Feasibility Study Report Of Chen Nan Sewage Station Construction Project

With the development of petroleum and mineral resources in China,most of the oilfields in China have entered into the late stage of high water cut.Therefore,it is necessary to study the distribution of energy consumption,analysis of the causes of low efficiency,high energy consumption,energy saving measures to achieve the purpose of energy saving.In this paper,we study the necessity of the expansion project in the South Station of Sheng Li oilfield.In this paper,the present situation of crude oil treatment system and wastewater treatment system in the south station is analyzed.Because of the serious corrosion of the water transfer pipeline and the limited area of the sewage area,it can not meet the needs of the current operation.The reconstruction scheme of Chen Nan joint station,in the crude oil processing by using the principle of energy balance model in accordance with the established object,design ideas are analyzed respectively in crude oil processing system of furnace and pump group and other major energy consumption.Adding the removal and replacement of high frequency pump coalescence device two big transformation scheme,and makes energy calculation and evaluation calculation,according to the results of a comparison of crude oil processing process,choose the more scientific and reasonable treatment process in crude oil;Chen South sewage station design,firstly analyzes the Chen south station the source of wastewater rejection and indicators,and determine the scale of the design,the gravity sedimentation and pressure oil removal technology two scheme for each scheme are the selection of equipment,pharmaceutical screening,and cost calculation.A low cost and high efficiency wastewater treatment process is optimized.And the field design,pipeline design,investment calculation and benefit analysis are presented.Through the scheme planning of the oil and gas gathering and transportation system reformation project of Chen Nan joint station,this paper gets the following conclusions:Through the analysis of the reform and expansion project,the efficiency of the crude oil treatment system is obviously improved,the pipeline design is more reasonable,and the water quality after treatment has been improved obviously.After the implementation of the project,to meet the next 10 years,the station will be the next stop in the next years,the amount of liquid nitrogen 25659m~3/d,sewage volume of work needs.Three,gravity natural settlement plan gravity settlement time is long,stable operation,the whole process uses glass fiber reinforced plastic material,corrosion resistance,engineering investment slightly low.
