天然气井下措施作业效果分析与评价方法初探

Result Analysis and Evaluation Methods on Gas Well Stimulation

本文在分析目前井下作业措施效益评价方法的基础上,指出效益评价中的增产气量应为"计算各气井进行措施作业后在气井经济开采寿命期内的累计产量与假定该井不进行措施作业在相同期间内自然递减的油气产量之差",并提出了井下作业措施的直接经济效益、间接经济效益的概念。

By means of analysis on evaluation of gas well stimulation,in the concept of beneficial evaluation,increasing gas production should refers to'accumulated production in e- conomic exploiting period after taking stimulation minus pro- gressively decreasing production during the same period without stimulation'.Two concepts of direct economic benefits and indirect econonfic benefits in gas well stimulation are presented.
