| Abstract: |
| Using the nodal matrix method, a mathematical model was set up according to the quality and energy balance equation for hydraulic calculation of branch form pipe networks for oilfield above ground water injection system. The mathematical model was solved using function of many variables Taylor expansion formula. The illustration was given.The results show that the method has the advantages of high in computing precision, quick in speed and simple in programming. The method is a reliable way for solving hydraulic calculation of bulk branch form pipe networks. The average deviations of calculation value and real value for flow rate and pressure are 4.1%,2.4% respectively.The result is satisfied with engineering requirement. |
