摘要:
中东H油田Mishrif组属于典型的孔隙型生物碎屑灰岩储层,水驱是目前主要的开发方式,但注入水中固相颗粒的质量浓度及粒径严重影响其开发效果。为了弄清注入水对储层物性的影响,并为后期注水开发的水质要求及调整方案设计提供依据,文中基于恒速压汞实验及颗粒运移实验,研究了影响H油田Mishrif组储层渗流能力的主要微观因素以及注入水中悬浮物颗粒质量浓度与粒径的上限,并且分析了悬浮物颗粒粒径与喉道的配伍性。研究结果表明,喉道半径及分布是影响储层渗流能力的主要微观因素。当注入水中悬浮物颗粒粒径为5 μm时,颗粒质量浓度的上限为5 mg/L;当悬浮物颗粒质量浓度为3 mg/L时,颗粒粒径的上限为10 μm,接近于渗透率贡献峰值处的喉道半径。
Abstract:
The Mishrif Formation of H Oilfield in the Middle East is a typical porous bioclastic limestone reservoir. Water drive is the main development mode at present. However, the concentration and size of solid particles in injected water seriously affect the development effect of water drive. In order to understand the influence of injected water on reservoir physical parameters and provide basic parameters for water quality requirement and adjustment scheme design of later water-flooding development, based on the experiments of constant-rate mercury injection and suspended particles migration during water-flooding, this paper studies the main micro factors affecting the permeability of the Mishrif Formation in H Oilfield, as well as the upper limit of the concentration and size of suspended particles in the injected water. The compatibility between the particle size of suspension and throat was analyzed. The results show that the pore size and distribution of the throat are the main micro factors affecting the permeability of the formation. When the particle size of suspended solids in the injected water is 5 μm, the upper limit of particle concentration is 5 mg/L. When the concentration of suspended particles in the injected water is 3 mg/L, the upper limit of particle size is 10 μm, which is close to the throat radius at the peak of permeability contribution.
