【摘要】：在渗流理论方程的基础上,引入艾富罗斯实验结果,并结合Willhite,Chierici等人提出的油相相渗关系式,导出了双曲递减、指数递减、调和递减方程及其对应水相相渗关系式。研究结果表明,油、水两相相渗关系式共同决定着水驱油田产量递减方程;以往的产量递减方程渗流理论研究中,油相相渗关系式不是以出口端含水饱和度为自变量的行业标准相渗关系式,而是以平均含水饱和度为自变量的拟相渗关系式。通过吐哈鄯善油田三间房组油藏、吉林红岗油田萨尔图组油藏、大港马西油田沙一下段油藏的应用,实际产量与油水两相相渗关系式分别确定的递减方程基本一致,值得其他油田在递减规律研究中借鉴。
[Abstract]:Based on the theoretical equation of percolation, the formula of hyperbolic decline, exponential decline, harmonic decline and their corresponding water phase permeability relations are derived by introducing the results of Efferos experiment and combining with the oil phase permeability relation proposed by Willhite,Chierici et al. The results show that the relationship between oil and water phase and permeability determines the production decline equation of water drive oil field, and in the previous study of seepage theory of production decline equation, The oil phase permeability relationship is not an industry standard phase permeability relationship with water saturation at the outlet as independent variable, but a pseudo-phase permeability relationship with the average water saturation as an independent variable. Through the application of Sanjianfang formation reservoir in Tuha Shanshan oilfield, Saltu formation reservoir in Honggang oilfield, and the lower Shahejie reservoir in Dagang Maxi oilfield, the decline equations of actual production and oil-water two-phase permeability relationship are basically the same. It is worthy of reference in the study of decline law in other oilfields.
