摘要
对有机钛(B-1)交联的改性魔芋胶(GT9-1)压裂液进行了研究,提出了具有缓交性能、适用于80℃左右井温的加砂压裂液配方,考察了该配方压裂液的性能,讨论了配方组成及高价金属离子对压裂液成胶性能的影响。研究结果表明,用有机钛交联的改性魔芋胶压裂液配方简单,悬砂能力强,视粘度适中,具有抗温、抗剪切等性能,可用于80℃左右井温的大型加砂压裂施工。
The gelling fracturing fluids based on a modified Moyu gum,CT 9-1(developed and manufactured by Sichuan Research Institute of Natural Gas Chemical Technology),and crosslinking with an organic titanate,B-1 (developed by Shanghai Research Institute of Organic Chemistry,Academia Sinica),are investigated.As a result of this work some for- mulations of fracturing fluids with retarded crosslinking (gelation) and suitable for use in sandfrac operations at well temperature about 80℃ are suggested.Typical rheological beha- vior,shear-resistance,filter loss,sand carrying and suspending capacity of the recommended fracturiny fluids are presented in comparision with that of the borax-crosslinking ones,and various influencing factors are discussed,including composition and metallic ions.
