摘要

阐述了单相流(层流和紊流)、气、液两相流及油、气、水三相流时水平开水手段压降的几种计算方法。用一个实例计算了水平段单相紊流时的压降,结果可知,在长的水平井中,水平段出现紊流时不能忽略压降。当水平段出现多相流时会有显著压降。

Abstract

This paper introduces some method for calculating pressure drop in the horizontal section of horizontal well, including single wphase flow(laminar and turbulent flow), gas-liquid two phase flow and oil-gas-water three phase flow. An example ls used to demonstrate the calculation of pressure drop in case of the single-phase turbulent flow. The results show that the pressure can not be ignored in turbulent flow. There are larger pressure drop in multiphase flow.
