【摘要】 随着我国东部油区进一步开发 ,井内出砂、出水问题日益加重。油田地面集输管道中砂、油—水固液两相流动对管道破损起着至关重要的作用。本文通过对固液两相流流型的研究 ,得出了广泛意义上的流型判断计算公式。据此寻找控制流型的最佳参数 ,对实际生产具有一定的指导意义。更多还原

【Abstract】 With further exploration of eastern oil fields in China,the problem that sand and water accompanied with oil become more serious.Sand and oil water solid liqid (SL) two phase flow plays a more important role in surface transport pipeline.In this paper,flow pattern calculation formula are obtained through the study of sand and oil water two phase in the pipe,the optimized parameters controlling the pattern can be found so as to solve problems in productive process.更多还原
