【摘要】：冀东油田经过二十余年的开发,其油藏内部结构异常复杂,确定油层水淹状况及剩余油的分布需要进行油藏精细解释。前人在水淹层解释与评价方法方面已经做了大量研究工作,目前处于较成熟阶段,但在水淹层测井解释模型建立方面仍多依赖经验公式及一元回归等基本方法。在油田开发已达到高含水、特高含水阶段的今天,经验公式和一元回归等方法对模型的分析力度已不能适应实际地层情况。针对以上问题,本课题主要利用检查井和对比井的区域地质资料、岩心资料、实验室分析化验资料、测井资料和生产动态资料等,在对研究区储层四性特征(包括岩性、物性、电性、饱和度)和储层四性关系进行分析的基础上,选取了泥质含量、孔隙度、渗透率、含水饱和度和剩余油饱和度等参数来建立测井解释模型,并就建立水淹层测井解释模型的方法(包括岩电参数法、数理统计法等)进行大量试验,同时结合储层四性特征及关系的分析结果,优选出多元逐步回归法来建立研究区特高含水阶段储层测井解释模型,避免了依赖经验公式导致的不适用实际地层的问题;最后用交会图、取值分布图和绝对误差三种方法,从定性和定量两方面评价了多元逐步回归法建立的模型在研究区的应用效果,结果证明模型的应用效果良好,均符合生产要求。
[Abstract]:After more than 20 years of development, the internal structure of Jidong oil field is very complicated, so it is necessary to make fine interpretation to determine the water-flooded condition and the distribution of remaining oil in Jidong Oilfield. Many researches have been done on the interpretation and evaluation methods of water-flooded zones, and they are still in the mature stage. However, the establishment of logging interpretation models for water-flooded zones still relies on empirical formulas and univariate regression methods. At the stage of high water cut and super high water cut in oilfield development, the analytical strength of the model by empirical formula and univariate regression method can no longer adapt to the actual formation situation. In view of the above problems, this subject mainly uses the regional geological data, core data, laboratory analysis and laboratory data, well logging data and production performance data of the inspection well and the contrast well, etc., in order to analyze the reservoir characteristics (including lithology, physical property, etc.) of the reservoir in the study area. Based on the analysis of the relationship between electricity, saturation) and reservoir, the logging interpretation model was established by selecting the parameters of mud content, porosity, permeability, water saturation and remaining oil saturation. A large number of experiments have been carried out on the methods of establishing logging interpretation model of water-flooded zones (including rock electrical parameter method, mathematical statistics method, etc.), at the same time, combined with the analysis results of the four characteristics of reservoir and the relationship between them, The multivariate stepwise regression method is selected to establish the reservoir logging interpretation model in the study area at the very high water cut stage, which avoids the problem of not applying the actual formation caused by relying on the empirical formula. Finally, three methods, cross plot, value distribution map and absolute error, are used. The application effect of the multivariate stepwise regression model in the study area is evaluated qualitatively and quantitatively. The results show that the application effect of the model is good and meets the requirement of production.
