陕北某页岩气田压裂返排液处理后的出水用于回注和配制压裂液。针对该处理系统局部结垢严重的问题，对垢样采用扫描电镜/能谱和化学法进行了微观扫描和组成分析，判定结垢物的主要组成为碳酸钙。探讨了结垢物形成的主要原因，并进行了工艺改进。工艺改进后，水处理系统的出水水质稳定，结垢现象明显减少，系统运行良好。
陝北某頁巖氣田壓裂返排液處理後的齣水用于迴註和配製壓裂液。針對該處理繫統跼部結垢嚴重的問題，對垢樣採用掃描電鏡/能譜和化學法進行瞭微觀掃描和組成分析，判定結垢物的主要組成為碳痠鈣。探討瞭結垢物形成的主要原因，併進行瞭工藝改進。工藝改進後，水處理繫統的齣水水質穩定，結垢現象明顯減少，繫統運行良好。

The effluent from the treated fracturing flowback liquid in northern Shaanxi shale gas reservoir has been reused for water injection and fracturing fluid preparation. Aiming at the serious partial scaling problem in the wastewater treatment system,micro-scanning and components analysis on scaled samples by SEM/EDS and chemical method are implemented,and it is determined that the main component of the scale substances is calcium carbonate. The main causes of scale formation are discussed ,and process improvement has been made. After the process im-provement,the water quality of the effluent from the system keeps stable,and scaling phenomenon gets less obvious-ly. The wastewater treatment system works quite well.
