摘　　要：反褶积方法将实测资料通过最优化,对整个生产时间求取等效的定流量压力反应,获取全程的压力响应,不存在叠加处理方法产生的误差,也不存在产量史和压力史不完整所造成的误差,从而获得更多的储层信息,可得到比常规解释更多、更可靠的解释结果。现场实例分析表明,在解释长期变产量(多产量)测试资料中,反褶积技术弥补了常规试井解释技术的不足。Deconvolution method,through optimization to the measured data,calculates the equivalent constant flow pressure reaction at the whole production time to obtain the whole process of pressure response. There is no error caused by the superposition processing method or the incomplete production history and the incomplete pressure history,to obtain more reservoir information,get a more and more reliable explanation results than the regular. The analysis of field examples shows that in the interpretation of long-term variable yield( multi-yield) test data,the deconvolution technique compensates the shortcomings of the conventional well test interpretation technique.
