| 摘 要： | 为了研究堵剂在发生管外窜槽井的注入特性,根据管外窜槽模型,分析了低粘度堵剂的注入特性,指出不同渗透率地层的分流情况受窜流通道和地层渗透率的综合影响.在油水层渗透率一定的条件下,窜流通道渗透率越小,水窜层分流率越小;反之,窜流通道对水窜层分流率影响越小,并且最终分流率趋于定值.随着注入速度的增加,水层和油层的压力均增大.在窜流通道和油水层渗透率一定的条件下,若油水层压力不变,则油水层分流率不变.低粘度堵剂注入发生管外窜槽的油水层时,由于油水层压力确定了注入流体的分流率,同时由于油层压力小于水窜层压力,使大量堵剂进入油层,对地层造成严重伤害.因此,建议使用泡沫等具有分流效应的流体,减少对油层的污染. |

| Abstract: | In order to study the injection characteristics of the plugging agent in the event of pipe outside of the channeling wells, and according to the outside of the tube channeling model, the low viscosity plugging agent injected characteristics are studied herein, it is pointed out that the fluid branching within different permeability stratum condition is influenced comprehensively by the channeling circulation and permeability stratum. Under certain conditions of oil-water layer permeability, the smaller the ... |
