摘要:
动能压降会影响水平气井的产能,传统的水平气井产能公式不考虑动能压降。为了得到水平气井井筒的压降方程,把水平气井水平段看作水平管路,利用气相管流基本方程,得到不同流入剖面条件下井筒中的压力梯度,经过积分得到水平气井跟部和趾部之间的压降方程,进而得到井筒中的流动阻力。根据Joshi公式得到水平气井在水平面和垂直平面上的渗流阻力,再结合井筒中的流动阻力,利用等值渗流阻力法便可得到水平气井的产能公式,再结合Dikken方法最后优选出水平段的长度。
Abstract:
The level of horizontal gas well productivity is affected by wellbore pressure drop.But the conventional productivity formula of horizontal gas well does not consider the wellbore pressure drop.In order to obtain the wellbore pressure drop equation,the horizontal section of the gas well was considered as horizontal pipeline,and assuming that a uniform formation fluid flows into the wellbore,the pipeline friction losses between any two sections were obtained by Bernoulli equation.And then the wellbore pressure gradient and the friction loss between the heel and the toe of horizontal wells were got under laminar or turbulent conditions.According to the formula of Joshi,the frictions on the horizontal and vertical planes were calculated.Combined with wellbore friction,a productivity formula of horizontal gas well under laminar and turbulent flow conditions was established by the equivalent flow resistance method.Finally,the length of the horizontal section was optimized combined with Dikken method.
