In this paper, a quaternary ammonium salt of chitosan was synthesized and the factors affect on the solubility or degree of substitution of product, such as the concentration of alkali, the time of basification, the content of water in system, the time of dispersing and the method of adding epoxyproryltrimethylammonium chloride, were discussed in detail. The product was characterized by IR, DSC, TG and X-RAY diffraction. The effects of time, humidity and temperature on the gases permeability of the quaternary ammonium salt of chitosan film were researched.

The binomial deliverability equation can only be used to describe the high velocity non-Darcy filtering flow. For low permeability fracturing gas wells, due to low permeable property and high flow conductivity of the formation, the filtering flow laws of the formation are different from those before fracturing, and binomial deliverability equation can not be used for the flow condition of gas wells, therefore, new equation is needed.
二项式产能方程只能描述高速非达西渗流,对于低渗压裂气井,地层的低渗透性和裂缝的高导流能力使得其渗流规律已经和压裂前大不一样,二项式产能方程已无法描述气井的生产状况,必须建立新的方程。
