油田出砂会影响油田的采油率与采油速度。引发油田出砂有多种原因,例如有岩石物性、地层压力、水侵与气侵等。笔者在本文主要分析了水侵对油田出砂产生的影响。水侵对油田出砂有多种影响,例如水基液体的严重侵入通常会导致砂拱的破坏,从而引起出砂。油田防砂与防砂预测必须做好防止水侵的工作。
Oilfield sand production will affect the oil recovery and oil recovery rate. Triggering the oilfield sand production for many reasons, such as petrophysical properties, formation pressure, water invasion and gas invasion. In this paper, the author mainly analyzes the impact of water intrusion on sand production in oilfields. Water intrusion has many impacts on sand production in the field. For example, severe intrusion of water-based fluids usually results in the destruction of sand arches, which can lead to sand production. Oilfield sand control and sand control prediction must be done to prevent water invasion.
