新型廉价活性剂ZHA的制备及性能评价

PREPARATION AND PROPERTIES EVALUATION OF NEW TYPE OF LOW-COST SURFACTANT ZHA

制备了复合廉价活性剂ZHA。研究表明 :产品界面活性优异 ,能与酸性稠油达到 10 -3 mN/m的超低界面张力 ,耐温耐盐性能良好 ,能耐 12 0℃高温 ,2× 10 -2 mg/L的NaCl和 3 5× 10 -4mg/L的Ca2 + 矿化度。产品成本低廉 ,不到常用活性剂OP - 10和石油磺酸盐的一半 ,是一种具有价格优势和市场竞争力的廉价活性剂。

A compounded low-cost surfactant ZHA is developed and its properties are evaluated in this paper.Through lab.research,the results show that the production's interfacial activity,heat-resistance and salty tolerance are excellent,the IFT between ZHA and acidic heavy oil can reach 10 -3mN/m,its heat-resistance can reach 120°C,sodium ion tolerance can reach 20000ppm and calcium ion tolerance 350ppm.The cost of ZHA is low and its costs are less than half of common-used surfactants OP-10 and petroleum sulfonate.
