A MODEL TO CALCULATE PRESSURE DROPS OF HORIZONTAL WELLBORE VARIABLE MASS FLOW COUPLED WITH FLOW IN A RESERVOIR

LIU Xiangping (Tsinghua University, Beijing),ZHANG Zhaoshun, LIU Xiange, et al JOURNAL OF SOUTHWEST PETROLEUM INSTITUTE, VOL. 22, NO. 2 , 36-39, 2000 (ISSN1000-2634, IN CHINESE)  
Pressure drops in horizontal wellbore influence production performance greatly. This paper analysis the property of horizontal wellbore single-phase variable mass flow coupled with flow in reservoir when a horizontal well is producing. The basic equation are derived to calculate the pressure drops of the flow within an open-hole and a perforated completion horizontals well bore based on the principle of conservation of mass and momentum. And the equation of flow in the reservoir is also derived using potential superposition principles. Based on this, a new model to calculate pressure drops in horizontal wellbore is developed. The results of the practical calculations are shown.
