In depth analysis of the energy consumption characteristics of the water blending process and exploration of effective energy-saving optimization technologies are of great significance for improving the sustainability and economic benefits of oilfield development. This article explores the impact of water temperature and water ratio on energy consumption in different water blending processes, in order to improve oilfield development efficiency and reduce operating costs.

摘要

The water blending process is an important means of oilfield transportation, and its energy consumption directly affects the economic and environmental benefits of the oilfield. In depth analysis of the energy consumption characteristics of the water blending process and exploration of effective energy-saving optimization technologies are of great significance for improving the sustainability and economic benefits of oilfield development. This article explores the impact of water temperature and water ratio on energy consumption in different water blending processes, in order to improve oilfield development efficiency and reduce operating costs. The article summarizes the basic knowledge of oilfield development and the basic principles of water flooding, and then analyzes in detail the characteristics of the dual pipe water flooding process and the annular water flooding process (including the first and last annular water flooding processes). Based on the principles of thermodynamics and fluid mechanics, an energy consumption calculation model for the gathering and transportation system was constructed, and a systematic analysis was conducted on temperature drop, pressure drop, and energy consumption quantification methods. Taking the X block in the oilfield as an example, the energy consumption of different water blending processes was simulated using Pipesim software, and sensitivity analysis was conducted on the effects of water blending amount and temperature on energy consumption. Research has shown that by optimizing the water mixing temperature and water mixing ratio, both electricity and gas consumption are reduced, especially when the water mixing ratio is 1:4, the increase in gas consumption is significantly reduced. Compared with the three tube heat tracing process, the end loop water mixing process can achieve a 58.7%–62.4% reduction in operating costs, saving an annual cost of 532,100 yuan per year. The research conclusion provides empirical analysis and theoretical basis for energy consumption optimization of oilfield water blending process, and has important practical application value for promoting oilfield development towards more efficient, economical, and environmentally friendly directions.
