曹妃甸油田海水冷却系统优化提升项目顺利完成

Core Viewpoint - The optimization project of the seawater cooling system at the Caofeidian 11-1 oilfield has been successfully completed, expected to reduce seawater pump electricity consumption by approximately 84% and save about 2.54 million kWh annually, contributing to the high-quality development of the Bohai Oilfield [1][2]. Group 1 - The initial design of the seawater cooling system for the Caofeidian 11-1 oilfield included two 350 kW seawater pumps, which provided cooling services for high-power water injection pumps and natural gas compressors, essential for the oilfield's production process [2][3]. - As the daily liquid processing volume of the oilfield increased, the cooling demand for related equipment also grew, prompting the establishment of a specialized task force to optimize the seawater cooling system [3][4]. Group 2 - The task force developed a "two-step" modification plan that combined two initial proposals: one involved redundant modifications to the cooling system, while the other focused on expanding the seawater cooling system with a new high-power seawater pump [4]. - The first step of the plan involved converting the lubrication cooling system of the water injection pump to air cooling, reducing reliance on seawater, while the second step added a cost-effective 55 kW seawater pump to enhance system stability and energy efficiency [4].
