摘要
以长庆G油田L井区的典型低渗透油层为研究对象,针对其储层的影响因素多,关系复杂等特点,应用模糊数学的方法,在已取得的储层的17项参数的基础上,对其进行了多因素综合评价。研究筛选出13项影响储层评价的主要因素,采用模糊数学的方法,利用SPSS分析软件,对G油田H储层进行了综合评价。最终筛选出了5个贡献最大的因子,并将储层分为3大类。该方法对储层分类具有很高的可靠性,其分析评价结果与单井试油结果的符合率达90%以上。基于综合评价的结果,对G油田H油藏进行开发,实施效果较好。
An integrated method was provided for comprehensive evaluation of the multiple factors affecting low permeability reservoirs in L Wellblock of G Oilfield in Changqing,by using fuzzy mathematic methods,the study was based on 17 parameters,the reservoirs were integrally evaluated,13 parameters were chosen as the main factors for the comprehensive evaluation in consideration of the result of correlation analysis.Fuzzy mathematic methods were applied by using SPSS software for the comprehensive evaluation and the prediction of H reservoir of G Oilfield.Five largest contributing factors for reservoir characterization was determined,and the reservoirs were subdivided into 3 types.The method is reliable in the prediction of favorable reservoirs,and the classification results are proved to be consistent with the outcome of individual well production rate with a coincidence rate over 90%.The method of the comprehensive evaluation using fuzzy mathematics is determined as an effective and desirable way for development of H reservoir in G Oilfield.
