The PAM market for oil production has broad prospects

As a non-renewable energy source, oil has a very limited underground reserves. Under current water flooding conditions, oil recovery is only 35% to 45%, which means that most of the crude oil remains in the ground after the end of water flooding. How to maximize the remaining crude oil in the underground has become an important task for the oil industry. "Developing the west and stabilizing the east" is the development strategy of China's petroleum industry. Improving the underground oil recovery in the late stage of high water cut in the eastern oilfield is an important part of the stable eastern development of China's petroleum industry. Therefore, the development and application of enhanced oil recovery technology is of great practical significance for the implementation of China's petroleum industry strategy.

In the process of oil exploitation, by injecting a PAM aqueous solution, the oil-water flow rate ratio is improved, and the crude oil content in the produced product is increased. At present, there are not many applications of foreign PAM in oil fields. Due to special geological conditions, polymer flooding technology has been widely used in Daqing Oilfield and Shengli Oilfield.

At present, most of China's oil fields have entered the late stage of secondary oil recovery, and the comprehensive oil recovery rate is only 30%. Therefore, the tertiary oil recovery by oilfields has become one of the main measures for stable oil production. The tertiary oil production and oil production in Daqing Oilfield and Shengli Oilfield, which are the mainstays of China's tertiary oil recovery, have increased year by year. In 2009, they accounted for 25% and 12.4% of their crude oil production in 2009.

In oil exploitation, PAM is mainly used in drilling mud materials and improving oil recovery rate. It is widely used in oilfield mining operations such as drilling, completion, cementing, fracturing and enhanced oil recovery. It has viscosity increasing, fluid loss and flow. Variable adjustment, gelation, splitting, profile adjustment and other functions.

PAM flooding is currently the main technical means of tertiary oil recovery, and will continue to be the main method to improve oil recovery in the future. With the increase in tertiary oil recovery demand, the PAM market demand will be very strong, and the PAM market for oil production has broad prospects.
