【摘要】 通过对亚硝酸钠(NaNO2 )与氯化铵(NH4 Cl)反应的化学动力学的研究,得到其动力学方程,阐述了NaNO2 与NH4 Cl放热反应所产生的“热峰”位置的计算方法,介绍了利用NaNO2 水溶液与NH4Cl 水溶液在井下发生放热反应所产生的热量和氮气来处理井下沉积石蜡的有效方法。更多还原

【Abstract】 The reaction kinetics of sodium nitrite with ammonium chloride is studied and the equation of reaction kinetics is acquired. The method for calculating the position of "heat peak" is expounded, which produced by the reaction of sodium nitrite with ammonium chloride. The effective method is introduced to remove downhole wax precipitation using the heat and nitrogen produced in chemical reaction.更多还原
