【摘要】：為降低本溪組壓裂液對地層的傷害,研究開發(fā)了適合延安氣田本溪組儲層的低濃度胍膠壓裂液體系。實驗結(jié)果表明:低濃度胍膠壓裂液當胍膠質(zhì)量分數(shù)為0.3%時,在100℃,170s的剪切速率下經(jīng)過120min耐溫剪切,粘度保持在200m Pa·s~(-1);殘渣含量和巖心傷害率明顯低于常規(guī)胍膠壓裂液體系。該體系在延安氣田本溪組試驗2井次,表現(xiàn)出攜砂能力強、低摩阻、返排效果好等優(yōu)點。
[Abstract]:In order to reduce the formation damage caused by the fracturing fluid in Benxi formation, a low concentration guanidine gel fracturing fluid system suitable for Benxi formation reservoir in Yan'an gas field was developed. The experimental results show that when the mass fraction of guanidine gel is 0.3, the low concentration guanidine gel fracturing fluid is shearing under the shear rate of 100 鈩，
