摘要
清洁压裂液作为一种新型压裂液体系,具有清洁、低污染、破胶彻底、残渣少、压后返排率高等特点,在特低渗储层具有良好的应用前景。通过对比常规瓜胶压裂液、低伤害压裂液和清洁压裂液的压裂充填裂缝导流能力伤害实验,定量分析不同压裂液体系对压裂裂缝导流能力的伤害率,从而可以直观评价清洁压裂液对储层的伤害特点,为清洁压裂液的推广应用提供重要依据。
As a new type of fracturing fluid,clean fracturing fluid have the characteristics of cleaning,low damage,thoroughly gel breaking,little residues and high flowback rate.So it will have good application prospect in low permeability reservoirs.About flow conductivity damage experiment of the fracture filling cracks of the conventional guar gum fracturing fluid,low damage fracturing fluid and clean fracturing fluid,and with the experimental results comparison,the fracture conductivity damage rate of different fracturing fluid system is quantitatively analyzd.So clean fracturing fluid damage characteristics for reservoirs can be visually evaluated.This can provide important basis for popularization and application of clean fracturing fluid.
