In order to verify the equipment state at each station of the western crude oil pipeline in full load transportation condition, lest its transport capacity and increase the adaptability, conducted is test study on full load transportation capacity of the pipeline. In early test, simulation system is applied to simulate and obtain pump setting schemes at each station of the pipeline in different load transportation capacity steps and determine the control mode and pressure control standard. In test process, gradual increment scheme is adopted in stable conditions of different load transportation capacity steps. Test results show that different oil properties in different batches have large effect on friction along the pipeline and identified are 6 risk points in operation condition of full load transportation capacity. Therefore, more attention shall be paid to changes of oil properties in the western oil pipeline in full load transportation capacity condition so as to avoid operation risks and assure safe and proper operation of the pipeline.
