Abstract: In this paper,varying rat a production are studied using tlae concept of instantaneous ponit soiuce solutions.When the flow rates vary linearly with tune or were approximated by a cotmbina,tian of linear sections,this paper gives simple analytical formulas for pressure buildup test,ie;Eqs.(8)(10)(14)(15)(16) and Fig.3.In these Eqs.,Q_odenotes the initial flow rates;Q_s denotes the flow rate at shutin times;p the original reservcair pressure;and t_s the shut-in time.

摘要： 本文由瞬时点源解的概念出发,研究了变产量情形的压力变化.对于产量随时间近似按线性变化,或者分段按线性变化的情形,给出了压力恢复分析的简单解析表达式.
