摘　　要：勘探初期,存在井数少、生产资料缺乏等问题,给生产预测带来一定难度。以油井早期试油数据为基础,结合油藏物质平衡原理、自喷油井协调生产理论,以及Standing油井流入动态预测方法,通过时间离散化处理,建立了自喷井早期生产动态预测模型和预测方法。大港油田7口自喷井的早期生产预测结果表明,在油井工作制度保持不变的情况下,产液量平均预测误差在-11.6%～10.53%之间、产油量平均预测误差在-12.81%～12.95%之间,可满足现场生产的需要。该预测方法对指导新区开发具有一定的应用价值。Problems of few of wells and lack of enough production data are existed at early exploration time,which brings a certain difficult to implement such prediction. Base on the well test data,combining with material balance equation,nodal analysis and Standing future IPR prediction method,the performance prediction model and methodology of flowing well in its early production stage are established by time discretization processing. Predicting their production of seven flowing wells in Dagang oilfield,the results show that the average prediction error of liquid production rate is between-11. 6% and 10. 53%,and between-12. 81% and 12. 95% for oil production rate under condition of stable work system which can meet field production need. The proposed method has a certain applied value to guide the development of the new exploration area.
