摘　　要：对于低渗油田，压裂是其投产开发的主要措施，压后形成高导流能力的支撑裂缝是获高产的必要条件。然而大量室内和现场资料表明，诸多因素如支撑剂破裂、压裂液中水不溶物、压裂液残渣、地层粘土的运移、地层流体中垢类等，尤其是压后排液不畅，使地层渗透率受到伤害，裂缝导流能力大大降低。通过大量的研究和实验，应用相关处理液对水力裂缝进行处理，可以较好地解除污染恢复裂缝导流能力，提高压后增油幅度，对于改善压裂效果具有很好的作用。The low permeability Oilfield, the fracturing operation is the development of its major initiatives. After the formation fracturing the support of high-conductivity fracture is a necessary condition for access to high yield. However, a large number of indoor and field data show that many factors, such as proppant break down, fracturing fluid in the water insoluble, fracturing fluid residues, the migration clay strata, formation fluid in the dirt, etc., especially rear fracturing fluid impeded, the formation permeability harm conductivity greatly cracks lower. Through a lot of research and experiments, the relevant application processing on hydraulic fracture treatment, can be used to discharge pollution, restore cracks diversion, and increase oil after fracturing rate increase, effective in improving the fracturing of good play.
