Temperature Drop Transportation Scheme Optimization of Oil Gathering and Transportation System in Weixing Oilfield

Abstract:

Wax crystallization characteristics, properties of viscosity-temperature and cold rheological properties of crude oil systems with different water cut are studied to analyze the feasibility and advantages of developing temperature drop gathering and transportation in Weixing Oilfield. On the basis of the characteristics of single pipe loop gathering and transportation technological process, an optimization mathematical model for oil gathering and transporting system operation is established, which objective function is the minimum energy consumption of the system. And to solve the model, the hierarchic optimization strategy is adopted. Optimization results of No.1 department and No.2 department showed that the water blending temperature is reduced more than 8°C and the water blending amount is decreased 20%. According to the optimization scheme, the saving on gas and electricity are 7.12×10⁵m3 and 8.92×10⁵kW•h each year.
