摘　　要：正确评价和优选油井增产措施 ,除了优选地质和油藏条件外 ,还应从经济角度加以论证。根据边际分析理论 ,提出了 2种计算增产措施边际成本的方法 ,分别适用于实际资料丰富和缺乏的情况。并根据边界成本等于边际收益的原则 ,确定出油井增产措施的边际价格以及在现行价格体系下各项措施的取舍条件。由此 ,对油井措施进行评价 ,优选出地质及工艺上可行。In order to correctly evaluate and screen out the stimulation methods for oil wells,economic demonstration should be made in addition to screening geologic and reservoir conditions.Based on the theory of marginal cost analysis,this paper presents two methods for calculating the marginal cost of stimulation,which are suitable for both cases with rich practical data and without practical data.According to the principle of marginal cost equivalent to marginal benefit,it puts forward the marginal price for stimulating mature oil wells and criteria for screening various measures of stimulation under the current pricing system.From this above,the projects which are feasible in geology and technology and good in economic benefit can be screened out.This method has been confirmed by practice.
