针对传统防漏剂的局限性，研制了一种新型自结合防漏剂。自粘失循环剂为固体状，形状不规则，可与水发生反应。反应产物填充在颗粒之间并将颗粒粘合在一起。自粘失循环剂的固井速率和固井体的抗压强度受温度、粒径和添加的助剂的影响，可通过改变粒径和添加的助剂进行调节。固井体具有一定的渗透率，且渗透率可调，可用于控制储层漏失。
In view of the limitations of traditional lost circulation agents,a novel self-bonding lost circulation agent was prepared.The self-bonding lost circulation agent is solid and irregular in shape,and can react with water.The reaction products fill between particles and cement the particles together.The cementing rate of the self-bonding lost circulation agent and compressive strength of cementing body is affected by temperature,particle size and added additives,which can be adjusted by changing particle size and added additives.The cementing body has certain permeability and the permeability can be adjusted,so it can be used to control lost circulation in reservoir.
