摘要
本文概括介绍了原油降凝降粘剂ＨＣ的基本组成、作用原理和性能指标，详细介绍了在中原油田采油三厂各类稠油生产井中投加ＨＣ的降凝降粘开采工艺，简要说明了现场应用结果。
low improver HC for viscous crude oils is a downholeused chemical agent composed of a polymer of long chain acrylates as pour point depressor, a polymer waxing inhibitor, surfactants, benzol blends, light distillation fractions, etc. In this paper the composition, functions and properties of HC are introduced in general and the field uses of HC in 38 production wells of high pour point and high viscosity crude oils are described in detail for the aimed well selection, the ways of chemical injection, the timeperiod between two injections, and the amount of chemical injected into one well.
