摘要
扶长停井产能经济界限测算方法通常只考虑了经济上的充分条件,忽视了其必要条件,使其不能完全满足矿场实践的需求。文章从充要条件出发推导了扶长停井产能经济界限的计算公式,考虑了措施有效期和含水率2个影响因素,确定了可变成本和固定成本的具体计算方式,并制作了临2块不同油价、不同投资条件下扶长停井产能经济界限图版,满足了恢复长停井判别原油经济生产能力的需要。在原油价格为3100元/t的情况下,应用该方法测算了胜利油区断块油田目前1147口长停井恢复原油生产能力的潜力,有537口井可以扶停,年恢复原油生产能力为44×104t。
The method of calculating the economic threshold productivity of the long-closed well after recovery can not meet the demand of field practice completely for only considering the adequate condition on economy but ignoring other necessary conditions.According to the adequate and necessary conditions,the author deduced the formula of economic threshold productivity of the long-closed well after recovery.Computational method of variable cost and constant cost was established based on the validity term of the measures and the water cut.And,a graph of economic threshold productivity of the long-closed well after recovery was worked out under different oil prices and investment condition in Lin2 block.It meets the need of determining the economic threshold productivity of the well.Applying the provided method,1 147 long-closed wells in fault blocks of Shengli Oilfield were estimated.And the results show that 537 wells can be recovered at the price of 3 100yuan/t,with well production recovering ability of 440×104t.
