Abstract: China is rich in oil and gas resources in beach and shallow sea areas. Acceleration of efficient development of oil and gas resources in beach and shallow sea areas can help China raise its ability for independent oil and gas supply. It is an important integral part of the nation’s energy security strategy. Dagang Oilfield focused on the bottlenecks in efficient development of oil and gas resources in beach and shallow sea areas, such as the complicated environment and the demand for multilateral involvement and cooperation. In the action principle of “safety, greenness, independence and performance”, the oilfield formulated a “two-step” development strategy, namely beach put first and followed by shallow sea, and gradually accelerated integration of geological-offshore engineering evaluation and productivity construction, integration of offshore and onshore oil and gas gathering and transferring operation and integration of infrastructure construction and operational management. Dagang Oilfield also enhanced independent innovation of technology and process, made breakthroughs in building technology for artificial islands and offshore platforms, and achieved 21 items of technological innovation results of which 12 items were created as the technological results for the first time in China, thus forming a technological family of beach and shallow sea oil and gas development with the Chinese characteristics. Borrowing the advanced experience in modern project management and pursuing the general objective of keeping project progress, quality, safety and investment control in harmony, the oilfield established the characteristic project management system for development of beach and shallow sea oil and gas resources and brought about development of resources in harmony with environmental protection.
