摘要: 随着过热蒸汽吞吐已经进入工业化应用,关于过热蒸汽吞吐产能的研究需求增加。在直井过热蒸汽吞吐加热半径计算模型基础上,将油藏内热区和冷区内渗流分开计算。冷区稠油由供给边界流向热区边界,热区稠油由热区边界流向生产井底。利用有界地层中心一口井不稳定渗流微分方程的拟稳态解得到产能模型。利用本文方法对库姆萨伊油田目标区块两个吞吐周期进行定油拟合计算,累计产水量计算值与实测值相对误差均小于0.5%。

Abstract: The superheated steam has been applied in the industrial application, and the demand for the study on the production capacity is increased. Based on the studies of radius calculation, the hot zone and cold zone have been calculated separately. The cold oil flows from the supply boundary to the hot zone, and then flows through the hot zone to wellbore. The quasi steady state solution has been used to solve the problem. Using the model to calculate oil productivity for two cycles in KMK oil field, the relative error of cumulative water production is less than 0.5%.
