油田开采已经进入中后期阶段,注水采油仍然是维持地表压力提高油田采油率的重要方法之一。然而油田回注水二氧化碳高、硫化氢含量高、矿化度高以及温度高等特点,部分油田钙镁离子浓度高,造成注水结垢现象严重,分析油田注水结垢的主要原因,做出相应对策尤为重要,本文从分析结垢原因到相应处理方案,对油田结垢治理做出简要分析概述。
Oilfield mining has entered the middle and late stages. Water injection and oil recovery are still one of the important methods to maintain surface pressure and increase oil recovery. However, because of the high carbon dioxide concentration, high hydrogen sulfide content, high salinity and high temperature of oilfield injection, the concentration of calcium and magnesium ions in some oilfields is high, causing serious waterflooding and scaling. The main reason for oilfield waterflooding is analyzed and the corresponding countermeasures are made Important, this article from the analysis of scaling causes to the corresponding treatment options, make a brief analysis of the fouling of oilfields.
