摘　　要：针对青海涩北气田的油藏特点和出砂现状,选择涩北岩心进行出砂实验,考察采气速度、渗透率、含水饱和度等出砂影响因素。利用灰色关联分析方法对涩北气田的出砂影响因素进行分析,得出各种影响因素与出砂的关联度。分析发现,含水上升与采气速度对涩北气田的出砂影响较大,应做好控水工作,并严格控制采气速度。通过寻找这些因素与出砂之间的内在关系,可以有目的地创造良好的生产条件或采取措施(纤维复合防砂技术)来避免或减缓出砂,并对类似涩北气田气藏的合理开发提供指导与借鉴。Sand production experiments have been conducted with cores from Sebei gas field to study the influencing factors on sand production, such as gas production rate, permeability and water saturation, etc. Grey correlation analysis method is employed to analyze the influencing factors of sand production in Sebei gas field, and the degree of association between these factors and sand production is obtained. It is found by analysis that the rise of water cut and gas production rate have bigger effect on sand production in Sebei gas field, so that water control is important and gas production rate must be strictly controlled. Understanding the intrinsic relations between these factors and sand production is helpful to creating good conditions of production or adopting measures (e.g., fiber-compound sand control technique) to avoid or reduce sand production, and guide rational development of Sebei gas field.
