摘　　要：以二元醇、环氧氯化物及氨水为原料,合成出一种有机胺黏土稳定剂Pop-2.利用防膨性、抗温性、抗酸碱性、长效性、与无机盐复配、与压井液配伍性及岩心流动等试验对其综合性能进行了评价.该黏土稳定剂加量1％时,防膨率已达84.09％;在20 ～ 150℃、pH为2～12时,表现出良好的抗温能力和抗酸碱能力;抗洗率在90％以上,具有良好的持久性;与现场压井液具有良好的配伍性;同时,该有机胺压井液体系岩心污染后,渗透率恢复率达98％以上,具有较好的储层保护效果.Abstract： In recent years, organic amine clay stabilizer for well killing fluid has been focused at home and abroad. An organic amine clay stabilizer （Pop-2） is prepared by using dihydric alcohol, epoxy chloropropane and ammonia water as starting materials. The comprehensive performance of Pop-2 is evaluated by antiswelling resistance, temperature resistance, acid and alkali resistance, long term efficiency and the capability with inorganic salts, the killing fluid or core flooding. The resuhs indicate that the anti-swelling can reach 84.09% when the amount of Pop-2 is 1.0% of Pop-2. Pop- 2 also has good temperature, acid and alkali resistance when the temperature and the pH are within 20 - 150~C and 2 - 12 ,respectively. At low concentration of Pop-2, the good long-term stability and anti-swelling resistance can be obtained as well. The rate of resistance to washing is above 90%. The capability of Pop-2 with well killing fluid in construction site is good. Furthermore, after the natural core is polluted by the organic amine well killing fluid, the permeability restoration is above 98% ,indicating excellent reservoir protection effect in core experiments.
