摘要
采油速度是油田开发方案制定、措施调整、动态分析、指标预测等一项重要的开发指标。综述了确定理论采油速度的5种方法，提出了利用动态资料确定理论采油速度的新方法，从直线相关与曲线相关2个方面利用相关系数法与灰色关联分析法分析了采油速度的主要影响因素。结果表明影响特高含水期采油速度最主要的因素是采液速度，其次是注水速度，再次是注采井动压差。提出的方法及分析的结果对油田特高含水开发理论研究与实际应用具有一定的参考价值。
Oil production rate is one of the important developing indexes for oilfield development programing, ad- justing measures, dynamic analyses, index prediction and so forth. Five kinds of methods to determine the theoreti- cal production rate are comprehensively discussed, and furthermore a new method of using dynamic data to deter- mine the rate is put forward ： the main influencing factors of the production rate are analyzed from two aspects of the linear and the curve correlations with the help of correlation parameter and gray correlation analyzing methods. The achievements show that the most important influencing factor on the oil production rate at super-high water-cut stage is fluid production rate, the next is water injected rate, the least is the dynamic differential pressure between the in- jectors and producers. The proposed methods and the analyzed results have a certain reference values for the theo- retical researches and actual application at the super-high water-cut stage of an oilfield development.
