小型边水稠油油藏单井液量优化方法

Optimization Method of Single Well Fluid Production in Small Edge Water Heavy Oil Reservoirs

小型稠油边水油藏可实施的增产措施具有一定的局限性,产液量优化具有工期短、成本低的特征,为实现小型稠油油藏经济、有效的开发,开展小型稠油边水油藏合理产液量的研究。以W油田工区为例,考虑构造位置对边水推进的影响,采用传统配产技术与实际生产情况相结合的方式,优化单井产液量,延缓边水突进速度,提高水驱波及面积,改善W油田小型稠油边水油藏开发效果,为同等类型油藏的液量优化提供参考。

The feasible stimulation measures for small heavy oil edge-water reservoirs have certain limitations. The optimization of liquid production has the characteristics of short construction period and low cost. In order to realize the economic and effective development of small heavy oil reservoirs, the reasonable liquid production for small heavy oil edge-water reservoirs is studied. Taking W oilfield as an example, considering the influence of structural location on edge water propulsion, traditional production allocation technology is combined with actual production situation so as to optimize the fluid production of single well, delay the inrush speed of edge water, increase the sweep area of water flooding, and improve the development effect of small heavy oil edge water reservoirs in W oilfield,which provides reference for the optimization of liquid volume in the same type of reservoirs.
