“…Therefore, the research on automation and intelligence of oil and gas exploitation technology is of great guarantee significance and economic value for national development and industrial progress. The continuous exploitation of oil fields for many years makes the properties of underground crude oil change, such as viscosity increase, exhaustion, and even the oilfield become unrecoverable dead oil due to lack of displacement energy [5][6][7][8][9]. In industry, water injection technology is often used to stabilize the pressure difference between oil zones and improve oil recovery efficiency.…”

As the driving energy to deal with the decrease of interlayer pressure caused by continuous oil production, the layered water injection technology has the characteristics of inhibiting the decrease of oil production and slowing down the increase of oil/gas ratio. In engineering, water injection technology is often used to improve the properties of crude oil, such as excessive viscosity, weak liquidity, and depleted storage, to avoid the formation of dead oil. Injecting appropriate amount of water into different production horizons can effectively maintain the formation water injection pressure, improve the sustainable development speed of the oilfield, ensure the oil production and effectively control the production cost. It is of great value to petroleum engineering and has been widely concerned by the industrial and academic circles at home and abroad. With the continuous development of oilfields over the years, most oilfields have become high-water-cut oilfields. Through the existing layered water injection technology, there are defects such as high labor cost, low operating efficiency, and long commissioning cycle. The ratio of water injection cost to constant increase gradually decreases, and the technical shortcomings become more and more obvious, which is difficult to meet production needs. It is urgent to study and optimize water injection technology scheme to meet oilfield production and technology iteration. In recent years, electronic technology, communication technology, automatic control technology, and other advanced production technology applied to geological exploration, logging technology fields such as engineering, oilfield development is towards integration and intelligent direction, which makes the advanced control and real-time communication intelligent power precision, and the layered water injection technology is possible. This paper summarizes the development history and status quo of oil recovery stratified water injection technology at home and abroad and points out that there are technical bottlenecks and development limitations in the development of water injection technology at present. Focusing on the current hot spots of intelligent oil recovery stratified water injection technology, the advantages and disadvantages of various intelligent water injection technology are compared and analyzed. It provides a certain theoretical reference value for the theoretical research and engineering application of intelligent stratified water injection technology to the equipment design and production of oilfield production and oil recovery technology research institutes and technology and equipment manufacturers.

The world's energy requirement has been dominated by petroleum-based oil for centuries in many application fields, including transportation, household, and electricity. Mineral oil as one of petroleum-based product; an important insulating material in power system has been used more than 150 years. Mineral oil application in power system equipment can be potentially hazardous to the environment especially when there are any incidents during operational time like transformer explosion, which may cause a spill of oil to the soil or water stream. Due to the concerns about the reducing petroleum resources and the environmental issues, the alternative insulating oil with biodegradable characteristics has been attracted lots of attentions for a couple of decades. The purpose of this research work is to investigate the partial discharge characteristics of palm-based oil, namely palm fatty acid ester (PFAE) as biodegradable oil for power transformer oil application. The characteristics then compared to other biodegradable oil, namely soybean-based oil and commercially available mineral oil for further analysis. The effect of electrical stress and ageing time on the oil samples were performed in this work. The results revealed that the partial discharge characteristics of PFAE are similar with commercially mineral oil. Particularly, PD magnitudes of PFAE are slightly lower than those of mineral oil samples during the ageing time. Therefore, PFAE has a good potential to be used as power transformer oil in electrical power system application.Keyword-partial discharge characteristics; alternative insulating oil; biodegradable oil; palm-based oil; mineral oil; power transformer oil.
