Horizontal Wellbore Pressure and Effect on Horizontal Well Productivity

ZHOU Sheng-tian,QU Hong-yan(College of Mathematics and Computational Science,China University of Petroleum,Dongying 257061,P.R.China)  
Pressure gradient model is established based on variable mass flow in horizontal wellbore.Some calculation methods for wellbore pressure drop are discussed.Because Pressure change along horizontal wellbore affect inflow along wellbore from reservoir,estimated model for horizontal well production considering wellbore pressure drop is introduced and compared with productivity for infinite conductivity.Effect of wellbore pressure on horizontal well performance is considered.It can provide some theory guiding for precise computed horizontal well production and rational predicted horizontal well performance.
