摘要: 应用复位势理论和势叠加原理等基本渗流理论,进行了数学推导,得出了压裂后水平井的产能计算新模型.该模型通用性强,不仅考虑了多条裂缝之间的相互干扰,而且还考虑了各条裂缝的长度、缝宽、导流能力、缝间距以及裂缝平面与水平井筒之间的夹角对各条裂缝产量的影响.而以往研究中将裂缝按等缝长、等缝宽、等缝间距和等导流能力来计算压裂井产量,在压裂后水平井产能计算中含有偏差.

Abstract: On the basis of the diffusion equation and Green Function,a new model for productivity test of horizontal well after hydraulic fracturing was derived by the superposition principle of potency.In this model,the influences of geometry,location,azimuth and conductivity of fractures on production rate are considered.In addition,the influential factors and the interference between the multiple fractures are also considered.When the production condition is close to the practical situation,this model can be used to accurately predict the productivity of fractured horizontal well with multiple fractures.In former study,the length,width,distance and conductivity of various fractures were regard as equal,which would result in some deviation.

Key words: horizontal well, hydraulic fracturing, productivity test, calculation model
