【摘要】：針對目前國內低碳烴無水壓裂液耐溫能力差的問題,用戊烷、磷酸酯膠凝劑LPEA-1和黏度促進劑FS-1配制了耐高溫低碳鏈烴無水壓裂液(戊烷基Frac-H壓裂液),并對其性能進行了初步評價。通過室內試驗研究,確定戊烷基Frac-H壓裂液的基本配方為95.8%戊烷+2.0%LPEA-1+2.2%FS-1,按此配制的壓裂液在180s后黏度達到最大;在溫度為130℃、剪切速率為170s~(-1)條件下連續(xù)剪切120min后的黏度大于50mPa·s;破膠時不需加入破膠劑,且破膠液無殘渣;戊烷基Frac-H壓裂液對頁巖儲層的傷害稍大于致密性儲層,但顯著低于水基壓裂液對頁巖巖心的傷害。研究結果表明,用戊烷、磷酸酯和黏度促進劑配制的戊烷基Frac-H壓裂液,可以滿足非常規(guī)儲層高溫油氣井壓裂施工對壓裂液性能的要求。
[Abstract]:In order to solve the problem of low carbon hydrocarbon water-free fracturing fluid with poor temperature resistance at present in China, pentane is used. Phosphate gelling agent LPEA-1 and viscosity accelerator FS-1 were used to prepare high temperature low carbon chain hydrocarbon free fracturing fluid (pentane based Frac-H fracturing fluid) and its properties were preliminarily evaluated. The basic formula of pentane base Frac-H fracturing fluid was determined to be 95.8% pentane 2.0 LPEA-1 2.2 FS-1. The fracturing fluid prepared according to this formula had the highest viscosity after 180s and the temperature was 130 鈩，
