摘要
低渗透油田地质特性复杂，油气储层产能受多因素影响，使储层的产能预测相对困难，主要通过测井曲线与产能单因素的相关分析，寻找产能主要影响因素，再通过数学物理方法建立起产能与主要影响因素之间的模型，最终建立了预测储层产能的综合指数法预测模型．形成使用方便、适用范围广泛的测井产能预测方法。经对华庆油田白455井区25口井预测应用．取得较好的应用效果。
The geological properties of the low-permeability oil field are eomplex, and the capacity of the oil/gas reservoir is influenced by many factors, which makes the capacity prediction of the reservoir be difficuh. This article fnds tire main factor influencing tile capacity through the relative analysis of the well logging curve and the single capacity factor＇, establishes the mode between the capacity and main influence factors through the mathematical and physieal methods, and finally establishes the integrated index predicting mode which predicts the capacity of the reservoir, and then the predicting method for measuring the well capacity with convenient utilization and wide applying range is formed. Through the predicting application of 25 wells of the Bai 455 well area in Huaqing oil field, the good applying effect is achieved.
