针对气井等时试井一般由多个开关井测压周期组成的特点，将每个测压周期流动压力和恢复压力看成是连续作用过程。根据叠加原理，得到了测压周期的无量纲拟压力表达式，研制了新型综合解释典型曲线，讨论了曲型曲线特征。用实例解释说明了新型曲线曲线拟合法的应用步骤，表明该方法不仅易于解释早期压力资料，而且能消除拟合的不唯一性，可提高解释精度。此研究工作对于低渗致密气藏试井解释具有重要的实际意义。

MATCH WAY OF TYPICAL CURVE FOR DRAWDOWN AND BUILDUP CYCLE OF GAS WELL TESTING

Aiming at the character that gas well isochronal testing consists of many drawdown and build-up cycles, the flowing and build-up pressures are regarded as contunuous action process. According to the superposition principle, the formula of dimensionless pseudopressure is derived,the new comprehensive interpreting typical curve is developed, and its character is discussed. It is illustrated that the new way is easy to explain early stage pressure data,and remove non-unique of matching to improve interpretation accuracy.
