摘要
新型处理剂ＰＸ—２是以聚丙烯腈为原料，经过高温、高压水解后，在６０～７０℃下加入改性剂并经阳离子化而合成的聚合物。分子量及吸附量的测定表明，ＰＸ—２分子量降低，在安丘土上的吸附量明显提高。钻井液性能的评价表明，ＰＸ—２在降低钻井液粘度与切力的同时还降低失水量。抗温性能、泥页岩回收率优于ＮＨ—４一ＨＰＡＮ。
The new PX-2 thinning and filtrate reducer is a synthetic polymer, which is made from polyacrylonitrile hydrolyzed at high temperature and high pressure, and combined with modified agent at the temperature of 60 ~ 70℃, and then be activated by cation. The determination of molecular weight and adsorption power indicates that PX- 2's molecular weight reduced, but its adsorption power on Anqiu clay increased obviously. The evaluation of drilling fluid property indicates that PX-2 can reduce the viscosity, shear and fluid loss as well. It is much better than NH-4- HPAN both in heat-resistance and shale control.
