1 Overview
At present, China's petrochemical industry in the pumping unit holdings in more than 10 million units, the total installed capacity in the motor 3500MW, annual consumption of more than 10 billion kwh. The efficiency of pumping units is particularly low, with an average efficiency of 25.96% in China and an average of 30.05% in foreign countries . The annual energy saving potential can reach several billion kilowatt-hours. Injection pumps are also important equipment for oilfield production and have great potential for energy conservation. Its normal operation and work efficiency also affect the economic benefits of the entire oil field.
Based on the current status of power generation in oilfield production systems, it is necessary to use energy efficiency monitoring systems for fine management of electricity. Real-time and dynamic energy efficiency management systems will be the basis for implementation of energy conservation, energy conservation evaluation, optimization management and energy auditing by oilfield production enterprises. An Ankerui energy management system used in the reconstruction project of Shengli Oilfield in China, and the implementation of a proven energy analysis management system will provide long-term use of core power data such as electricity quality, energy consumption, and safe operation of oilfield production equipment. Real-time monitoring, dynamic analysis and decision-making, ultimately achieving energy-saving management, and sustainable production
2 Analysis of Energy Consumption of Oilfield Production System
According to statistics, more than 10% of the annual energy consumption of oilfield enterprises is due to the lack of energy monitoring and maintenance plans. Every year, 12% of energy losses result from the lack of energy management and control systems. In addition to computer monitoring and control systems ( DCS , SCADA ), the advanced enterprises in developed countries in Europe and America occupy an important position in online monitoring, analysis, and optimization of energy data. Through modern computer technology, network communication technology and distributed control technology, a complete energy consumption monitoring and management system has been established to realize the informatization, visualization and controllability of the dynamic process of energy consumption, and the structure and process of energy consumption in the production process of enterprises. And factors for management, control, and optimization to improve energy use efficiency.
The main energy consumption of oilfield production units is concentrated in the three energy-consuming systems of machine mining, water injection, and gathering and transportation, including four major types of energy consumption: oil, gas, water, and electricity. The energy consumption analysis and management system mainly focuses on the two parts of electricity metering and key energy consumption equipment (injection pump, oil pump, hot-wash pump, and water pump). Among them, the electricity measurement mainly includes the dynamic monitoring of the data of the main transformer power, water injection, gas injection, machine power, and the measurement equipment power and line electricity of each substation.
3 Application of energy management analysis system in the reconstruction project of Shengli Oilfield
3.1 Project Overview:
 　　 The Shengli Oilfield Geophysical Research Institute's power distribution room was completed and put into operation in 1992. It has been operating safely for 16 years. The distribution system is divided into two parts: high and low pressure. The high voltage part has two 10KV lines in Liaocheng Line A and Zibo Line A, with 6 units. 1250KVA on-load tap-changer. Geophysical Exploration Institute is an important power load user. It mainly includes the second-floor network room processing machine cluster and its supporting electrical equipment; the third floor of the network explains the engine room, LAN server and its supporting electrical equipment, the Bureau Information Center ERP computer room computer and its supporting electrical equipment. The comprehensive building handles and explains the electrical equipment used in the engine room, the refrigeration unit and its supporting electrical equipment, as well as the production and living electricity of the hospital.
The high and low voltage primary equipments were installed fourteen years ago. The original power distribution system used the MS-2801 database definition system. It used many spare parts and had many communication line contacts. It was prone to failure. The operating system was Windows NT 4.0. Application and maintenance It's more complicated. In recent years, with the increase of the power load of the hospital and the expansion of the SP2 fleet, the transformer capacity and the capacity and quantity of the switch of the distribution circuit have been unable to meet the demand of the current power load, and the equipment is severely aged, and the breaker breaking capacity is poor; The power supply company is performing pressure boosting on the oil field, and the original 6KV line has been upgraded to 10KV. The original low voltage bus and transformer outlet switch capacity is insufficient, and the capacitance compensation cabinet has also been aged, and no reactive power compensation is available. In order to ensure the normal operation of scientific research and production in the hospital, we conducted a comprehensive energy management analysis system transformation of the original system .
3.2 Network Structure
This system is mainly composed of three parts: data acquisition layer, data transmission network, and energy efficiency management system software.
1. Data collection layer: Through the intelligent power meter with digital interface installed in the energy consumption monitoring instrument box (cabinet), real-time monitoring of the load power consumption is implemented. Monitoring data includes: electrical parameters such as voltage, current, active power, reactive power, power factor, active and reactive power, harmonics, environment and switch status, and event records. The monitoring objects include: the medium-low voltage feeder circuit on the power demand side, the main energy-consuming electromechanical equipment, and other energy-consuming facilities in the plant (living area). At the same time, it can also use on-site intelligent data collection such as electronic flow meters, electronic heat meters, electronic belt weighers, and ground scales for water consumption, gas consumption, heat, feed quantity, and production volume, according to site conditions and system application requirements. The collected data can also be taken from the user's data interface of other intelligent systems. Â
2. Data transmission network: Data collected from energy metering devices are collected in real-time through energy-conservation smart data gateways installed in the energy consumption monitoring instrument box (cabinet), and transmitted to the energy monitoring center through the TCP/IP network. No need for long-distance wiring, construction is simple and reliable. Ruisense smart data gateway provides a variety of access methods, currently supports RS-485/RS-232 bus, optical fiber, industrial Ethernet, 433M wireless, GSM/GPRS/CDMA network transmission and other methods.
3, electricity and energy efficiency management system software: to complete the data acquisition, calibration, analysis, processing, output, system maintenance, authorization use permission hierarchical control, etc.; and the site can run the important data, alarm information, fault information, etc. Corporate decision makers.
