【摘要】：为降低本溪组压裂液对地层的伤害,研究开发了适合延安气田本溪组储层的低浓度胍胶压裂液体系。实验结果表明:低浓度胍胶压裂液当胍胶质量分数为0.3%时,在100℃,170s的剪切速率下经过120min耐温剪切,粘度保持在200m Pa·s~(-1);残渣含量和岩心伤害率明显低于常规胍胶压裂液体系。该体系在延安气田本溪组试验2井次,表现出携砂能力强、低摩阻、返排效果好等优点。
[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，
