| 摘 要： | 我国低渗透油田、低产油井的数量逐年增加，而对注水开发低渗透油田的油井流入特性认识的不足或者是重视得不够。建立了新型通用油井流入动态方程，得出了油井流入特性曲线存在拐点的判别条件与最大产量所对应合理流压的计算方法。应用新型油井流入特性曲线指导油井抽汲参数设计，确保油井在合理流压下生产，可以实现油井产量最大化，提高低渗透油...

| Abstract: | In China＇s oil fields, the numbers of oil wells of low liquid output and low permeability are increasing year by year, but the behaviors of the well inflow performance relationship of low permeability oilfield are not researched perfectly or are not paid attention to in designing the pumping parameters. In the paper, a new type of well inflow performance relationship is setup. The relationship equation that is used to distinguish whether or not the inflow performance relationship is of inflection point is established, and the formula of calculating the reasonably flowing pressure at which the liquid output can get the maximal value is setup. When the new inflow performance relationship is used to direct the design of suction parameters of rod pumping wells, the oil wells can run at the reasonably flowing pressure and the maximal liquid output, which is of important significance to raise economic effects of low permeability oil field. |
