Abstract: The suitable design of natural gas pipeline network in Liaohe oilfield region was studied. Based on the gas consumption characteristics of each oil production plant in Liaohe Oilfield, the pipeline model was established combining with the actual project. The model was used to simulate the pipeline network layout, and study the parameter changes of flow, temperature and pressure. According to the geographical features, the suitable design of the natural gas pipeline network in this region was identified. The results showed that the self-balancing pressure regulation system could solve the problems caused by unbalancing gas consumption and brought by the oil production plant in Liaohe Oilfield. The small directional drilling crossing mode could be used to solve problems of high ground water, more rivers and ditches. The multiple pipeline back-dragging technology in a same hole was used in Liaohe Oilfield for the first time and got good effect.
