[Abstract]:Hydraulic calculation and analysis of oil field water injection pipe network is of great significance to network reconstruction, expansion, check pipe network node pressure value, pipe flow distribution, pipe friction coefficient, energy consumption analysis, to ensure the normal operation of the pipe network system. According to the characteristics of ring branch water injection pipe network in a certain oil production plant, the hydraulic calculation model of ring branch pipe network is established by using the principle of node method, and the improved boundary condition treatment method is put forward. The model has strong adaptability and can satisfy the annular shape. Under different boundary conditions, the demand for hydraulic calculation of branched and annular branch pipe networks is fast. According to this model, the hydraulic simulation software is compiled and applied to the water injection pipe network of a certain oil production plant. Compared with the actual data, the average error of pressure calculation is 2.98 and the average error of flow calculation of water injection station is 3.32. The calculation results show that the model can meet the engineering needs.
