近年来，清洁压裂液在国内油气田的实际应用中取得了较好的结果。本文简述了压裂液的组成，介绍了清洁压裂液的成胶机理，并综述了清洁压裂液对煤炭、页岩的物理化学性质、孔隙度以及吸附解吸的影响。通过分析总结发现清洁压裂液能改变煤炭、页岩的物理化学结构、比表面积以及孔隙度，清洁压裂液中含水量越多越会抑制瓦斯的吸附能力，并且清洁压裂液中的一系列添加剂会促进瓦斯的解吸和运移，有利于煤层气、页岩气的开采。

In recent years, clean fracturing fluid has achieved good results in the practical application of domestic oil and gas fields. This paper briefly describes the composition of fracturing fluid, introduces the gelation mechanism of clean fracturing fluid, and summarizes the effects of clean fracturing fluid on the physical and chemical properties, porosity, adsorption and desorption of coal and shale. Through analysis and summary, it is found that clean fracturing fluid can change the physical and chemical structure, specific surface area and porosity of coal and shale. The more water content in clean fracturing fluid will more easily inhibit the adsorption capacity of gas, and a series of additives in clean fracturing fluid will promote the desorption and migration of gas, which is conducive to the exploitation of coalbed methane and shale gas.
