水平井开采石油遇到的几个流体力学问题

SEVERAL PROBLEMS OF FLUID MECHANICS IN HORIZONTAL WELL PRODUCTION IN PETROLEUM ENGINEERING

  • 摘要: 本文从渗流力学和流体动力学方面讨论了利用水平井技术开采石油时在油藏工程和采油工程中遇到的几个力学问题,如水平井产量的计算、水平井非稳态试井及流场分析、水平井井筒内压力降及其对产量的影响、水平井近井油藏和井筒内流体流动耦合等,并提出水平井开采机理仍存在很多基础理论需要研究和解决.

     

    Abstract: Several fluid mechanics problems involving reservoir engineering and production engineering where horizontal wells are used to produce oil are discussed in the present paper, such as,the calculation of production of a horizontal well, the unsteady well test and flow field analysis ofa horizontal well, the effect of pressure drop along wellbore on production of a horizontal well, andthe fluid flow couple both in wellbore and the reservoir near well, and so on. It is suggested that themechanism of horizontal ...
