—Oil and gas pipeline transmission network simulation is important for the petroleum industry. Existing node method monitors node pressure, simulate pipeline flow rate, and identify different risks. However, it may not be efficient enough to meet the real-time requirement. In this paper, we propose to improve the node method with two techniques. Using the node method, Comparing real data, average deviation, goodness of fit and height of matrix should be raised. First, the least square method is employed to replace the fluid distribution method. Second, matrix decomposition and compression are applied to matrix calculation. Experiments are undertaken on synthesis networks with different sizes. Results show that the new method is at least twice faster than the counterpart.
