摘要

在已有研究的基础上，主要针对硫酸钡锶垢在化学防垢剂优选及评价、结垢监测技术、提升化学挤注工艺和水力压裂阶段固体防垢技术等4方面开展了研究与试验，有效提高防垢效率和防垢工艺有效期，控制成本。对于国内海上油田、低渗透油田不同开发阶段的结垢防治有一定的借鉴意义。

Abstract

Based on the existing research and in the light of barium strontium sulfate scales,the research and experiments are carried out in four aspects such as the screening and evaluation of chemical anti-scaling agents,scale inspection technology,scale-inhibitor-squeeze treatments and solid scale inhibitor application in hydraulic fracturing stage.These measurements can enhance the anti-scaling efficiency,prolong the valid period of anti-scaling process and control the comprehensive production cost.These researches have certain references to the scale control in the different stages of China's offshore and low-permeability oilfields.
