摘　　要：以现河采油厂稀油为例回归出自然递减率与综合递减率的线性关系式 ,在定井跟踪确定综合递减率的基础上 ,能较快计算出所对应的自然递减率 ,同时能快速预测出新井和措施增油量占总产油量的比例 ,根据措施单井次增油量和新井单井增油量变化规律 ,即可确定措施和新井工作量。Linear relational expression between natural decline rate and composite decline rate is regressed taking thin crude oil in Xianhe oilfield as an example. On the basis of determining composite decline rate by tracing for fixed well, the corresponding natural decline rate will be calculated more quickly. The proportion of incremental oil production for new wells and stimulated wells to total oil production will be predicted at the same time. The workload of stimulated and new wells can be determined according to the changing rules of incremental oil production for stimulated singlewelltimes and new single well. The predictions for the above all have important significance in programming the longterm planning.
