以有机硅、松香树脂、石英粉和陶粒等为原料,研制出一种新型双组分井下固化下沉式缝高控制剂。其中A组分为固体颗粒,B组分为液态固化剂;施工时将双组分混合均匀后,随携砂液注入井中,然后在井温条件下沉降固化。重点讨论了体系的初凝时间与温度的关系,以及B组分含量、井温和反应时间等因素对最终隔层强度的影响;利用显微镜技术观察了体系固化前后的微观结构变化,采用热重分析(TGA)法计算了液态B组分固化剂的利用率。结果表明:该缝高控制体系适用于井温为50～70℃的油井,得到的隔层可增加地层应力5～7 MPa,B组分的利用率为71.78%;该产品控缝效果良好,是一种应用前景较好的石油开采用缝高控制剂。
With silicone, rosin resin, quartz powder and ceramsite as raw materials, developed a new type of two-component underground sinking seam height control agent. The A component is a solid particle and the B component is a liquid curing agent. During the construction, the two components are uniformly mixed and then injected into the well along with the sand-carrying liquid and then settled and solidified under the well temperature. The relationship between the initial setting time and the temperature and the influence of the content of B component, well temperature and reaction time on the strength of the final separator were discussed. The microstructure changes of the system before and after curing were observed by using the microscope. The thermal gravimetric analysis (TGA) method to calculate the liquid B component curing agent utilization. The results show that the seam height control system is suitable for well with well temperature of 50 ~ 70 ℃. The obtained interlayer can increase the formation stress of 5 ~ 7 MPa and the utilization rate of B component is 71.78%. The control effect of the product is good, It is a kind of seam height control agent for petroleum exploitation with good application prospect.
