10 years' first drop in water injection in Daqing Oilfield

10 years' first drop in water injection in Daqing Oilfield

Page view

  CNPC news Daqing oilfield vigorously implemented the strategy of reducing cost and increasing efficiency. In 2017, the development system enhanced the water injection and liquid production in both fields by strengthening the comprehensive adjustment of both ends. The annual water injection of 723 million cubic meters, the decline of 1.46%, the first negative growth in the last 10 years, the annual growth rate of 0.68%, the lowest in 10 years.

  The Daqing oilfield, which has been developed for nearly 60 years, has generally entered the period of ultra high water cut, with an average water content of more than 94%, which is figuratively compared to "fishing in water". And the oil and water treatment system has also been occupying the largest proportion of the cost of oil field development, the greater the amount of injection and production, the more comprehensive electrical consumption. In order to cope with low oil prices, the Daqing oil field is constantly improving the quality and efficiency of development and exploring new ways of benefit development.

  The benefits of the development concept, development system set up the cost reduction implementation plan, including three key measures in two are involved in water injection, production control, is a water control, fluid control and control machine wells pump detection rate is two tons of liquid water, control lifting and transportation integrated unit consumption energy consumption. According to the plan, the comprehensive adjustment of the inefficient and ineffective cycle recognition and control is carried out throughout the year. The annual water injection is reduced by 45 million 960 thousand cubic meters, and the annual liquid output is reduced by 17 million 800 thousand tons, so the electricity consumption cost is reduced by 278 million yuan.

  Technological innovation plays a major role in the comprehensive adjustment of the development system. Oil production plant around the "water control and improve the efficiency of the main line, design and optimization of technology innovation project, by means of multi discipline research results, aiming at the spacing block and the high water cut block, take advantage of the corresponding seepage channel identification technology and piezoelectric switch of water plugging technology, identify the inefficient circulation layer, the development trend is steadily for the better. Six production plants improve the inefficient and ineffective cycle automation recognition platform in Lamadian oilfield, for different types of invalid control technology, measures limit, economic benefit evaluation cycle of deepening the study process, the iterative upgrade long plastic tube blocking advanced comprehensive treatment of invalid circulation, 2017 invalid injection of 2 million 460 thousand cubic meters, producing 2 million 106 thousand tons of liquid is invalid.
