| 摘 要： | 对埋藏浅,油层温度低的油藏进行压裂改造,需解决压裂液低温破胶水化的问题。采用活化剂来提高过硫酸铵(APS),酶,胶囊破胶剂的低温破胶能力。通过对有机硼交联的羟丙基瓜胶(HPG)压裂液低温下破胶后粘度损失率的测定,筛选出用于50℃下的APS/活化剂破胶系统及胶囊破胶剂。结果表明:在APS/活化剂破胶系统的作用下,采用有机硼作交联剂的HPG压裂液在较低温度条件下能彻底破胶水化。

| Abstract: | It is necessary to solve the problem of fracturing fluids being broken in shallow and low temperature reservoirs. Catalysts under low temperature accelerate the breaking capabilities of ammonium persulfate (APS), enzyme and encapsulated breaker. By testing viscosity losses of hydroxyprophyl guar(HPG) crosslinked by borane, some APS/catalysts systems and microencapsulated breaker have been screened at 50℃. Results have been shown that the HPG fracturing fluids can be completely destroyed by APS/catalysts. |
