测井二次解释模型在储量套改中的应用

中国各油区储量套改一般采用岩心分析资料刻度测井资料的思路来建立二次解释模型，即应用数理统计的方法，建立测井和岩心分析资料之间的关系，然后应用这些关系进行定量解释和计算机处理。着重讨论了应用岩心分析和测井资料建立二次解释模型中的主要技术问题，即单元和多元线性回归分析、测井曲线校正及资料标准化方法和深度归位。利用胜利油区陈家庄地区的80多口井岩心、试油和测井数据，计算了主要的储层参数，平均绝对误差均低于1．3％，解释吻合程度达到了89％。所建立的测井二次解释模型的解释精度可满足储量套改的要求。

Application of secondary logging interpretation models in reserves standard exchange

During the reserves standard exchange of each Chinese petroliferous province, secondary interpretation model is built with the idea of well logging information calibrated by core analysis. That is,using the method of mathematical statistics makes the relations between the well logging data and core information, then quantitative interpretation and computer process can be made using these relations. Key technical problems of the secondary interpretation model are discussed which is built on core analysis and well-logging information. For example, single unit and multiple regression analysis, well log correction and information normalization method and depth matching. The key reservoir parameters are calculated for more than 80 wells in Chenjiazhuang area of Shengli petroliferous province based on their data of core, testing and logging. The average absolute errors is all lower than 1.3% and coincidence degree of the interpretation is up to 89%. The interpretation precision of the formed secondary interpretation models may meet the demands of reserve standard exchange.
