All wells are arranged in the order of the unit variable cost from low to high . the well whose unit variable cost is smaller than or equals the threshold of unit variable cost and the new well whose unit variable cost is high go into production 全厂单井(除捞油井)按单位变动成本由低到高排序,把中、低成本井、高成本可转捞油井、高成本新井和长期捞油井作为投产单井,投产单井产量总和为优化产量。
The paper includes several parts below : the first part analyzes the characteristic of oil output and the constitution of operating cost , and introduces the forecast model of productivity and operating cost . it makes use of the model of gm ( 1 , 1 ) to forecast the well ’ s productivity and relative variable cost 主要内容包括以下几部分:第一部分,分析油田企业产量的特点和操作成本的构成,阐述了单井产量和成本的预测方法,利用gm ( 1 , 1 )模型预测单井产量和相对变动成本。
