Abstract: China is a big oil and gas consumer with Russia as one of its major importers. There are abundant oil and gas resources in Russia's Sakhalin offshore. In recent years, large-scale development has been carried out through joint ventures and cooperation. From the perspective of reference, the oilfield distribution and development process of Sakhalin-1 project were traced. The land drilling rig, offshore drilling platform, land combined station, oil and gas transmission pipeline, land oil and gas terminal and other equipment and facilities of Sakhalin-1 project were investigated. The achievements of Sakhalin-1 project in oil and gas output, technological progress and social benefits are summarized. The future development of sakhalin-1 project is prospected. The analysis shows that the cooperative development of Sakhalin-1 project in Russia has achieved great success, which plays a reference role for the cooperative development and technology introduction of China's oilfield. Sakhalin is close to the northeast of China, and the oil and gas of Sakhalin-1 project is expected to enter the northeast of China and relieve the oil and gas tension in China.
