碱性硅酸凝胶固砂剂的初步研究

STUDY ON ALKALINE SILICIC ACID GEL USED FOR SAND CONTROL

碱性硅酸凝胶多用于油井堵水或水井调剂。文中对碱性硅酸凝胶作为固砂剂进行了研究，探讨了碱性硅酸凝胶作固砂剂的机理，并与酸性硅酸凝胶固砂剂对比。结果表明：碱性硅酸凝胶固砂剂具有成本低、无腐蚀、固结强度大等优点，可在油田固砂中推广应用。

Alkaline silicic acid gel is used for water control in producing wells and profile control in water injection wells. The paper studies sand consolidation act of alkaline silicic acid gel and discusses the mechanism of alkaline silicic acid gel used for sand control and contrasts with acidity silicic acid gel. The experimental results indicate that the advantages such as non-corrosive, low cost and high solidifying strength, etc. It's worth popularizing and applying.
