水垢形成是石油工业、封堵设备和储层的主要问题,并导致操作成本增加。聚(乙烯基磺酸盐)(PVS)通常用作防垢剂以防止硫酸钡垢的形成。然而,PVS的有效性受到其在储层中的短寿命的限制。在这篇文章中,PVS已经被捕获在复合纳米颗粒(PECNPs)中,改变了它的电荷,从而提高了在岩石表面的吸附。随着周围盐水的离子强度增加,PVS随后从PECNP中释放,使其可逐渐抑制结垢形成。使用聚(乙烯亚胺)(PEI)和PVS的组合制备带正电荷的PECNP。在纳米粒子优化之后,进行静态吸附测试,这证实了纳米粒子的快速和强吸附。驱替液的离子强度的增加用于分解PECNP结构并将PVS释放到溶液中。© 2018威利期刊股份有限公司J.应用聚合物Sci.2019,136,47225.
Precipitate scale formation is a major issue for the oil industry, plugging equipment, and reservoirs and resulting in increased operational costs. Poly(vinyl sulfonate) (PVS) is often used as a scale inhibitor to prevent the formation of barium sulfate scale. However, PVS effectiveness is limited by its short lifetime in reservoir. In this article, PVS has been entrapped in polyelectrolyte complex nanoparticles (PECNPs), altering its charge and thus enabling improved adsorption on the rock surface. As the ionic strength of the surrounding brine increases, the PVS is then released from the PECNPs, making it available to inhibit scale formation gradually. Positively charged PECNPs were made using a combination of poly(ethyleneimine) (PEI) and PVS. After NPs optimization, static adsorption tests were performed, which confirm the nanoparticles' rapid and strong adsorption. An increase in the ionic strength of the displacing fluid was used to decompose the PECNPs structure and release the PVS into solution. © 2018 Wiley Periodicals, Inc. J. Appl. Polym.
