Under the situation of low oil price, the production and management condition of Shengli oil production plant is getting more serious. In order to improve the level of investment decision-making, ensure sustainable and stable development and maximize production efficiency, scientific and reasonable investment decision-making analysis plays an important role in its long-term and efficient development.
The ultimate purpose of this project is to improve investment quality. Based on existing implementation effect statistics of capacity projects, we extract experience and rules, establish evaluation standards of key indicators（output, investment and cost）under different classification conditions, provide data support for rapid and simple feasibility study review, and strengthen risk control in early stage of investment projects, which enables construction unit to standardize feasibility study of investment projects.
At present, the development of Shengli Oilfield is in middle and late stage, and the benefit rate is hard to improve. Two major problems include: first, poor quality of new reserves has caused difficulties in economical and effective production. In recent years, low permeability reserves accounts for 34% and heavy oil accounts for 29% in the newly produced reserves, so new well output has decreased gradually. In addition, the price of crude oil is at a low level in recent years, so it is more difficult to develop reserves in economical and effective way. Second, the million-ton capacity development project of Shengli oilfield is high in investment and difficult in operation. Recently, by means of optimizing production reserves and strengthening investment control, its investment, which is 5.85 billion yuan in 2019, has been controlled effectively, but still not low enough. Therefore, it is necessary to analyze and optimize key nodes of investment decision-making process, adjust investment direction, structure and scale, promote pulling effect of investment, reduce breakeven oil price of branches, realize economic and efficient exploitation of crude oil reserves, and support high-quality development of oil fields.
In accordance with requirements of the 14th five-year plan, this project aims to make overall planning and optimization and improve surface layout and technology on the basis of whole block and entire field. Basing to the ideas of "regional planning, simplified function, optimized process, skid mounted intensification, information improvement, quality benefit, safety and green", we review the whole process and nodes of surface system (water injection, oil production, oil and gas gathering, transmission, water and electricity supply), and conduct a closed-loop analysis from wellhead to combined station, from produced-water treatment station to water injection well .Through optimization and improvement, a new simplified and efficient model of oil field surface system has been built, realizing the strategic development purpose of green, low-carbon and high energy efficiency. The key project of "point, line and area" in typical demonstration area of Shengli Oilfield "(with an investment of nearly 120 million) has been implemented already.

According to adjustment and deployment policy of shale gas field three-dimensional development, the construction mode of "one program, multiple well groups" has been built, which can ensure rapid and accurate selection of technological process, speed up project approval and decision-making process, and realize design standardization. We have proposed the application program of large-scale shale gas field pressurized production for the first time. In accordance with gas field development mode, pressurization opportunity and pipe network conditions, the pressurization mode of gas gathering station was chosen by calculating waste pressure and investment return of gas wells under different pressurization modes. The economic and technical pressurization modes for the whole life cycle of shale gas field have been formed.
Through technical demonstration, the technology of "downhole throttling, series gathering and transportation" is adopted to realize low-cost continuous gas gathering in both winter and summer. The pressurization mode shall be designed according to the pressure decline of gas reservoir, environment condition, surface facility capacity and requirements of natural gas export pressure. Standardized design of well pad, gas gathering station and centralized treatment station. Patented low point condensate drainage device, photovoltaic single well injection device, unpowered alcohol injection device, intelligent simulation switch well and other technologies are adopted to solve the adaptability of ground system.

The power grid dispatching and monitoring system transformation of Shengli Oilfield has three phases. The first phase’s investment is 58.76 million yuan, which has been put into operation in 2013; The investment of phase II project is 243.14 million yuan, which mainly involves the transformation of 94 transformer substations, the construction of 9 centralized control centers and the building of more than 850 kilometers of communication optical cables. The goal is to realize centralized control of substations and improve operation and management level of oilfield power grid through transformation of power dispatching automation system and construction of monitoring automation system on the basis of comprehensive automation of substations. After the project has been put into operation, contradictions such as unbalanced human resource structure, structural shortage of substation operation and maintenance personnel can be resolved. By means of adjusting power grid dispatching management mode and building new centralized control dispatching center, the centralized control of unattended substation can be realized. Total 346 employees can be decreased annually, which will effectively alleviate the impact of aging employees and structural shortage of personnel on the operation of power grid, and guarantee the capacity of oilfield power grid. This project won the second prize of 2016 excellent consulting project of Shandong Province.

The domestic sewage of Beijing Shengli hotel was treated in septic tank without other sewage treatment facilities before. By testing, its COD and ammonia/nitrogen content have exceeded national standard. Therefore, Beijing environmental protection department proposed time-limited rectification notice to Beijing Shengli hotel. The project period covered the 70th anniversary of the founding of PRC, so the management and requirement were particularly strict in Beijing. We organized project group scientifically and carried out design, procurement and construction actively. Taking advantage of EPC management, we completed the project before winter, saving investment for customer.
In 2019, we undertook the environmental detection project during the construction period of crude oil pipeline from Dongjiakou to Dongying by which we won the title of "excellent technical service unit in 2020" of the eastern crude oil storage and transportation Co., Ltd. of the national pipe network group.
Volatile organic compound leakage detection and repair (LDAR) service applies scientific detection methods and information technology to equipment leakage and emission management, which can help petrochemical enterprises to establish a systematic LDAR database management system.

Tank mechanized cleaning refers to tank cleaning process through mechanized equipment such as circulating pumping skid and washing gun. During the process, the no-flow residues and sediments in the target tank would gradually get fluidity from pressurized external media and be sucked out by suction pipe with the liquid media in the tank together. This process needs to be repeated for several times in order to take most of the residues and sediments out of tank.
The system includes both traditional energy and new energy. With different levels of energy-saving indicators as guidance, closed-loop management of energy as the method, and in consideration of the actual needs of energy consumption management of energy users, we establishes an energy management and control information system that can connect all management levels vertically and cooperate with parallel units horizontally, so as to realize dynamic monitoring of energy consumption and accurate control of energy efficiency indicators, providing long-term energy-saving guarantee for energy consuming enterprises.
