储层进行综合对比研究分析,优选四项录井技术敏感参数,分别从储层含油性、流体可动性、可压裂性等多维度进行综合解释评价,建立了甜点指数识别流体性质标准,在后期生产应用中储层解释评价精度显著提高,并为水平井钻探积累了宝贵经验,具有一定的借鉴意义。Ordos Basin has complex geology and strong reservoir heterogeneity.In recent years,although the large-scale application of horizontal well development practice has formed relevant supporting development techniques,the technical research direction of improving single well productivity in the future is still unclear.Taking the oil production horizontal wells of B 452 block in Huaqing Oilfield as an example,during drilling process,the four mud logging techniques infrared spectrum,rock pyrolysis,light hydrocarbons,and elements are used to perform comprehensive comparison and research analysis on the reservoirs through real-time data,and sensitive parameters of four mud logging techniques are optimized.The comprehensive interpretation and evaluation are made from the multidimensional aspects of reservoir oil-bearing property,fluid mobility and fracability,and the criteria for identifying fluid properties by sweet spot index are set up.In the later production application,the accuracy of reservoir interpretation and evaluation is dramatically improved,and valuable experience has been accumulated in horizontal well drilling,which has a certain referential significance.
