摘要
洞穴-裂缝-孔隙型气藏具有既不同于均质地层,也有别于裂缝-孔隙气藏,具有特殊渗流机理。目前对洞穴-裂缝-孔隙型气藏生产过程中气井产量变化特征的研究还不多见。文章建立和求解了洞穴-裂缝-孔隙型气藏气井定井底流压生产数学模型,计算分析了产量随时间变化的特征及其敏感因素,为正确认识裂缝-孔隙型储层气井产量变化规律具有指导意义。
Cave-crack-pore gas reservoir is different from the homogeneous layer,as well as different from the crack-pore gas reservoir,it has special percolation mechanism.At present,the research on characteristics of gas well production change in caves-crack-porous gas reservoir was less.The paper established the mathematical model of the cave-crack-porous gas reservoir bottom hole flowing pressure,and the characteristics of the production varying with time was calculated and analyzed,the sensitivity factors of the reservoir were also discussed.These researches provided a theoretical basis for correct understanding fracture-porosity reservoir.
