随着油田的开发,油田注水、采出能耗高,给成本控制带来了难度。在精细地质研究的基础上,结合生产实际对高采出、高吸水的高能耗井采取堵水、调剖措施,降低油井的含水比,提高产油量。封堵或卡堵高含水层,减少油井的层间干扰,改变水驱油的流线方向,提高了注入水的波及体积。增加产油层段厚度,减少高含水层厚度,改善油井的产液剖面;注水井调剖后纵向上控制了高渗透层的吸水能力,低渗透层的吸水能力相应提高,不吸水层开始吸水,增加了注入水的波及体积,扩大了油井的见效层位和方向。整体上改善注入开发效果,达到改善产液剖面和吸水剖面的目的,同时见到了节能效果。
With the development of the oilfield, oilfield water injection, mining high energy consumption, cost control has brought difficulty. On the basis of fine geological study, combined with the actual production of high production, high water consumption wells to take high water cut, profile control measures to reduce the water content of oil wells and increase oil production. Plugging or plugging aquifers, reducing inter-layer interference of oil wells, changing the flow direction of water flooding and increasing the volume of injected water. Increase the thickness of the pay zone, reduce the thickness of the aquifer, and improve the production profile of the oil well. After the injection well is profiled and controlled, the water absorption capacity of the high permeable layer is controlled longitudinally, the water absorption capacity of the low permeable layer is correspondingly increased, Increasing the volume of injected water and expanding the effective layer and direction of the well. As a whole, the injection development was improved and the production profile and water absorption profile were improved. At the same time, the energy saving effect was seen.
