Abstract
There are some problems in the thermal system of Huabei Oilfield, such as high energy consumption, high operation cost and poor production safety. With more stringent requirements for energy conservation and emission reduction, it is particularly important to replace fuel oil projects and improve the efficiency of heating system.The utilization of waste heat and waste heat resources in Huabei Oilfield and the application conditions of various heat pump technologies were investigated, according to the characteristics of large amount of sewage and high temperature produced by crude oil dehydration in Huabei Oilfield. Aiming at the characteristics of large amount of sewage and high temperature produced by crude oil dehydration in Huabei Oilfield, Pilot Application of Optimized Extracted Water Source Heat Pump Technology, the research results are applied to the the He Yi Station in the third oil production plant, estimating the scale and benefit of saving, finally, the purpose of reducing cost and increasing efficiency is achieved, and the data basis and technical guidance for energy saving renovation of thermal system in the future are improved.
Highlights
As more oilfields are developed, the energy consumption increases. This is true in heavy oil development areas, where the thermal system accounts for over 70% of the total energy consumption
To reduce the thermal power consumption in crude processing and find alternatives to the traditional oil gathering and transmission technique is of crucial importance to oil development
The water source heat pump (WSHP) is a technique that uses the low-temperature low-level heat generated in the surface water that takes in solar energy and geothermal energy to realize shift from low-level heat to high-level heat with small quantities of high-level heat input based on the heat pump principles
Summary
As more oilfields are developed, the energy consumption increases. This is true in heavy oil development areas, where the thermal system accounts for over 70% of the total energy consumption. The current oil gathering and transmission technique suffers such defects as low efficiency, large energy consumption and heavy pollution, taking up 30% ~ 40% of the total energy consumption. As oilfield development enters the middle or late stage, the water content of the crude increases, the ratio of heavy oil rises, the temperature for crude oil dehydration climbs up, leading to a higher consumption of energy. To reduce the thermal power consumption in crude processing and find alternatives to the traditional oil gathering and transmission technique is of crucial importance to oil development
