通过对 QWEQ型稠油降粘剂的室内评价和现场应用 ,解决了塔河油田超深井因稠油粘度太高而难以采出的问题。以较少的加药量实现了较好的乳化效果 ,实现了井筒降粘以及地面管输变的问题。QWEQ型稠油降粘剂对塔河油田有较好的适应性及较好的降粘作用。本文主要介绍了 QWEQ型稠油降粘剂的降粘性能和应用实例 The indoor evaluation and field application of QWEQ viscous oil viscosity reducer solved the problem that ultra-deep wells in Tahe Oilfield are too difficult to produce due to the viscosity of heavy oil being too high. With less dosing to achieve a better emulsifying effect, to achieve a wellbore viscosity reduction and ground tube transmission problems. QWEQ heavy oil viscosity reducer Tahe oil field has better adaptability and better viscosity reduction. This article describes the QWEQ heavy oil viscosity reducer viscosity reduction properties and application examples
