缓胶压裂液技术在川西沙溪庙低渗气藏的应用

THE APPLICATION OF THE DELAYED CROSS-LINKING FRACTURING FLUID TECHNOLOGY IN LOW PERMEABILITY GAS RESERVOIR OF SHAXI-MIAO IN WEST SICHUAN

文中介绍了一种缓胶压裂液技术。该技术配制的压裂液具有良好的延迟交联性能和延迟破胶性能 ,适合于大规模、大排量加砂压裂 ,且破胶彻底 ,返排迅速。现场应用表明 ,该压裂液技术对低渗油气藏的增产效果十分明显。

This paper describes a new technology of delayed cross-linking fracturing fluid.The fracturing fluid has a good property of delayed cross-linking and delayed gel-breaking.It is suitable for large-scale and high pumping sand fracturing and gelbreaking is thorough and flowback is quick .Field applications indicate that this fracturing fluid technology has obvious stimulation results in low permeability gas reservoir.
