摘　　要：克拉玛依油田油藏类型复杂多样,通过用指数递减、年绝对油量递减及经验公式等方法研究不同类型油藏产量的递减规律,建立了分类油藏产量预测及控制模型,确定了各类油藏不同开采阶段的合理递减指标,应用预测模型对所对应的油藏产量进行递减趋势预测,并进行产量递减控制因素研究,确定了影响递减规律的主要因素。Karamay oilfield has being developed for over 50 years.Because of complexity of variety of the reservoirs,the production decline patterns for various types of reservoirs still lack of systematic studies,as the result,the deviation between planned production and actual production is very high sometimes.Using exponential decline and annual absolute decline to oil and empirical formula methods,this paper studied the production decline patterns of them,developed the models for prediction and control of production from the classified reservoirs and determined the rational declining indices for various development stages.Through trend prediction of production and analysis of control factors,the main factors influencing the production decline patterns are given in this paper.
