理解裂缝导流能力损害的原因极其重要，它有利于优化压裂设计，获得最大的经济效益，准确分析油气井生产动态。一般地，压裂液对裂缝导流能力的损害包括压裂液残渣、裂缝中残留压裂液的影响、压裂液敏感性损害等。本文将讨论裂缝中粘滞指进的影响，介绍裂缝中瓜胶压裂液破胶后。残留压裂液对保留渗透率的影响，建立支撑裂缝保留渗透率的预测方法。 It is extremely important to understand the causes of the damage caused by the fracture conductivity. It is helpful to optimize the fracturing design, obtain the maximum economic benefit, and accurately analyze the production dynamics of oil and gas wells. In general, the fracturing fluid damage to the conductivity of fractures, including fracturing fluid residue, fracturing fluid residual fracturing fluid, fracturing fluid sensitivity damage. This article will discuss the impact of sticky fingering in the crack, introducing the guar fracturing fluid in the cracked gel. The effect of residual fracturing fluid on retained permeability and the prediction method of retaining fracture retention permeability are established.
