高黏减阻剂的研究与应用进展

Research and application of high-viscosity friction reducer

摘要: 近年来，高黏减阻剂逐渐取代瓜尔胶及其衍生物，成为主流压裂液化学剂，并逐渐成功应用于现场。基于此背景，本文从高黏减阻剂的发展历程、性能评价、增效研究以及现场应用4个方面对其进行了阐述。相对于传统压裂液，低浓度高黏减阻剂具有更加稳定的减阻性能，高浓度高黏减阻剂表现出优异的携砂性能，同时还有较低的储层伤害性，有很大的发展潜力。

Abstract: In recent years, high-viscosity friction reducer (HVFR) has gradually replaced guar gum and its derivatives, becoming mainstream chemicals for fracturing fluid, and has gradually been applied in the field successfully. Based on this background, the development history, performance evaluation, strengthening and field application of HVFR are described in this paper. Compared with traditional fracturing fluids, the low-concentration HVFR has more stable drag-reduction performance, and it exhibits excellent sand-carrying performance, which poses lower damage to reservoirs, showing a great development potential.
