报道了一种聚合物增稠剂zcy-01和交联剂JL-01为基础配制的压裂液。增稠剂zcy-01是一种低分子量聚合物,溶解速度快,在水中完全时间小于20 min;增粘效果好,0.5%浓度的聚合物基液粘度可达63 MPa·s。在酸性条件(pH=5~6)下与酸性交联剂以100∶0.5比例混合形成可挑挂冻胶,该冻胶呈透明状,携砂稳定。该压裂液耐温性好,破胶效果好,残渣含量小于100 mg/L,防膨率达到80.36%,适合于压裂施工。在强1块两口井的压裂施工中,增产效果明显。
A fracturing fluid based on the polymeric thickener zcy-01 and the crosslinker JL-01 was reported. The thickener zcy-01 is a kind of low molecular weight polymer with high dissolution rate and less than 20 min in water. The thickening effect is good. The viscosity of 0.5% polymer base liquid can reach 63 MPa · s. Under acidic conditions (pH = 5-6), the acidic cross-linking agent is mixed with the acidic cross-linking agent in the ratio of 100: 0.5 to form a swabbing gel. The swollen gel is transparent and carries sand steadily. The fracturing fluid has good temperature resistance, good gel breaking effect, residue content of less than 100 mg / L and anti-swelling rate of 80.36%, which is suitable for fracturing construction. Strong one in two wells fracturing construction, the yield increase effect is obvious.
