However, the facilities can not meet the development need due to high operation cost. Upgrade is greatly needed to to ensure processing operation and to save the operating costs. Considering the current problems of the existing facilities after comprehensive analysis, feasibility on upgrading the old zone of HongGang oil field was developed. Feasibility is performed through analysing the factors such as natural condition, social enviroment, current condition and development plan. The feasibility includes oil storage and transportation, produced water treatment and fire fighting system, electricity system, plot plan, architecture and structure, energy and environmental protection and HSE. Financial assessment methods were done in order to get the best economical efficiency. Based on the adequate theory and practice, this article makes objective analysis and explanations to the refurbishment background, technical conditions, construction, investment estimate, economic benefits of the old area of Hong Gang by applying the quantitative and qualitative, static and dynamic methods, technical economics, theory and application of project management, project finance, human resources management etc., , thus arrives at the conclusion of the feasibility of the project. Technological and economic assessment methods are mainly used for the feasibility evaluation of the project, including the net present value and Internal Rate of Return, Payback Period method. The innovation in this article lies in the combination of theory with practice, surveys and theoretical study, qualitative and quantitative analysis methods. The project evaluation theory, practice and production practice technology is applied for the feasibility evaluation of comprehensive refurbishment in the old area of Hong Gang in order to make the project's decision-making more scientific, objective, rational, and in line with the investment principles of economic efficiency. The project design introduces a lot of new technologies and new products of oilfield surface engineering .It not only can be taken as an guidance for the similar projects in this industry, but also for technical and economic evaluation of the old oilfield readjustment and reconstruction. During the project feasibility study, firstly the extant problems of the old areas of Hong Gang Oilfield Surface Engineering is analysesd, including inadaptation to the development needs, unreasonable layout , backward technology, aging facilities, high production costs. To solve these problems, the design of each system and optimization is conducted based on economic efficiency. And the layout is optimized to solve the extant problems. TheIV utilization of the exsisting facilities and equipments is also considered to avoid redundant construction. Firstly, long-term reconstructed oil field production scale is confirmed. The overall layout is re-established: utilizing the single well and trunk/flow line delivery process, optimizing the pipeline transportation at normal temperature, vacuating the original metering plant, using automatic route measurement and software metering, vacuating and sealing the transfer stations, adopting Two-stage distribution for CPF, adding the separation system and sealing dehydration system and applicable reconstruction of the relevant facilities in CPF . Second, the program works to determine the quantity and investment estimate. The estimated investment is 174,627,100 Yuan, and according to the project economic evaluation, financial evaluation, the pre-tax internal rate of return is 27.51% , after-tax internal rate of return is 20.24%, both of them are higher than the industry benchmark rate of return. The payback period 4.32years, 110.56 million Yuan of pre-tax net present value and 56.52 million Yuan of after-tax net present value are above zero. The above key financial indicators indicate good financial evaluations benefits. After project refurbishment , the achievement of oil and gas gathering and transportation system: Gas Gathering closed: 100%; gas utilization: 100%; furnace average thermal efficiency :> 85%; pump efficiency: 75%. Oil and gas gathering system energy consumption after refurbishment: power: 806x10 4 kW.h / a; gas consumption: 65x10 4 m3 / a; total energy consumption: 4793x10 4 MJ / a. Making the Comparison before and after reconstruction, 28.56 million Yuan cost is saved in operating. The closed system and reduced oil consumption is achieved after refurbishment. The domestic advanced level of 1.20%, while the Hong Gang oilfields is up to 0.5%; Secondly, the energy consumption is reduced by transportation at normal temperature, about 601.5MJ / t, which is lower than the energy consumption level of domestic oil gathering and transportation at normal temperature (945MJ / t). In conclusion, this project has good economic and social benefits, and it is conducive to the sustainable development of Hong Gang oilfields. The refurbishment of the surface facilities simplified the process, and reached the achievement of the low energy consumption, high efficiency, safe and environmental production, and better adaptability. This may have some valuable reference for the similar projects of other oilfields.
