在石油、化学和原子能等工业中,都涉及到多相管流的问题。在石油开采中,为了使自喷井油管中的油、气、水混合物流动处于最优的工作状态,以提高油井产量,有必要开展垂直管中油、气、水混合物流动规律的研究。本文探讨了油、气、水混合物垂直管流的压降计算,它涉及到油、气、水混合物的性质和产量、井深、油管尺寸与压强之间的定量关系。
In the petroleum, chemical and atomic energy industries, all involve the problem of multiphase flow. In the process of petroleum exploitation, in order to make the flow of oil, gas and water mixture in the wellbore pipe work in the optimal working condition to improve the oil well production, it is necessary to study the flow rule of the mixture of oil, gas and water in the vertical pipe. In this paper, the calculation of pressure drop in vertical pipe flow of oil, gas and water mixture is discussed. It involves the properties of oil, gas and water mixture and the quantitative relationship between well depth, tubing size and pressure.
