The Gas And Non-Newtonian Fluid Multiphase Mixed Flow Laws, Hydraulic Calculation Methods And Write Software

In the process of oil and gas field production, it is necessary to gather and transmit crude oil, water and entrained gas rationally. The multiphase mixed flow pipelines have great proportion of the surface technological pipe networks in the oil-gas field. It is also a most complex pipeline flow form. With the oil field's development in the seas, deserts and shallow seas, the requirement for multiphase pipeline flow technology is becoming more and more urgent. The oil gas water multiphase mixed is a technology of study and development in the oil field's development domain, but the study for the oil gas water multiphase flow laws is an important content of the oil and gas mixed flow. The water-bearing oil's rheological property exhibits the non-Newtonian fluid's property in the certain situation. Frequently, the gas and non-Newtonian fluids, the two phases flow is the main form in the surface multiphase mixed flow pipelines.In this paper, It is reviewed that the development history of the gas and two-phase flow study, part and to the point introduce calculation method in the pressure drop of the liquid as Newton or non-newton in the multiphase mixed flow pipelines. The formula for the multiphase flow's press-drop loss at different regimes can be obtained on the basis of much theoretical, experimental study and the flow mechanism. By write the program, and daqing oil field true measure dates in reality produce, The feasibility of the calculation method is tested of suity this area. The related method is recommended by analyzing, assessing and proving in the calculation results.
