In late November 2013, the well-known PLC national brand manufacturer Nanda Automation Technology Co., Ltd. conducted technical training on pumping unit control unit products (RTU) for technical partners and related staff in Shengli Oilfield. It signifies that the application of NATO's NA series products in related projects of Shengli Oilfield has entered a pilot stage in multiple fields.

In March 2013, Nanda Automation Technology Co., Ltd. stood out from many suppliers with its stable and reliable product quality and flexible customized services. Signed a strategic framework agreement with Shengli Oilfield and became a strategic supplier of automation control products in Shengli Oilfield. After that, Nanda Automation Technology Co., Ltd. signed supply contracts with a number of technical service providers in Shengli Oilfield, and sent key customer technical support teams to support them on the spot. The products have been piloted and applied in a number of key test areas of “Four Modernization” management and construction with “standardized design, modular construction, standardized procurement, and informatization enhancement” content in Shengli Oilfield, demonstrating the technology and service style of a famous PLC national brand .

The key applications of NA series products in Shengli Oilfield include: the application of monitoring system for oilfield water injection station, the application of oilfield heating furnace control system, and the application of high-performance pumping unit control and data acquisition.

The oil field water injection station is to compensate for the decay of formation pressure during the production process of the oil field, and it is necessary to use the water injection process to maintain the formation pressure for the business operation of oil recovery operations. The transfer station, also called oil gathering station, is the main transfer link of the gathering and transportation system. Its task is to receive oil from a single well, a well row or a metering station to process crude oil dehydration, mechanical impurities removal, oil and gas separation and crude oil stabilization.

The NA400 medium-sized PLC is used in batch pilot applications on the monitoring system of an oilfield water injection station in a standard demonstration block of a low-permeability reservoir in Shengli Oilfield. These systems require 24 hours of continuous and reliable operation. Under the circumstances of this new standard and strict requirements, NA400 series PLC has added a lot to the construction of Shengli Oilfield with its high cost performance, complete system functions, open application platform, and strong system compatibility. It has won wide acclaim from customers.

Oil field heating furnace is one of the important equipments in oil field exploration and development. Especially in the development of high water cuts and the development of heavy oil and natural gas in large areas of eastern my country's oil fields, heating furnaces are even more important. With the increase in the exploration and development area of oil and gas fields and the difficulty of development, the number of heating furnaces for oil fields is increasing. The heating furnace control system requires 24 hours of continuous work, and the reliability of the product is very high in the field working environment. NA200PLC has won a lot of praise for its excellent quality. A large-scale pilot application has been achieved on single wells and heating furnaces of transfer stations and metering stations in multiple sub-blocks of a standard demonstration block of a low-permeability reservoir in Shengli Oilfield.

Based on the special needs of high-performance pumping unit control and data collection, Nanda Auto Extension Technology Co., Ltd. developed a special pumping unit control unit product (RTU) based on the PLC architecture. It is responsible for the main functions of data collection, power chart measurement, control and protection of each pumping unit, and is the core unit of the lower-level unit.

The pumping unit control unit product (RTU) developed by Nanda Automation Technology Co., Ltd. for Shengli Oilfield. It has been applied to a low-permeability oil reservoir demonstration area of Shengli Oilfield and a Xinjiang oil production plant affiliated to Shengli Oilfield. Xinjiang Oil Production Plant is located in the south of Karamay City, Xinjiang, and the geographical environment is the harsh onshore environment of typical western high temperature in summer and ultra low temperature in winter. In recent years, the outdoor high temperature has reached 44°C and the low temperature has reached -42°C, and the test of product performance is very severe.

The product will also be used in a batch pilot application in a 232,000-ton offshore oil production demonstration block in Shengli Oilfield. This block is an important new offshore capacity project during the “12th Five-Year Plan” period of Shengli Oilfield, and it is one of the national high-quality engineering oilfield blocks. The environment of this block is a typical high-temperature, high-humidity and high-salt marine environment, and the test of product performance will be extremely severe.

Shengli Oilfield is my country's second largest oil production base. The "four modernizations" management and construction with "standardized design, modular construction, standardized procurement, and informatization improvement" as the content is an important starting point for improving the production management level of Shengli Oilfield. Under this background, the pilot application of Nanda Autotop Technology Co., Ltd. products in the national high-quality engineering oil field block has important demonstration significance for the brand upgrade and market expansion of Nanda Autotop Technology and the promotion of the development of the petroleum industry by industrial control companies.
