香豆胶水基压裂液研究与应用

Study and application of Fenugreek gum water base fracturing fluids

介绍了香豆胶化学组成和分子结构、香豆胶稠化剂主要性能、香豆胶压裂液组成和主要特性以及香豆胶压裂液在高温、超深井的现场应用情况.室内研究和现场应用表明,香豆胶性能优异、水不溶物低、增粘能力强、易交联、成本低,形成的水基冻胶粘度高、摩阻低、残渣少,可满足高温、深井油藏和复杂压裂工艺的要求。

The property, chemical composition, and molecule structure of fenugreek gum , the composition, special points of fenugreek gum fracturing fluids are introduced. This system was successfully used in high temperature and super -deep wells in 4 oil fields. It is shown that this system possesses lower friction, good thermal stability, lower solid residue, and good proppant carrying capacity.
