Abstract

The raw materials base of brown coals for the production of heat-resistant polymer–lignite chemical reagents was selected based on a comparison of the technological parameters of water-based drilling fluids treated with various nanomodified powdered complex polymer–lignite chemicals. On the basis of lignin–alkaline reagents, a highly heat-resistant fluid-loss reducer, a complex low-thixotropic thinning agent, a complex inhibitor of shales, clays, and clay minerals, and a stabilizer of unstable clay and argillite deposits were developed.

生产聚合物-腐殖酸盐钻井液的实验技术

摘要

基于对用各种纳米改性粉末状复杂聚合物-褐煤化学品处理过的水基钻井液的技术参数进行比较，选择了用于生产耐热聚合物-褐煤化学试剂的褐煤原料基础。在木质素-碱性试剂的基础上，开发了一种高耐热性的减水剂，一种复杂的低触变性稀释剂，一种页岩，粘土和粘土矿物的复合抑制剂，以及一种不稳定的粘土和泥锌矿沉积物的稳定剂。 。
