凝析油-气在存在裂缝的双渗介质中渗流的变产量数学模型及其应用

当凝析气藏压力低于露点压力时,有凝析油析出,致使井底附近阻力变大,影响凝析气的采出量,反凝析现象带来了一些特殊的经济问题.选择合理的开发方式,提高凝析气的采收率,成为了当前工作中迫切需要解决的难题.为了控制合理的井底流压常会引起产量的改变.主要针对凝析气在存在裂缝的双渗气藏中的渗流问题,建立气井变产量生产新模型并进行求解,同时选择相关合理参数绘制了试井理论图版,根据试井理论图版利用试井测试数据进行解释,可以得到相应动态参数为气田开发预案提供相应的理论依据.

Variable Output Mathematical Model and Its Application of Seepage of Condensate Oil-Gas in the Presence of Cracks of the Double Permeability Medium

when the condensate gas reservoir pressure is lower than dew point pressure,condensate exhalation.Near the bottom hole bigger resistance,The influence of condensate gas recovery.The retrograde condensation phenomena are some special economic problem.Choose reasonable development way,Timprove the condensate oil recovery factor,has become the current work is an urgent need to solve the problem.In order to control the reasonable bottom-hole flowing pressure,often causes the change of the production.In this paper,in view of the condensate gas in the presence of cracks in the double permeability reservoir seepage problem,new gas well variable-rate production model is established and the solution is to,While selecting reasonable parameters mapped the well test theory chart,according to well test theory chart use try to interpret the well test data,You can get the corresponding dynamic parameters for gas field development plan to provide the corresponding theoretical basis.
