提出一种生产测井多井解释方法 ,综合分析不同井点、不同时间测量的生产测井资料研究油藏生产过程中的动态变化规律。该解释方法包括三部分 :①多井资料标准化处理部分对不同测量条件、时间生产测井资料进行标准化处理 ,使得多井资料具有可比性。②多井对比部分根据油层物性相似性和相关性提取对比因子构成对比因子序列 ,应用关联度分析方法确定油层横向连通性。③油层生产动态评价部分首先根据渗流规律预测单井剩余油饱和度和产能 ,然后应用多井资料和平面预测方法进行油层生产动态评价 ,最后对某油田某区块多井资料的实际处理解释。单井剩余油饱和度计算结果与岩心实验结果对比表明预测效果较好 ,文中提出的主作用因素分析方法比趋势面分析和分形克里金预测方法预测结果更为合理。图 2表 1参 5
A method for multi-well interpretation of production logging is proposed. The production logging data measured at different well points and at different times are comprehensively analyzed to study the dynamic changes in the process of oil production. The interpretation method includes three parts: ①Multi-well data standardization processing part of the different measurement conditions, time production logging data standardization, making multi-well data is comparable. (2) Multi-well contrasts extracted comparative factors according to similarity and correlation of reservoir physical properties to form contrast factor series, and applied correlation analysis method to determine lateral connectivity of reservoir. (3) The dynamic evaluation of oil production firstly predicts the residual oil saturation and productivity of single well based on the seepage law. Then the multi-well data and plane prediction method are used to evaluate the production status of oil production. Finally, the multi-well data of a block is treated and explained. The results of single-well residual oil saturation calculation and core experimental results show that the prediction effect is better. The main factor analysis method proposed in this paper is more reasonable than the trend surface analysis and the fractal kriging prediction method. Figure 2 Table 1 reference 5
