作业过程中低含水生产井由于受大量外来流体的影响,破坏了地层原油流动孔道内的原始环境,对储层渗透率造成伤害,使作业后油井产液较难恢复、产液量下降。通过对低含水生产井作业过程中储层伤害因素分析,寻找解决措施和方法,从而提高低含水生产井的作业储层保护效果。
During the operation, the low water-bearing production wells, due to the influence of a large amount of extraneous fluids, undermine the original environment in the crude oil flow tunnel and damage the permeability of the reservoir, which makes it difficult for oil production wells to recover and reduce the liquid production after operations. Through the analysis of reservoir damage factors during the operation of low-water-producing production wells, the solution measures and methods are sought to improve the operational reservoir protection effect of low-water production wells.
