摘　　要：缝洞型碳酸盐岩凝析气藏的投产单井,常采用非定压、非定产生产模式,且储层非均值性强,流体性质复杂,井筒内多相流动,这些都给油气藏动态分析及动态储量计算带来了一定难度。为此探索了综合运用生产数据分析和试井分析的动态储量计算方法,并分析了影响动态储量计算的主要因素。井底流压折算、投产井生产时间、工作制度和见水情况等对动态储量计算结果的影响较大。在计算油气井的动态储量时,综合运用试井分析与生产数据分析方法,可避免投产井生产模式的影响,计算获得的动态储量值更为可靠。The production mode of non constant pressure and non constant production is usually adopted in the single well of fracture vuggy carbonate condensate gas reservoir.Due to strong heterogeneity,complex fluid property and multiphase flow in the wellbore of reservoir,it is difficult to carry out the dynamic analysis and dynamic reserve calculation of the reservoir.In this paper,the calculation method of dynamic reserves based on production data analysis and well test analysis is explored,and the main factors influencing the calculation of dynamic reserves are analyzed.The calculation results of dynamic reserves are greatly influenced by the conversion of bottom hole flow pressure,production time,working system and water breakthrough.When calculating the dynamic reserves of oil and gas wells,the comprehensive use of well test analysis and production data analysis method can avoid the influence of production mode of production wells,and the calculated dynamic reserves are more reliable.
