摘要
环氧树脂和酚醛树脂复配是解决油气田漏失的理想试剂。讨论了该堵漏剂的优点和反应机理,对酒精用量、酚醛树脂和环氧树脂的质量比以及固化剂加量进行了优选,最佳配方为:100 g树脂含60 mL乙醇,m(环氧树脂):m(酚醛树脂)=6:4,六次甲基四胺(HMTA)用量(以树脂总质量计)2.0%。该堵漏剂渗透率低,堵漏率可达97%以上,强度高,抗高温,耐水耐油,耐腐蚀性能强。配方用量要结合油田具体的工艺和地质情况进行调整,该堵漏剂不适用于高温(>85℃)漏失层。
The binary composite system of epoxy resin and phenolic resin is a desirable agent for eliminating oil and gas leakage in oil - gas field. The advantages of this plugging agent and its reaction mechanism are discussed in this paper. The optimum formulation of the plugging agent was identified as follows by optimizing the alcohol usage, the mass ratio of phenolic resin to epoxy resin and the addition of curing agent： 100 g resin containing 60 mL ethanol, m （epoxy resin ） ： m （phenolic resin ） = 6 ： 4, hexamethylenetetramine （HMTA） usage （based on total resin mass） = 2.0%. This plugging agent is of low permeability with the plugging percentage of more than 97%. It is of high strength, and has high temperature resistant, water resistant, oil resistant and corrosion resistant performance. The usage of this plugging agent shah be adjusted according to the specific process adopted and the geological conditions. This plugging agent is not applicable for high temperature （ 〉 85 ℃ ） reservoir.
