摘要
注水开发油田进入高含水期后，开发矛盾日益突出，稳产的形势较严峻，剩余油在空间上分布十分复杂，挖潜难度越来越大，油田必须要走精细开发的路子，而油水井产量劈分是多层油藏精细开发的基础。从渗流力学基本理论出发，建立多层合采井分层流量计算理论模型，分析各因素对分层流量变化规律的影响；并在理论研究基础上，结合油田开发的实际情况，提出了油水井产量劈分的具体指导原则，对现场多层合采油井产量进行了劈分工作。对于油田精细开发具有一定的指导意义。
After entering into the high water cut stage, the development contradictions of the water flooded oil field become obvious day after day, the sustainable oil production is more serious and the special distribution of residual oil turns to be very complicated, so it is difficult to tap the potentials. Just according to the above conditions, the way of fine development must be followed, but production allocations of oil and water wells is the basis of the fine development of muhilayer oil reservoir. Therefore, from the basic theories of flow dynamics, the calculating theoretical model of separate flow rate in multilayer commingled wells is established, the influences of each factor on the flow rate changing laws of separate layers are analyzed; and furthermore on the basis of theoretical studies, integra- ting with the actual development performance, the specific guiding principles for the above allocations are pointed out and then the field allocations are conducted in the commingled production wells. All the achievements will guide the fine development of the oilfield.
