The invention belongs to the technical field of offshore oil exploitation, and discloses an offshore platform injection-production gradient optimization simulation system. The offshore platform injection-production gradient optimization simulation system comprises a computer control center, a control cabinet and a simulation device operation platform. According to the offshore platform injection-production gradient optimization simulation system, an oil production system is adopted as a main system, that is, the self optimization of the unfixed output value of each oil extraction pump is realized, and a total oil extraction quantity corresponding to a final optimized working point is an oil extraction quantity under the most efficient state; a water injection system is adopted as an auxiliary system, and the total water injection quantity of the water injection system needs to follow the total oil extraction quantity, and relative fixed output value optimization during an oil extraction following process is realized; interference between the two systems in the optimization process needs to be processed accordingly, so that final integrated optimization can be achieved. With the offshore platform injection-production gradient optimization simulation system of the invention adopted, the establishment and calculation of relatively complicated mathematical models are avoided, energy consumption is reduced, and a resource utilization rate is improved. The system can be widely applied to other production processes, and has strong universality.
Description
technical field [0001] The invention belongs to the technical field of offshore oil exploitation, in particular to an injection-production gradient optimization simulation system for an offshore platform. Background technique [0002] At present, the efficiency of the injection-production system of offshore oil platforms has attracted much attention. Improving the efficiency of the injection-production system is conducive to increasing the output of petroleum products, reducing energy consumption, and reducing operating costs. However, due to the dynamic characteristics of reservoir water injection pressure and geological injection volume in the production process It leads to the mismatch between the discharge volume of the water injection pump and the injection volume, and the injection-production system has strong nonlinear and strong coupling characteristics, and the control efficiency is not high. Therefore, how to improve the efficiency of the injection-production system...
