回灌盐度和水头对咸水储层渗透性能的影响
|
摘要
针对咸水储层由于水质类型复杂及粘土矿物成分的存在,在回灌溶液盐度改变的情况下,含水层多孔介质内发生胶体粘粒释放,引起储层渗透性能和传热特性改变的问题,搭建一维渗流砂柱实验系统,研究粘土矿物成分、回灌盐度和回灌水头对砂样渗透性能的影响,得到含有蒙脱石砂样的渗透系数随回灌盐度的实验关联式。结果表明:咸水储层渗透性能变化的主要影响因素是粘土矿物的类型和含量以及回灌溶液盐度的变化,回灌水头对咸水储层渗透性能的影响较小。在粘土矿物成分中蒙脱石导致储层渗透性能降低幅度最大,其次是伊利石和高岭石;蒙脱石的含量越多,储层渗透性能降低越显著。
Due to the complexity of the water quality and the composition of clay minerals in brine aquifer,when the injection water salinity is different from the underground brine water,there will be the release of colloidal particles,which could result in the reduction of the permeability and affect the heat transfer characteristics of the brine aquifer. In this paper,an experimental study was carried out using sand column to study the influence of the clay minerals,injection salinity and water head on the permeability of the sand samples,imperial relations of the permeability coefficient were got. Results indicate that the main factor that affects the permeability of the brine aquifer are the clay mineral type and its proportion,as well as the injection salinity,while the injection water head has less effect on the permeability. Among the composition of clay minerals,montmorillonite leads to the largest permeability reduction,followed by illite and kaolinite. The more proportion of montmorillonite is,the more obviously reduction of the permeability is.
